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

Finding a bellhousing that properly connects your Ford FE big block to a Ford Toploader or short shaft TKO/TKX transmission while maintaining the dimensional accuracy your drivetrain demands is a challenge solved by the QuickTime RM-6057 steel bellhousing. QuickTime's unique spin-forming manufacturing process -- not rolled or stamped like inferior alternatives -- creates the most dimensionally stable bellhousing on the market, keeping your engine and transmission in perfect alignment through the entire RPM range and eliminating the accelerated drivetrain wear caused by bellhousing flex.

Built from high-grade steel that work-hardens to over 80,000 PSI during the spin-forming process, this bellhousing delivers more than twice the strength of other steel bellhousings while remaining lightweight at just 22 pounds. The result is maximum protection without adding unnecessary weight to your build. Multiple transmission bore sizes (4.685", 4.850", 4.910", and 5.120") ensure precise alignment with your specific transmission, reducing drivetrain wear and maximizing power transfer to the wheels.

This bellhousing connects Ford FE engines including 332, 352, 360, 390, 406, 410, 427, and 428 cubic inch variants to early Ford Toploader, Borg Warner T10, and TKO 500/600 short shaft transmissions. With a 6.425-inch depth, it clears 184-tooth flywheels and 12-inch clutches while maintaining compact overall dimensions for tight engine bay installations. Universal shifter fork brackets are included for both diaphragm and cable-operated clutch linkage, giving you flexibility in your clutch actuation setup.

QuickTime, founded by former dirt track racer Ross McCombs, developed this bellhousing technology from the demands of racing where inferior bellhousings simply couldn't survive. Note that this bellhousing is not SFI certified, which is required by many sanctioning bodies for cars running 11.49 or faster in the quarter mile -- for SFI-rated applications, see the RM-6057SFI. This is a universal-fit bellhousing and is not vehicle-specific, making it ideal for custom builds, engine swaps, and restoration projects.

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.

What's Included

• Grade 8 steel transmission-to-bellhousing bolts (sized for steel bellhousing applications)

Description

Pressure plate bolts are among the most critical safety components in any drivetrain. These six fasteners are all that stands between a properly functioning clutch and a catastrophic failure that can destroy transmissions, scatter debris through the bellhousing, or worse. This isn't the place to grab whatever's sitting in the hardware drawer.

This six-bolt kit delivers the 5/16"-18 x 3/4" specification needed for the majority of domestic muscle cars and classic performance applications. The 5/16"-18 thread pitch provides the strength-to-weight balance that made this specification an OEM standard across Ford, GM, and Mopar platforms. The 3/4" under-head length accommodates most standard pressure plate thicknesses without bottoming out in flywheel threads or leaving inadequate engagement.

Unlike generic hardware-store fasteners, these bolts are designed specifically for clutch applications where vibration resistance, proper thread engagement, and precise clamping loads are essential. Proper pressure plate hardware prevents the loosening and shearing that leads to clutch separation under high-RPM loads. Whether you're rebuilding a numbers-matching classic or assembling a street/strip performer, using the correct pressure plate bolts isn't optional.

Compatible with most domestic clutch applications using 5/16" pressure plate bolts. Verify thread specification and length requirements for your specific application before installation.

Description

Every time you stab the throttle, your pressure plate bolts absorb the rotational forces trying to tear your clutch apart. Factory hardware is engineered to a price point - not a performance standard. ARP's High Performance Series pressure plate bolts are forged from premium 8740 chromoly steel and heat-treated to 180,000 PSI tensile strength, delivering a substantial margin of safety over standard Grade 8 fasteners that simply can't match this level of clamping force under stress.

These aren't generic bolts cut to length. Each fastener features a precisely engineered 0.780-inch underhead length optimized specifically for Ford 289-460 V8 applications (1985 and earlier). The large-diameter, low-profile hex head design provides increased shank strength and improved flywheel register engagement compared to OEM hardware. The black oxide finish not only resists corrosion in the harsh bellhousing environment but also looks right on a performance build.

Whether you're building a weekend warrior that sees occasional strip duty or a dedicated road course car that lives at high RPM, these bolts eliminate a critical weak point in your drivetrain. The included hardened washers distribute clamping load evenly across the pressure plate mounting surface, preventing galling and ensuring consistent torque values. For best results, ARP recommends using their Ultra-Torque assembly lubricant to achieve accurate, repeatable torque readings.

Description

Swapping a T5, TKO, TKX, or AOD into your '65-'66 Mustang means your original speedometer cable won't reach or connect properly to the new transmission. This 59" speedometer cable solves that problem, routing from your factory mechanical speedometer head to the speedometer drive on your modern transmission while maintaining accurate speed readings on your original dash.

The cable features the correct 5/8" barrel-style fitting that interfaces directly with the speedometer head used in 1965-1966 Mustangs. At 59" long, it provides proper reach for the routing requirements created by T5, TKO, TKX, and AOD transmission placements in these chassis. The cable also works with original 3-speed manual and automatic transmission configurations, making it a versatile solution whether you're completing a five-speed conversion or simply replacing a worn cable on an automatic-equipped car.

For builders who want to keep the original instrument cluster looking stock while running a modern drivetrain, this mechanical speedometer cable eliminates the need for electronic speedometer conversions or aftermarket gauges. Pair it with the correct driven gear for your tire size and rear axle ratio to dial in accurate speed readings.

What's Included

• 59" speedometer cable with 5/8" barrel connector
• Manufacturer's warranty

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

• 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.
