Description

Need overdrive performance in a tight engine bay? The TREMEC Super Duty T5 is the answer. As the smallest and lightest transmission in the TREMEC lineup, it fits where others simply cannot - making it the go-to choice for classic car retrofits, hot rods, and kit cars where space is at a premium. At just 75 lbs dry weight, you get 5-speed capability without the bulk of larger transmissions.

This Z-specification unit represents a significant upgrade over the original equipment T5s found in '83-'93 Mustangs. Where the '83-'84 non-World Class units ran a 2.95 first with 0.63 overdrive but suffered from weaker synchronizers, and the '85-'93 World Class versions switched to a 3.35 first with 0.68 overdrive, the Super Duty combines the best of both worlds: the preferred 2.95/0.63 gear set with World Class internals including carbon fiber synchro rings on gears 1-4, tapered carrier bearings, and main needle bearings. The steel front bearing retainer and Cobra-style pocket bearing eliminate common failure points that plagued earlier designs.

The 2.95 first gear provides strong acceleration off the line, while the deep 0.63 overdrive significantly reduces highway RPM - cutting noise, heat, and wear while improving fuel economy. This transmission safely handles 330 ft-lb of torque and is suitable for street cars up to 450 horsepower on DOT-approved tires. It serves as a direct replacement for 1983-1993 V8 Mustangs and is ideal behind any small-block Ford engine, or as an upgrade for inline-four and six-cylinder applications. Requires 2.75 quarts of ATF Dexron III fluid.

For 1994-1995 5.0L V8 Mustangs or 1994-1998 3.8L V6 Mustangs, see part number MD-552-0251-94 for the SN95 version with longer input shaft.

Description

When you're building a high-revving Ford small block, your flywheel needs to handle the abuse without becoming a liability. Cast iron flywheels can crack under stress, and non-certified components may not meet the safety standards required at the track. This SFI certified billet steel flywheel delivers the strength and peace of mind that serious builds demand - meeting the rigorous testing standards established by the SFI Foundation for replacement flywheels and clutch assemblies.

The billet steel construction provides superior tensile strength compared to cast alternatives, resisting the centrifugal forces that tear lesser flywheels apart at high RPM. The lightweight design reduces rotating mass for quicker throttle response and faster revs, while maintaining enough thermal mass for consistent clutch engagement. Zero balance (internal balance) simplifies installation on Ford 289, 302, 351W, and 351C engines that use internally balanced rotating assemblies.

Versatility is built into the design with dual clutch bolt patterns. The 10" long pattern accepts 5/16" pressure plate bolts, while the 10.4" metric pattern uses 8mm bolts - and the metric alignment pins come pre-installed so you're ready for either setup. The 6.00" clutch damper counter-bore provides proper clearance for diaphragm-style pressure plates. Note that 157-tooth flywheels require a 3/4" offset starter (often labeled as "automatic" in parts catalogs) for proper ring gear engagement.

Manufactured in the USA with US-milled steel, this flywheel delivers the quality and consistency that American craftsmanship is known for. Whether you're building a weekend warrior or a dedicated track car, SFI certification means this flywheel meets the standards required by most sanctioning bodies for competition use.

Overview

Factory cast iron flywheels have their limits. At high RPM or under aggressive clutch clamping loads, they can develop stress cracks that compromise both performance and safety. This lighten billet steel flywheel replaces that weak link with a material that's fundamentally stronger—billet steel resists cracking and remains stable under the demands of performance driving.

The "lighten" designation refers to strategic material removal that reduces rotational mass without sacrificing structural integrity. At 19 lbs, this flywheel strikes the sweet spot between weight reduction and street manners—light enough for improved throttle response and quicker revs, yet heavy enough to maintain smooth idle characteristics and prevent the stalling issues common with ultra-lightweight aluminum units. The result is a flywheel that feels responsive on throttle tip-in while still delivering civilized behavior in traffic.

Dual clutch bolt patterns machined into the friction surface eliminate fitment guesswork, accepting both 10" and 10.5" pressure plates. The 157-tooth ring gear and 28oz external imbalance match OE specifications for pre-December 1982 small block Fords, ensuring proper starter engagement and crankshaft balance. This flywheel fits Ford 289, 302, and 351W Windsor engines, plus Ford Racing 363ci and 427ci stroker crate motors that use the 28oz balance specification.

Six-bolt crankshaft mounting provides secure attachment, while included clutch alignment pins ensure proper disc positioning during installation. Every flywheel is precision-machined from US-milled steel and manufactured in the USA.

Description

Cast iron flywheels can't handle serious RPM or the repeated abuse of high-horsepower launches. This billet steel flywheel is precision CNC-machined from certified steel, engineered to survive the stress levels that crack and shatter cast units. At 19 pounds, it sheds significant rotating mass compared to heavy OEM flywheels -- translating to quicker revs, faster deceleration between shifts, and reduced parasitic drag on the crankshaft.

The 28oz external balance is critical: all Ford 221, 260, 289, 302, and 351W engines built before December 1982 use a 28-ounce offset balance. Mismatch the balance weight and you'll introduce severe harmonic vibration that punishes bearings and shortens engine life. Post-1981 5.0L High Output engines switched to a 50oz balance -- this flywheel is not for those applications. Match your balance weight to your engine's build date, not the vehicle year.

The dual bolt pattern accommodates both 10" and 10.5" clutch assemblies, giving you flexibility when selecting or upgrading your pressure plate without swapping flywheels. The 157-tooth ring gear is the standard configuration for most small block Ford manual transmission applications in vintage Mustangs, Falcons, Fairlanes, and similar platforms.

Description

Factory cast iron flywheels become the weak link when you push serious power through a 5.0L Windsor. Cast iron is prone to stress cracking under repeated high-RPM clutch engagement, and a cracked flywheel at speed is a catastrophic failure waiting to happen. This lightened billet steel flywheel delivers the strength needed for high-performance street builds and competition use while shaving weight to improve engine response.

Billet steel is considerably stronger than cast iron and remains free of the stress cracks that plague factory flywheels under heavy use. The lightened design reduces rotational mass compared to standard-weight flywheels, allowing faster throttle response on acceleration and quicker RPM drop on deceleration - a noticeable improvement whether you're rowing through gears on the street or chasing lap times. The 50oz external balance matches factory 5.0L engine specifications for 1981-1995 applications, ensuring smooth operation with no vibration.

The dual clutch pattern provides flexibility in clutch selection, accepting both 10.5" metric diaphragm pressure plates and 10" long-style setups. Metric alignment pins come pre-installed to ensure proper clutch disc centering during installation. Note that diaphragm clutches require metric pressure plate bolts (MD-403-2003 or MD-403-2003ARP), while the 10" long pattern uses 5/16" bolts (MD-403-2004).

Engineered for Ford small block Windsor engines with 157-tooth starter ring gear applications. Fits all 1981-1995 Ford 5.0L engines requiring 50oz external balance. Proudly made in the USA using US-milled billet steel.

Description

Shed rotational mass without sacrificing reliability. This lightweight aluminum flywheel weighs just 19 lbs compared to heavy cast iron units, helping your engine reach higher RPMs quicker due to reduced rotating mass. That reduced inertia translates to improved throttle response and acceleration - the engine spends less energy spinning up the flywheel and more energy putting power to the wheels.

The riveted steel clutch facing provides superior heat dissipation and wear characteristics compared to bonded surfaces. Unlike cheaper aluminum flywheels that use pressed-on ring gears, this 157-tooth steel ring gear is mechanically fastened to the flywheel body, preventing the ring gear separation failures that can occur under high-stress conditions. The dual bolt pattern accommodates both vintage 10" Long-style and modern 10.4" metric pressure plates with dowel pins - eliminating compatibility guesswork across Ford's clutch evolution.

Engineered specifically for Ford small block 289, 302, and 351W Windsor engines, this flywheel comes standard as zero balance for internally balanced engines. For externally balanced applications, 28 oz or 50 oz counterweight options are available to match your specific crankshaft requirements - pre-1981 302s and all 351Ws use 28 oz imbalance, while 1981+ 302/5.0L engines require 50 oz.

Note: Aluminum flywheels spin up faster but have less stored energy than cast iron, which can make the engine easier to stall at low RPMs. If paired with a dual clutch set, this helps offset some of the characteristics. Aluminum flywheels should never be paired with ceramic or bronze clutches due to the added heat they generate. It is recommended to warm the flywheel before installing on the crank. Not SFI approved - intended for street performance and moderate competition use. Made in the USA with lifetime technical support.

• Made in the USA

Description

Ditch the heavy factory cast iron flywheel and drop serious rotating mass from your Ford small block. This aluminum flywheel delivers the weight reduction performance builds demand while maintaining the durability street engines require. Lighter rotating mass means quicker engine response and faster acceleration through the gears - your engine revs up and recovers faster between shifts.

The engineering here focuses on heat management and longevity. The riveted steel clutch facing provides a durable friction surface that handles heat far better than aluminum-on-aluminum contact, preventing warping and premature wear in spirited driving. The high-carbon steel ring gear is riveted to the aluminum body rather than pressed or shrunk on - this prevents the ring gear from walking off the flywheel under the repeated thermal cycling and shock loads of hard use.

This flywheel carries the correct 28oz external balance for pre-1981 Ford 289 and 302 engines, as well as all 351 Windsor engines regardless of year. The 157-tooth ring gear is sized for small bellhousing applications - the compact aluminum bellhousing, not the larger cast iron 164-tooth style. Includes dowel pins for proper clutch alignment with 10.5-inch diaphragm clutch kits.

Installation note: It is recommended to warm the flywheel before installing on the crankshaft for proper thermal expansion and fit. Aluminum flywheels should not be paired with ceramic or bronze-faced clutch discs due to the excessive heat these materials generate. Made in the USA.

What's Included

• Aluminum flywheel with steel clutch facing
• 157-tooth steel ring gear (riveted)
• Clutch alignment dowel pins for 10.5-inch clutch

Key Features

• Riveted steel clutch facing permanently fastened to aluminum body - prevents ring gear separation under high loads
• 157-tooth ring gear for proper starter engagement on 5.0L HO applications
• 50oz external counterweight matches factory balance on 1981-1995 Ford 5.0L HO engines
• 19 lb total weight - reduces rotating mass versus stock cast iron flywheels
• Six-bolt crankshaft mounting pattern for direct replacement installation
• 10.4" metric clutch bolt pattern with alignment pins
• Made in the USA

Description

Cut rotating mass from your 5.0L drivetrain with this aluminum flywheel, purpose-built for 1981-1995 Ford 5.0L HO engines. Weighing just 19 lbs, it delivers noticeably quicker throttle response and faster RPM changes compared to stock cast iron units - ideal for road racing, autocross, and spirited street driving where nimble engine response matters more than low-RPM grunt.

The critical engineering detail is the riveted steel clutch facing. Unlike cheaper aluminum flywheels that rely on shrink-fit alone, this design permanently fastens the steel ring gear to the aluminum body using mechanical fasteners. This prevents the ring gear from walking or separating under hard launches and high-heat clutch engagement - a common failure mode when differential thermal expansion rates cause the steel ring gear to loosen on an aluminum body.

The 50oz external imbalance is factory-correct for Ford 5.0L HO engines from 1981-1995, ensuring smooth operation without vibration. The 157-tooth ring gear matches OEM specifications for proper starter motor engagement. Six-bolt crankshaft attachment follows Ford's original pattern, and the 10.4" metric clutch bolt pattern with alignment pins accommodates most performance clutch upgrades.

Important: Aluminum flywheels reduce stored rotational energy, which can make low-RPM driving feel less forgiving - they're easier to stall from a stop. This flywheel should not be paired with ceramic or bronze clutch discs, as the excessive heat generated can damage the aluminum body. It is recommended to warm the flywheel before installing on the crankshaft for optimal fit. Made in the USA.

Description

The importance of pressure plate bolts in racing or high-performance street applications cannot be emphasized nearly enough. These fasteners play a key role in both the performance and safety of a vehicle. Factory pressure plate bolts are notorious weak points that can stretch or fail under power, leading to clutch slippage, pressure plate distortion, or catastrophic failure. When you're building serious power, the last thing you want is substandard hardware compromising your drivetrain.

ARP engineered these High Performance Series bolts specifically for 1986-1995 Ford 302 and 351 Windsor applications. Each bolt is forged from premium-grade 8740 chromoly steel and heat-treated prior to thread rolling and machining, achieving a nominal tensile strength of 180,000 PSI. The application-specific design ensures optimum grip length for your Ford V8, eliminating the guesswork that comes with generic hardware.

The 8mm x 1.25 threading matches factory specs while delivering vastly superior strength. Each bolt features a hex head design with 10mm socket access for easy installation and removal. The black oxide finish provides corrosion resistance while maintaining a clean appearance under the hood. The large diameter, low profile design increases clamping force compared to stock bolts, reducing the risk of pressure plate flex under high-load conditions.

Fits all 1986-1995 Ford applications equipped with 302 or 351W engines, including Mustang 5.0L, F-150 trucks, Bronco, E-Series vans, and Crown Victoria. Kit includes six pressure plate bolts with washers for complete replacement of all factory fasteners.

Description

Factory plastic clutch hoses expand under pressure, robbing you of pedal feel and hydraulic efficiency. This stainless steel braided line eliminates that flex entirely, delivering a firmer pedal and more precise clutch engagement. The braided stainless construction contains pressure without expansion while remaining flexible enough for easy routing through tight engine bays.

This conversion line features different AN sizes at each end: a -4AN female straight fitting on one side and a -3AN female straight fitting on the other. That makes it ideal for bridging components with mismatched ports--common in hydraulic clutch conversions, transmission swaps, and custom plumbing applications where master cylinders and slave cylinders use different fitting sizes.

The Teflon inner lining ensures compatibility with DOT brake fluids and other hydraulic fluids while providing a slick interior surface that reduces friction. A clear plastic outer coating protects the stainless braid from road debris and corrosion while letting the quality construction show through. Every line is pressure tested before shipping to ensure leak-free performance in demanding applications.

Perfect for hydraulic clutch systems, racing applications, and high-heat environments where rubber hoses would degrade. Compatible with both internal and external slave cylinder setups. Made in the USA with premium materials throughout.

• 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.

Kit Includes

• 17-tooth speedometer driven gear, white plastic

Speedometer Driven Gear | Ford T5/T45/TKO/TKX/Magnum | 18-Tooth Yellow

Key Features

• 18-tooth driven gear for speedometer calibration on Ford-pattern transmissions
• 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
• 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.

What's Included

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

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.
