The result is a transmission purpose-built for Chevelles, GTOs, Cutlasses, Novas, Camaros, and other GM A-bodies with a compact, end-loaded case design that clears most factory transmission tunnels without modifications.

The TCET17805 gear set pairs a 2.87 first gear for strong, manageable launches with a deep 0.68 overdrive that significantly reduces highway RPM for improved fuel economy and reduced engine wear. All gears and shafts are manufactured from ASTM 4615 special grade steel, while the robust internal three-rail shift system with steel shift forks ensures precise engagement through all five gears. Superior shift-ability comes from multi-cone synchronizers and hybrid synchronizer rings made of sintered bronze and carbon, allowing confident shifts at engine speeds up to 7,500 RPM.

TREMEC engineers optimized the TKX's three-piece ribbed aluminum housing for structural stiffness while minimizing noise, vibration, and harshness. Tapered roller bearings on the input, output, and counter shafts reduce noise and improve durability, while caged needle bearings support all gear positions to reduce end play. Oversized gear widths increase gear life and torque capacity, and gaskets at all flanges eliminate fluid leaks and simplify installation.

The TKX bolts directly to standard GM Muncie bellhousings, making it a direct replacement for 3-speed and 4-speed Muncie transmissions. The 26-spline input shaft requires a matching clutch disc, while the 31-spline output shaft provides increased strength for high-torque applications.

Description

When your classic GM muscle car is making north of 400 horsepower and that antiquated 4-speed is holding you back, the TREMEC TKX delivers the overdrive upgrade you need. Unlike transmissions repurposed from OEM applications, the TKX was designed, tested, and built from the ground up specifically for the aftermarket. The result is a purpose-built 5-speed that combines universal packaging with the durability and shift quality that high-horsepower restomods demand.

The engineering focus shows in every component. All gears and shafts are machined from special-grade ASTM 4615 steel for increased torque-carrying capacity. Sintered carbon/bronze hybrid triple-cone synchronizers deliver smooth, precise shifts even at 7,500 RPM. The gear layout is optimized to minimize noise, vibration, and harshness while oversized gear widths and caged needle bearings in all gear positions maximize durability. A ribbed three-piece aluminum housing provides outstanding structural stiffness while keeping weight down to just 99 lbs dry.

The compact end-loaded case design clears most GM A-body transmission tunnels without cutting - Chevelle, GTO, Cutlass, Nova, and Camaro applications typically bolt right in. Three shifter positions offer flexibility for factory console alignment, and the low-profile shifter plate keeps everything tight. This close-ratio 2.87:1 first gear with 0.81:1 overdrive fifth provides strong acceleration while dropping highway RPM for comfortable cruising and improved fuel efficiency.

Description

Swapping a modern 5-speed into your Buick, Olds, or Pontiac muscle car means finding a bellhousing that bridges classic BOP engine patterns with contemporary transmission bolt patterns. This aluminum bellhousing solves that problem with a dual-pattern design that accepts both vintage Muncie/T10 4-speeds and modern TREMEC TKO/TKX 5-speeds, giving you flexibility now and an easy upgrade path later.

The casting is A356 aluminum alloy with deliberately over-thick wall construction throughout. A356 is a premium casting alloy favored for its excellent strength-to-weight ratio and superior castability, making it ideal for drivetrain components that need to handle repeated torque cycling without cracking or distorting. The thicker-than-standard walls add insurance against the stress concentrations that destroy thinner bellhousings over time.

What makes this bellhousing particularly useful for BOP applications is the dual starter pocket design. Buick and Oldsmobile engines use different starter mounting locations, and this casting accommodates both configurations without adapter plates or creative bracket fabrication. The bellhousing works with either mechanical linkage (Z-bar) or hydraulic clutch release systems, so you can retain your factory setup or upgrade to hydraulics without sourcing a different bell.

For street cruising applications under 500 horsepower, this aluminum bellhousing delivers excellent value. If you are building a race car or running over 500hp, step up to a steel bellhousing for maximum safety. Flywheel cover plate (MD-401-1117) and pivot stud (MD-401-6026) available separately. Made in the USA.

• Designed for TREMEC TKX 5-speed transmission installations
• Proper thread engagement depth for aluminum threads -- prevents bottoming out or insufficient engagement

Description

Bolting an aluminum bellhousing to your BOP V8 requires fasteners with the correct length for the casting thickness -- use steel bellhousing bolts and you risk either bottoming out in the block or getting inadequate thread engagement. This hardware kit eliminates that problem with bolts cut specifically for aluminum bellhousing installations behind TREMEC TKX transmissions.

The BOP bolt pattern -- shared by Buick, Oldsmobile, and Pontiac V8 engines from the mid-1960s forward -- differs from the more common Chevy pattern in its top bolt locations. This kit includes Grade 8 fasteners sized precisely for that pattern when paired with an aluminum bellhousing. The shorter bolt lengths account for the reduced thread depth available in aluminum compared to steel castings, ensuring proper engagement without bottoming out.

This kit covers the bellhousing-to-engine connection only. Transmission-to-bellhousing bolts are not included -- most bellhousing manufacturers supply those with the housing itself, or factory transmission mounting bolts can be reused. If you are running a steel bellhousing instead of aluminum, see MDL's steel bellhousing hardware kit for the correct bolt lengths.

What's Included

Description

Finding a quality flywheel for a Buick 300 engine can be a challenge. Stock cast iron units are heavy, prone to stress cracking under repeated heat cycles, and getting harder to source. This MDL lighten billet steel flywheel solves those problems with modern materials and precision manufacturing, giving you a durable, high-performance replacement that bolts right in.

Billet steel construction delivers significant advantages over cast iron flywheels. Machined from solid steel stock rather than poured into a mold, billet flywheels exhibit superior strength and are far less susceptible to the stress cracks that plague cast iron units over time. The alloy content and manufacturing process create a flywheel that handles higher torque loads and more aggressive clutch materials without the risk of catastrophic failure. For street-driven Buicks that see spirited driving or occasional track time, billet steel is the smart upgrade.

The zero balance design is purpose-built for the internally balanced Buick 300 engine architecture. Unlike externally balanced engines that require weighted flywheels, the Buick 300 uses a zero-balance flywheel that simplifies installation and eliminates concerns about weight migration at high RPM. The 160-tooth ring gear is the correct specification for Buick 300, 340, early 350, and 231/3.8L V6 applications, ensuring proper starter motor engagement.

At 27 pounds, this flywheel strikes a balance between reduced rotating mass and adequate inertia for smooth street driving. The 11-5/8" equal bolt pattern accepts 10.5" clutch assemblies, and the precision-machined 2.487" crank registration bore guarantees accurate crankshaft fitment.

Description

High-output GM builds often face a clutch dilemma: maximum holding power is required, but engine bay constraints prevent stepping up to a larger diameter disc. The Superior 11" Kevlar/Ceramic clutch set solves this problem by combining aggressive friction materials with a low lever height design specifically engineered for hydraulic concentric slave cylinder applications. The result is 600 lb-ft of torque capacity in a package that clears modern hydraulic release systems without binding or inconsistent pedal feel.

The dual-compound friction disc places Kevlar on the pressure plate side and ceramic on the flywheel side--a combination that delivers the best of both materials. Ceramic's higher coefficient of friction provides the hard-hitting bite needed for drag launches and quick shifts, while Kevlar contributes smoother engagement characteristics. The ceramic material contains iron particles that actually increase friction as temperatures rise, making this clutch thrive under sustained abuse in road course and strip conditions where lesser friction materials would fade.

Every Superior clutch disc is hand-assembled in MDL's facility to exacting tolerances. Double-riveted construction ensures the friction material stays put under repeated high-load cycles, while the sprung hub design absorbs driveline shock and smooths power delivery. The diaphragm-style pressure plate provides consistent clamping force across the entire disc surface. This clutch set fits GM bellhousing patterns with a 12-5/8" equalizer bolt pattern and mates to any 26-spline, 1-1/8" input shaft--including TREMEC TKX, TKO, and T56 Magnum transmissions.

Description

When you're building a hydraulic clutch system from scratch, piecing together individual components wastes time and often leads to compatibility headaches. MDL bundles this complete master cylinder kit for builders who want everything needed to install a hydraulic clutch master without hunting down fittings, rods, and hardware separately. The LF Series represents MDL's engineered approach to hydraulic clutch actuation - every component selected and tested to work together seamlessly.

This cylinder's 0.700-inch bore paired with a full 1.4-inch stroke delivers 0.540 cubic inches of displacement volume - the sweet spot for actuating most hydraulic throwout bearings and slave cylinders without over-pressurizing the system or requiring excessive pedal travel. Don't confuse this with the Wilwood GS that has a shorter stroke - MDL's full 1.4-inch stroke ensures complete clutch disengagement even with high-clamp-load pressure plates.

The remote reservoir design allows flexible mounting options when firewall space is limited or when you need to keep the fluid reservoir away from engine heat. All MDL hydraulic kits are hand-assembled in-house so that quality and tolerances can be controlled, then tested and double-checked for fit and finish before they go in the box. If you don't use the full stroke of the cylinder, MDL offers 3/4-inch and 7/8-inch bore masters for applications requiring different volume characteristics.

This universal kit works across Ford, GM/Chevy, and Mopar applications with stock clutch pedals or aftermarket reproduction pedals. Uses DOT 3 or DOT 4 brake fluid. Made in the USA with lifetime technical support available at 208-453-9800.

Description

Worn shift balls with faded graphics look cheap and undermine an otherwise clean build. This MDL 5-Speed Black Shift Ball solves that problem with subsurface graphics that are embedded below the polished surface - they physically cannot wear off, fade, or chip regardless of how many miles you put on the car or how aggressively you shift.

The ball is constructed from a specially formulated high-impact polymer resin developed specifically for automotive applications. Unlike generic plastics that crack and degrade with age and temperature cycling, this formulation resists stress cracking even after years of exposure to heat, cold, and UV light. At 4 ounces, the weight is calibrated to provide positive shift engagement without the excessive mass that can stress synchronizers or create unwanted momentum during quick shifts.

Inside, a brass or aluminum master insert provides the threaded mounting point and exceeds automotive industry specifications - tested to withstand 200 ft. lbs. of static pull force and 20 ft. lbs. of twist torque. The 3/8"-16 internal threading fits most domestic shifter applications, and MDL stocks thread adapters for virtually any shifter setup if your lever uses a different thread pitch. Each ball is precision machined and polished to a high-gloss finish that looks as good as it feels.

Made in the USA by a manufacturer that has been producing precision shift components since 1952, this shift ball delivers the quality and attention to detail that serious builds demand. Whether you are finishing a classic muscle car, a restomod, or a modern performance machine, the MDL logo and 5-speed pattern tell everyone you built it right.

Description

The shift knob is your primary connection point to the drivetrain during every gear change. This white 5-speed shift ball delivers the durability and feel you need with high-impact polymer resin specifically formulated for automotive applications. Unlike generic plastics that develop stress cracks over time from temperature cycling and repeated use, this material is engineered to handle real-world performance conditions.

The 1-7/8" diameter provides excellent grip surface and comfortable palm contact. The 5-speed shift pattern is applied subsurface, meaning the graphics are embedded within the material rather than printed on top -- they physically cannot wear off from years of shifting. The entire ball is precision machined and polished to a high-gloss finish that resists scratching and cleans easily.

At the core is a brass master insert machined to 16mm x 1.50 threading. This insert is tested to exceed automotive industry specifications: 200 ft-lbs of static pull and 20 ft-lbs of twist torque. Because the knob uses the common 16mm x 1.50 master insert, it accepts MDL's complete line of thread reducing inserts -- so you can adapt it to fit 3/8"-16, 3/8"-24, 5/16"-18, 12mm x 1.75, 10mm x 1.50, and other common shift lever thread sizes. If your shifter doesn't use 16mm x 1.50 threading, just add the appropriate reducer to make it work.

Weighing 4 ounces, this knob provides enough mass for positive shifting feedback without the excessive weight that can stress shift mechanisms or cause gear selection issues. Made in the USA with automotive-grade materials and quality craftsmanship.

Description

Slamming into reverse at speed is a quick way to grenade a gearbox. This 5-speed shift ball eliminates that risk with an integrated side-mounted push button lockout that requires deliberate activation before reverse can be selected. The button includes wiring for connection to various shifter configurations that utilize electronic or mechanical reverse lockout functionality.

The ball itself is built from specially formulated high-impact polymer resin designed specifically for the automotive industry. Unlike cheap plastic knobs that crack under stress or go chalky from heat cycles, this material resists stress cracking with age while handling the torque and temperature swings of hard driving. The 1-7/8" diameter provides solid palm contact for confident shifting, and the polished white finish cleans up easily.

Mounting uses a 16mm x 1.50 brass master insert with an included brass jam nut. This thread size is common on 1982-2002 Camaro and Firebird shifters, Pontiac Fiero applications, and various aftermarket shifters. For other thread sizes, pair this shift ball with MDL thread reducers to adapt down to your specific shifter requirements.

This 5-speed black shift ball puts a side-mounted momentary push button exactly where your thumb naturally rests, giving you instant access to nitrous activation, line lock, or other electrical accessories without fumbling for a dashboard switch or console button.

The side-mount placement is intentional: unlike top-mounted buttons that can be accidentally triggered during aggressive shifts, this configuration requires deliberate engagement. The included 18" wire harness gives you plenty of length to route to your relay or control module, with terminals ready for connection. Whether you're staging at the strip or wiring in a secondary system, the button is right there when you need it.

Built from black polymer resin, this 2-1/8" diameter shift ball delivers comfortable ergonomics for extended driving sessions while standing up to the abuse of street and track duty. The 16mm x 1.5 threads are the industry-standard size for shift knob adapters, which means you can pair this ball with MDL's thread reducing inserts to fit virtually any shift lever thread pitch -- from 3/8"-16 to 5/16"-18 and beyond.

Description

This is the shift lever that defined an era. The Hurst chrome-plated round bar stick was the upper bolt-on stick originally supplied from Detroit factories for vehicles that were "Hurst Equipped." The chrome round bar design, bolt-on construction, Hurst logos, and white ball knob were the identifying features that signified a Hurst shifter was installed at the factory as original equipment. For years, these OEM round bar sticks were never sold to the general public - they were only available if you bought a vehicle optioned with a Hurst shifter from the dealer.

Now this OE-style stick is available directly from Hurst, with all the great features exactly as originally designed. Built from forged steel with high-quality chrome plating, this shift lever delivers the authentic look and durability that made Hurst "America's Number 1 Shifter Company." The iconic "HURST" name is stamped directly into the stick, providing the period-correct detail that separates genuine Hurst hardware from generic alternatives.

The 11.21-inch height with 3.75-inch setback creates the classic curved geometry that puts the shift knob exactly where it belongs for smooth, confident shifts. This lever is particularly popular for 1969 Camaro and Firebird builds, fitting factory console installations as well as period-correct Muncie 4-speed shifters. Modern builders will appreciate that it also works perfectly with TREMEC TKX, TKO, and T56 Magnum transmissions paired with Hurst-pattern shifter mechanisms.

The universal 3/8"-16 TPI thread accepts all Hurst shift knobs and T-handles, giving you complete control over the final appearance. Whether you're completing a concours-level restoration or building a restomod that honors classic muscle car heritage, this chrome round bar shift lever delivers the authentic Hurst experience.

• Direct fit for Ford T5, T45, TKO, TKX, and T56 Magnum transmissions
• Precision-molded construction for smooth, reliable operation

Description

When you swap to a 5- or 6-speed transmission, your original speedometer gear won't work with the new final drive ratio, throwing off your speedometer readings. This 16-tooth driven gear provides the correct gear ratio match to restore accurate speedometer operation in Ford T5, T45, TKO, TKX, and T56 Magnum applications.

Selecting the correct driven gear depends on your rear axle ratio and tire diameter. The wine-colored housing provides instant visual confirmation of the 16-tooth count during installation and future service, eliminating guesswork when fine-tuning your speedometer calibration. Each tooth change adjusts the speedometer reading approximately 4-5 mph, so selecting the right gear for your combination is critical.

This is the correct driven gear for all Ford T5, T45, TKO, TKX, and T56 Magnum transmissions. Whether you're building a street machine that sees daily driving or a weekend cruiser that needs reliable instrumentation, this precision-molded gear delivers smooth, accurate speedometer operation mile after mile.

What's Included

• 16-tooth speedometer driven gear with wine-colored housing

Key Features

• 17-tooth driven gear with white color coding for easy identification
• Direct fit for Ford TREMEC transmissions: T5, T45, TKO, TKX, and T56 Magnum
• Precision-molded plastic construction for smooth, quiet operation
• Lower tooth count for higher axle ratios and/or taller tires
• Works with cable-driven mechanical speedometer systems

Description

Swapping to a 5 or 6-speed TREMEC transmission changes your final drive ratio, which means your factory speedometer gear combination no longer reads accurately. This 17-tooth white driven gear lets you recalibrate your mechanical speedometer to match your new drivetrain setup.

Speedometer driven gear selection depends on four variables: drive gear tooth count (on the output shaft), driven gear tooth count, tire diameter, and axle ratio. The 17-tooth count is typically paired with lower-numerical axle ratios or taller tires. Use a speedometer gear calculator to determine the correct tooth count for your specific combination of drive gear, rear end ratio, and tire height.

The white color coding makes this gear instantly identifiable, both in your parts bin and during installation. This precision-molded plastic gear meshes smoothly with the transmission's output shaft drive gear, delivering reliable operation without the noise or wear issues that can plague poorly-manufactured replacements.

This driven gear fits all Ford TREMEC transmissions including T5, T45, TKO, TKX, and T56 Magnum. Whether you're building a classic Mustang, Fairlane, or any Ford platform with a mechanical speedometer, this gear helps dial in accurate speed readings after your manual transmission conversion.

• Yellow color-coded for quick identification during installation and service
• Fits Ford T5, T45, TKO, TKX, and T56 Magnum transmissions
• Precision molded for accurate tooth engagement and long service life
• Direct replacement--installs into existing speedometer drive housing without modification

Description

When you swap in a 5- or 6-speed manual transmission, your factory speedometer gear ratio goes out the window. The new transmission's final drive ratio won't mesh with your original speedo gear, leaving your speedometer reading inaccurately--sometimes wildly so. This 18-tooth yellow driven gear lets you dial in the correct speedometer calibration for your specific tire size and rear axle ratio combination.

This driven gear fits the full range of Ford-pattern TREMEC transmissions: T5, T45, TKO, TKX, and T56 Magnum. The industry-standard yellow color coding makes identification simple--no guessing which tooth count you're running when it's time for service or recalibration after a gear ratio change. The precision-molded construction ensures consistent tooth engagement with the drive gear for accurate, reliable speedometer readings mile after mile.

Installation is straightforward--the gear slides directly into the transmission's speedometer drive housing. If your speedometer calibration calculations call for more than 21 teeth (the maximum available driven gear size), you'll need to reduce the drive gear tooth count instead. Use a speedometer gear calculator with your tire diameter, axle ratio, and transmission drive gear tooth count to determine the correct driven gear for your application.

Kit Includes

• 18-tooth yellow speedometer driven gear

Key Features

• 19-tooth driven gear for precise speedometer calibration
• Pink color-coded for instant tooth count identification
• Fits Ford T5, T45, TKO, TKX, and TREMEC T56 Magnum transmissions
• Essential for correcting speedometer accuracy after gear ratio or tire size changes
• Precision molded construction for reliable, long-lasting operation

Description

When you swap transmissions, change rear axle ratios, or bolt on different tire sizes, your speedometer no longer reads correctly. This 19-tooth driven gear lets you recalibrate for accurate readings by changing the gear ratio between your transmission's output and the speedometer cable. It's the driven gear -- the one that mounts to the speedometer cable end and inserts into the transmission tailhousing.

The pink color follows Ford's standardized identification system, making it easy to confirm the tooth count at a glance when you're sorting through your parts bin or comparing against your current setup. If your speedometer reads too fast with your current gear, stepping up to this 19-tooth unit will slow the reading. Each additional tooth changes the speedometer reading by approximately 5-6%. If you need an even higher tooth count, 21-tooth is the largest available in the driven gear; beyond that, you'll need to reduce the drive gear size instead.

This gear fits all Ford T5, T45, and Ford T56 transmissions, as well as all TREMEC TKO, TKX, and T56 Magnum units. Installation is straightforward: remove the speedometer cable from the tailhousing, swap the driven gear, and reinstall.

What's Included

• One 19-tooth speedometer driven gear (pink)

Key Features

• 20-tooth driven gear for precise speedometer calibration
• Black color-coded for easy identification per Ford specification
• Fits Ford T5, T45, Ford T56, TREMEC T56 Magnum, TKO, and TKX transmissions
• Direct replacement for worn or incorrect factory gears
• Precision-molded plastic construction for durability and accurate engagement

Description

Transmission swaps and axle gear changes throw off speedometer accuracy - this 20-tooth driven gear gets your needle reading true again. When you install a five- or six-speed manual, the final drive ratio no longer matches your original speedometer gear, leaving you guessing at your actual speed. The correct driven gear restores accurate instrumentation so you know exactly how fast you're going.

This precision-molded driven gear is color-coded black for 20-tooth identification, following the standard Ford speedometer gear system. It pairs with the 7-tooth drive gear found on TREMEC TKO 500, TKO 600, TKX, and T56 Magnum transmissions to dial in speedometer accuracy for specific tire and axle combinations. Calculate your correct tooth count based on your tire diameter and rear axle ratio - if your math points to 20 teeth, this is your gear.

Note that 21 tooth is the largest driven gear size available for these applications. If your calculations call for a larger tooth count beyond 21, reducing the drive gear size provides the necessary calibration adjustment. Compatible with all Ford T5, T45, Ford T56, TREMEC T56 Magnum, and all TKO and TKX variants.

What's Included

• One 20-tooth driven speedometer gear (black)

Key Features

• 21-tooth red gear follows Ford's factory color-coding system for manual transmissions

Description

Swapping to a 5 or 6-speed TREMEC transmission changes your final drive ratio, which throws off your factory speedometer calibration. This 21-tooth red driven gear lets you recalibrate your mechanical speedometer to read accurately with your specific tire size and rear axle ratio combination--no electronic tuner required.

Ford has used a consistent color-coding system for manual transmission speedometer gears since the 1960s: 16-tooth wine, 17-tooth white, 18-tooth yellow, 19-tooth pink, 20-tooth black, and 21-tooth red. As the largest tooth count in the standard range, this red 21-tooth gear provides maximum correction for applications with taller tires or numerically higher axle ratios. Each tooth of difference adjusts your speedometer reading approximately 5-6%, so selecting the correct count is critical for accuracy.

The driven gear installs into the speedometer housing on the tailshaft of your transmission, where it meshes with the drive gear on the output shaft. TKO, TKX, and T56 Magnum transmissions come from the factory with a 7-tooth drive gear, making this 21-tooth driven gear the correct starting point for common combinations like 3.55 or 3.73 rear gears with 26-inch or taller tires. Use a speedometer gear calculator with your actual tire diameter and axle ratio to confirm the correct tooth count for your build.

This gear is compatible with Ford T5, T45, TKO, TKX, and T56 Magnum transmissions. The driven gear works with both cable-driven and VSS-equipped speedometer systems--just swap it into your existing housing.

What's Included

• 21-tooth red speedometer driven gear (precision molded nylon)

Key Features

• Secures driven speedometer gear for proper placement and operation in Ford T5 transmissions
• Direct replacement for original clips that have become brittle from heat exposure
• Essential component for automatic-to-manual conversions where no clip exists
• Compatible with all Ford T5 transmissions

Description

Clip-style speedometer gears require a retaining clip to lock the driven gear securely in the transmission housing, and this replacement clip delivers the secure fit your Ford T5 needs. Without a properly functioning clip, the driven speedometer gear can back out of the housing during operation, causing inaccurate speedometer readings and potential fluid loss.

Original retaining clips often become brittle after years of heat cycling in the transmission environment. If you're servicing your Ford T5, T-45, T-56, TKO/TKX, and Magnum speedometer gear or coming from an automatic transmission that didn't use a mechanical speedometer setup, a new retaining clip ensures your driven gear stays exactly where it needs to be. This is an inexpensive detail that makes the difference between a speedometer that works reliably and one that gives you trouble down the road.

This clip is the correct fitment for all Ford T5 transmissions and works with standard Ford-style driven speedometer gears. Keep one on hand whenever you're doing speedo gear service work.

What's Included

• One (1) retaining clip for Ford driven speedometer gear

Key Features

• 16-pulse Hall effect sensor delivers 16,000 pulses-per-mile output for accurate electronic speedometer calibration
• Direct bolt-in fitment for Ford gear drive TKO and TKX transmissions
• Three-wire design with included 10-foot pigtail harness for flexible routing and clean signal transmission
• Allen-head mounting bolt provides body clearance in tight transmission tunnel applications
• Uses standard T5 driven speedometer gears - no adapter required for low-profile installation.
• Compatible with Ford T-5, T-45, TR3550, 5-speed and 6-speed Ford T-56, and Magnum transmissions (requires Ford-driven speedometer gears and retainer clip)

Description

Swapping to a TKO or TKX five-speed means ditching the factory mechanical speedometer cable - but your electronic dash, engine management system, or cruise control still needs a reliable speed signal. This digital speedometer sensor plugs directly into the Ford-style VSS port on your TREMEC transmission's passenger-side tail housing and delivers a clean 16-pulse signal that works with the industry-standard 16,000 pulses-per-mile input most aftermarket speedometers and ECUs expect.

The three-wire Hall effect design provides a stable square wave output that won't degrade over long wire runs. The included 10-foot pigtail harness gives you plenty of length to route wiring cleanly through the tunnel and up to your dash or ECU, with a three-pin connector for easy hookup. The Allen-head mounting bolt is a thoughtful detail - standard hex-head fasteners can interfere with the sensor body in tight quarters, so this design ensures proper installation without clearance issues.

Beyond the TKO and TKX, this sensor also works with T-5z 5-speed and 6-speed Magnum transmissions when paired with Ford-driven speedometer gears and a retainer clip. Note that it does not fit Super Magnum, Magnum XL, or Magnum F transmissions - those use a different VSS configuration. If you're running a Dakota Digital, Classic Instruments, Auto Meter, or other programmable electronic speedometer, this sensor's 16,000 PPM output drops right into their standard calibration range.

What's Included

• 16-pulse digital speedometer sensor with three-pin connector

Description

Upgrading to a TREMEC transmission puts serious torque capacity in your drivetrain, but your existing slip yoke often becomes the weak link. TREMEC TKO, TKX, and Magnum transmissions all feature a 31-spline output shaft that requires a matching slip yoke to handle the increased power these transmissions deliver. This MDL slip yoke solves that problem with cast steel construction and 1350 series U-joint capacity.

The 31-spline output shaft on TREMEC performance transmissions uses the same diameter as Ford C6 automatics—a proven design that has been handling serious torque for decades. The 1350 series U-joint provides a 1-3/16" cap diameter and 3.625" overall width, delivering significantly more strength than the smaller 1310 series joints found in many factory drivelines. When you're pushing 600 lb-ft of torque capacity through a TKO or TKX, you need driveline components that can keep up.

This slip yoke is designed for Ford applications but works with any TREMEC transmission featuring the standard 31-spline output shaft, including the TKO-500, TKO-600, TKX, and T56 Magnum. Whether you're building a street machine that sees weekend abuse or a dedicated track car, this yoke provides the strength and reliability your upgraded drivetrain demands.

Description

Converting to a modern TREMEC transmission demands a slip yoke that won't become the weak link in your drivetrain. Factory cast yokes are prone to spline twisting and failure under the torque output of high-performance engines. This Sonnax forged chromoly slip yoke is engineered to handle serious power without compromise, making it the go-to upgrade for street, strip, and track applications.

Sonnax slip yokes are forged, not cast, for greater strength, and they undergo a precision-machining process to guarantee exceptional balance and minimal runout. The 1350 series U-joint capability provides a significant strength upgrade over 1330 applications--crucial for builds pushing serious horsepower. With a 3-5/8" U-joint width and 1-3/16" caps, the 1350 series delivers the torque capacity needed for modern high-output engines.

Every yoke is 100% leak-tested with the seal plug O.D. ground for superior seal, then air-tested to 40 psi to ensure optimum sealing. The smooth outer journal ensures uniform contact with the transmission seal, preventing leaks while promoting proper slip action during suspension travel. This attention to detail eliminates the fluid weeping common with lesser yokes.

This 31-spline configuration directly fits TREMEC TKX, TKO-500, TKO-600, and T56 Magnum transmissions, as well as Ford C6 and FMX automatics, Ford Toploader 4-speeds, and ZF 5-speed transmissions.
