T150 Manual 3-Speed Tremec Transmission Parts for Jeep CJ5
Shafts, Gears, Bearings & Seals for Reliable Shifting (1976–1979).
Why the T150 Transmission in the Jeep CJ5 Wears Out After Decades.
Starting in 1976, the Borg-Warner T150 manual transmission replaced the older T90 in the Jeep CJ5, reliably transferring power from the 2.5- to 5.0-liter engines to the drivetrain as a rugged 3-speed gearbox. After decades of service, though, typical wear shows up: the mainshaft and countershaft develop play in their bearing seats from sustained load, while 2nd and 3rd gear synchronizer rings wear thin from friction and cause notchy shifting. Input and output shaft oil seals harden and start leaking, letting gear oil escape. The clutch lever wears at its contact point, snap rings and thrust washers lose their fit from vibration, and under heavy use the housing bell can develop cracks. Anyone running a T150 off-road or on larger tires should check these wear parts regularly to avoid costly follow-on damage to shafts and gears.
- Shafts & Gears: The main shaft and the 1st gear form the mechanical heart of the transmission.
- Synchronizers & Shift Parts: The 2nd and 3rd gear synchronizer and the 2nd and 3rd gear shift fork keep shifting precise.
- Bearings & Seals: The transmission bearing kit and the gasket and oil seal kit prevent oil leaks and play.
- Repair Kits & Small Parts: The master overhaul kit and the small parts master repair kit cover a complete rebuild.
- Clutch & Switch: The clutch lever and the reverse light switch round out the range.
- Housing & Transfer Case Connection: The housing bell and the transmission mount insulator for the Dana 300 transfer case provide a stable connection to the drivetrain.
Proven American Brand Quality for the T150 Transmission.
Shafts, bearings, gasket kits, and the housing bell come from Crown Automotive – American engineering that has proven itself in the Jeep parts market for decades. The 2nd and 3rd gear synchronizer ring is supplied by Omix, also American-made, while the reverse light switch comes from Standard Ignition. All three brands deliver precision-fit quality that matches the original.
