1979-93 Mustang Parts
Get everything you need to fix or replace your 1979-1993 Mustang manual transmission with our selection of T5, TKX, and T56 transmissions & components at LMR!
Whether you’re fixing a worn transmission or upgrading to something stronger, fitment comes down to the transmission you’re running and the year range of your Fox Body. The Tremec heavy-duty “World Class” T5 is the stock-style 5-speed choice. For more overdrive, the Tremec TKX 5-speed comes in 10-spline and 26-spline versions, with .68, .72, and .81 overdrive ratios. For a 6-speed, the Tremec T56 Magnum is available with a 2.97 or 2.66 first gear. We also offer swap kits for 1982-1993 and 1987-1993 Fox Bodies, including versions without a driveline. The TKX and T56 transmissions are listed through 2004, so they also fit later Mustangs. When you move to an aftermarket transmission, you may need a matching bellhousing, so it’s worth confirming before you order.
Transmission parts depend on which transmission you have. T5 owners have rebuild kits, input shaft bearings, tail shaft seals, and an upgraded steel bearing retainer to replace the stock aluminum one that can wear and cause clutch engagement problems. TKX owners have an input shaft seal and install kit for the cast bellhousing, and T56 owners have shifter bushings, pigtail kits, and a reverse lockout solenoid delete. Neutral sensing switches, reverse light switches, speed sensors, and harnesses finish the job, and fluid kits from Motorcraft, Royal Purple, and Tremec keep it all running smoothly.

Our Fox Body specialists help customers match transmissions, swap kits, and parts to their exact year, engine, and goals every day. If you’re deciding between a T5, TKX, or T56, or you’re not sure whether your car needs a different bellhousing or driveline parts, reach out and we’ll help you confirm before you order.
