Overview

If you are making over 400 horsepower and need to upgrade from a tired four-speed, the TREMEC TKX delivers everything your Ford build demands. Unlike repurposed OE transmissions, the TKX was engineered from the ground up specifically for the aftermarket - designed to handle serious power while fitting into classic Mustangs and other vintage Fords without the floor surgery typically required by larger transmissions.

The end-loaded case design is the key to the TKX's compact footprint. TREMEC eliminated the traditional side-loading architecture, resulting in a slimmer, more streamlined case that clears tight transmission tunnels. The three-piece ribbed aluminum housing (main case, intermediate plate, and rear extension) delivers outstanding structural stiffness while reducing overall weight to just 99 lbs dry. Fewer case seams mean fewer potential leak points, and gaskets at all flanges simplify installation.

Inside, the TKX punches well above its weight class. Wide gear widths increase gear life and torque capacity, while tapered roller bearings on the input, output, and countershafts reduce noise and improve durability. Caged needle bearings on the mainshaft optimize performance at all gear positions. The internal three-rail shift system provides robust, precise gear engagement, and the rear mainshaft support bushing has been relocated closer to the gearbox for improved support. Hybrid triple-cone synchronizers made from sintered bronze and carbon deliver smooth, notch-free shifts even at 7,500 RPM.

This close-ratio configuration (2.87 first gear with 0.68 overdrive) keeps your engine in its powerband during spirited driving while dropping highway RPM for improved fuel economy and reduced wear. Short input shaft kits are available for Ford 3-speed and 4-speed bellhousing applications. Made from 100% brand-new OEM-quality components.

Description

Factory T-5 and stock Ford transmission hardware won't work when you're bolting a TREMEC TKX to a modular aluminum bellhousing - the bolt lengths are simply wrong for the application. This dedicated hardware kit solves that problem by providing transmission-to-bellhousing bolts engineered specifically for the aluminum bellhousing interface found on Ford modular engine conversions.

Why does bellhousing material matter for bolt selection? Aluminum bellhousings have different flange thicknesses than their steel counterparts, requiring specific bolt lengths to achieve proper thread engagement without bottoming out. Using the wrong hardware risks either inadequate clamping force or mechanical interference - neither of which you want in a drivetrain connection.

This kit is designed to complement Ford modular aluminum bellhousings (like the Ford Performance M-6392-M46) when paired with a TREMEC TKX transmission. Note that some bellhousing manufacturers include transmission-to-bellhousing bolts with their bellhousing - in those cases, this kit provides the remaining hardware your installation requires. If you're running a steel bellhousing, see our steel bellhousing hardware kit instead.

What's Included

• Transmission-to-bellhousing mounting bolts (aluminum bellhousing specific lengths)

Key Features

• Bolt lengths sized specifically for steel bellhousing applications - not interchangeable with aluminum bellhousing hardware
• Grade 8 steel construction for maximum clamping force and durability
• Hardened washers included for proper load distribution across mounting surfaces
• Complete hardware set for attaching Ford TKX transmission to steel bellhousings
• Compatible with QuickTime and Lakewood steel scatter shields for Ford applications
• Made in the USA

Description

When upgrading to a TREMEC TKX 5-speed transmission, factory T5 transmission-to-bellhousing bolts are incompatible with TKX applications. This hardware kit provides the correct bolt lengths and grade specifically engineered for steel bellhousing installations on Ford applications. Steel bellhousings require different bolt lengths than aluminum bellhousing kits - using the wrong hardware can result in improper engagement, case damage, or unsafe mounting conditions.

This MDL hardware kit solves the sourcing headache by providing the exact fasteners needed for your steel bellhousing installation. The Grade 8 bolts deliver the clamping force necessary to handle the TKX's 600 lb-ft torque capacity, while hardened washers ensure even load distribution across the bellhousing mounting flange. Proper hardware is critical - never use transmission-to-bellhousing bolts to draw or pull the transmission up to the bellhousing, as damage to the pilot bearing and transmission case ears may result.

This kit is designed for use with popular steel scatter shields including QuickTime and Lakewood bellhousings for Ford small block applications paired with the TKX transmission. When installing, ensure the transmission is fully seated by hand against the bellhousing before torquing fasteners to specification. Made in the USA with lifetime tech support from MDL.

Description

When your build pushes past 500hp and you still want to drive it on the street, single-disc clutches start showing their limits. The McLeod RXT twin disc clutch kit delivers 1,000hp holding capacity in a package that maintains street manners - soft pedal effort, smooth engagement, and the kind of durability that lets you drive to the track, run quarter-mile passes, and drive home without drama.

The engineering centers on dual ceramic friction discs mounted to a Blanchard ground floater plate. The ceramic facings provide slightly aggressive engagement with excellent release characteristics - enough grip for serious power without the on-off grabbiness that makes some racing clutches miserable in traffic. The floater plate distributes heat across both friction surfaces, preventing the hot spots that kill single-disc setups under sustained abuse. McLeod's diaphragm pressure plate maintains consistent clamping force throughout the disc's lifespan while actually delivering lighter-than-stock pedal effort.

This kit uses McLeod's patent-pending large gold metric adapter ring, eliminating the need for a dedicated flywheel. The adapter ring bolts directly to flat-style metric flywheels found on Ford 164T Modular engines (4.6L, 5.0L Coyote, 5.4L) and GM 168T LS1/LS6 applications. Critical note: this kit will NOT fit factory 2011-17 Coyote flywheels, recessed LS2/LS3/LS7 flywheels, or flywheels with crank reliefs larger than 6.250 inches in diameter. The 1-1/8-inch x 26-spline input shaft fits T-45, TR-3650, T-56, TR-6060, and TREMEC Magnum transmissions with 26-spline inputs.

Break-in requires 500-750 miles of stop-and-go city driving to properly seat the friction surfaces - no drag racing or dyno pulls until you've actuated the clutch 1,200-1,500 times. Always resurface the flywheel with a coarse stone-ground finish, replace the pilot bearing, and verify bellhousing alignment during installation. This kit does not include a pilot bearing or throwout bearing.

What's Included

Description

When your Ford 4.6L or 5.0L modular engine is making serious power, OEM-style clutches and their stamped steel pressure plates become the weak link. The Tilton ST-246 was designed from the ground up as a true performance twin-disc clutch -- not an OEM-type stamped steel pressure plate with a floater tacked on. Tilton Engineering has been the leading supplier of small-diameter racing clutches since 1972, winning championships in F1, NASCAR, IMSA, IndyCar, SCCA, Formula Drift, and SCORE. That racing pedigree is engineered directly into this street-capable assembly.

The aluminum clutch cover shares technology from Tilton's championship-winning OT-Series racing clutches, delivering superior strength and stiffness compared to stamped steel alternatives. The high-mass pressure plate and floater plate are machined from the same proprietary materials used in Tilton's racing clutches, providing exceptional heat capacity and warpage resistance under sustained high-torque loads. The floater plate is twice the thickness of most competing twin-disc designs, which allows for the sprung-hub disc configuration, eliminates gear chatter, and provides dramatically better heat dissipation. Heavy-duty straps connecting the plates to the cover eliminate the noise and inconsistent engagement plaguing lesser twin-disc designs.

This assembly's dual 246mm organic discs with sprung center hubs deliver 850 lb-ft capacity while dampening engine vibrations and reducing gearbox noise for smooth street engagement. The chromoly steel flywheel features an integrated 164-tooth ring gear and precision register that locates the clutch for optimal balance -- a critical upgrade over the loose-fitting bolts and dowels used with stamped steel clutches. The result is a clutch system that handles serious power while maintaining street manners.

Fits Ford 4.6L and 5.0L modular engines with 8-bolt crank flanges. The 26-spline x 1-1/8-inch hub works with TREMEC TKO, TKX, T56 Magnum, and Magnum XL transmissions. Note: TREMEC transmission models 11010, 11011, and 16884 require the guide tube to be trimmed 0.5 inches to prevent disc interference. Magnum XL applications require hydraulic kit MD-900-2505-A, hose, and fitting (sold separately). Does not include pilot bearing or throwout bearing. Made in the USA.

Description

When you're pushing serious power through a Ford modular engine and need clutch engagement that won't slip under load, you don't compromise on components. This Tilton ST-246 twin-disk assembly delivers 1250 lb-ft of holding power with the precise, positive engagement characteristics that high-horsepower street/strip applications demand. Unlike stamped steel performance clutches that simply add a floater plate as an afterthought, the ST-246 was engineered from the ground up as a true twin-disk clutch system.

The precision-machined aluminum pressure plate cover incorporates technology proven in Tilton's championship-winning OT-Series racing clutches, providing superior strength, stiffness, and dynamic balance compared to OEM-type stamped steel covers. The high-mass pressure plate and floater plate are machined from the same proprietary materials used in Tilton's motorsport applications—delivering exceptional heat capacity and warpage resistance under hard use. The floater plate is twice the thickness of most twin-disk competitors, which allows for the solid hub construction while eliminating gear clatter and providing superior heat dissipation.

The cerametallic discs feature solid center hubs for maximum strength and positive engagement—essential for high-horsepower applications where precise modulation matters more than street comfort. Heavy-duty straps attach both the pressure plate and floater plate to the aluminum cover, minimizing noise and providing fast, clean release between shifts.

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

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
• Largest standard driven gear tooth count available for maximum speedometer correction
• Fits all TREMEC transmissions using Ford-style speedometer systems: T5, T45, TKO, TKX, and T56 Magnum
• Precision molded nylon construction for smooth, quiet operation and long service life
• Direct drop-in replacement--no modifications required

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.

Description

Modern manual transmissions feature complex internal components -- multiple gear sets, clutch packs and narrow oil passageways -- that demand a steady supply of high-quality fluid to function properly. Without it, wear and sludge formation can lead to reduced performance and even catastrophic failure requiring thousands of dollars in repairs. This AMSOIL Synthetic Automatic Transmission Fluid delivers the Dexron III specification required by TREMEC transmissions while providing protection that exceeds conventional fluids.

In both normal and severe service, this synthetic ATF resists wear to the transmission's valve body, gears, clutch plates and synchronizers, helping your TREMEC achieve long service life. The thermally stable formulation guards against the harmful effects of thermal breakdown in elevated heat conditions, while resisting heat-related evaporation and viscosity loss to keep internal components clean and protected.

Formulated with friction modifiers that promote fast, smooth clutch engagement, this fluid delivers responsive shift feel and efficient torque transfer. It remains fluid in sub-zero temperatures, resisting thickening and flowing quickly for reliable shifts during cold starts. The excellent low-temperature fluidity also maximizes fuel efficiency. Seal conditioners help guard against leaks at input shaft seals and other critical points.

TREMEC TKX transmissions use Dexron III or Dexron III/Mercon specification ATF fluid, and Dexron III ATF is also recommended for T56 and TR3650 models. The T5, TKO and TKX five-speed transmissions require approximately 2.75 quarts, while six-speed Magnum transmissions require approximately 3.45 quarts. TREMEC recommends changing fluid after the initial 500-1000 mile break-in period, then every 30,000 miles thereafter.

What's Included

• One (1) quart bottle AMSOIL Synthetic Automatic Transmission Fluid (Dexron III compatible)

Description

When you swap a T56 Magnum 6-speed into your SN95 Mustang, your factory driveshaft no longer fits - the Magnum's 31-spline output shaft requires a matching slip yoke, and the transmission's positioning changes your overall driveline length. This custom steel driveshaft solves both problems with a purpose-built assembly designed specifically for 1996-2004 Mustangs running T56 Magnum transmissions.

The driveshaft is built around a DOM seamless 3.0" steel tube that's 15% stronger than OEM construction. DOM (Drawn Over Mandrel) tubing delivers consistent wall thickness and superior concentricity compared to standard welded tubing, which translates to better balance characteristics and increased strength under load. The 31-spline forged steel slip yoke slides directly onto the T56 Magnum's output shaft, while 1330 series U-joints provide the proven torque capacity needed for high-performance street and strip use.

Every driveshaft is professionally high-speed balanced to eliminate the vibration issues that plague improperly built assemblies - critical when you're putting power through a 700 lb-ft-rated transmission. The 44.3" center-to-center measurement is precision-cut for the SN95 chassis, and the rear flange bolts directly to Ford 8.8 small flange rear ends with the 2" center bolt pattern. A black painted finish provides long-term corrosion protection.

This is a custom-built driveshaft - you'll need to submit the MDL driveshaft build sheet with your vehicle measurements to info@moderndriveline.com before your shaft is built. SVT models require individual measurements due to chassis variations. Made in the USA with lifetime technical support.
