T176 & T177 Manual 4-Speed Tremec Transmission Parts for Jeep CJ5
Shafts, Gears, Bearings & Seals for Reliable Shifting (1980–1986).
Why the T176 and T177 Transmissions in the Jeep CJ5 Wear Out After Decades.
Starting in 1980, the Borg-Warner T176 (4-speed, standard) and T177 (4-speed, overdrive) transmissions replaced the older T150 in the Jeep CJ5, reliably transferring power from the 2.5- to 5.9-liter engines of that era to the drivetrain. After decades of service, though, typical wear shows up: 3rd and 4th gear synchronizer rings wear thin from friction and cause notchy shifting, while input and output shaft bearings develop play from sustained load. Oil seals harden and start leaking, letting gear oil escape. Shift forks and shift lever bushings wear mechanically, snap rings and thrust washers lose their fit from vibration, and under heavy use the housing bell can develop cracks. Anyone running a T176/T177 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 19-tooth input shaft form the mechanical heart of the transmission.
- Synchronizers & Shift Forks: The 3rd and 4th gear synchronizer assembly and the 1st and 2nd gear shift fork keep shifting precise.
- Bearings & Seals: The transmission bearing kit and the gasket and seal kit prevent oil leaks and play.
- Repair Kits & Small Parts: The transmission overhaul kit and the small parts master repair kit cover a complete rebuild.
- Shift Lever & Knob: The shift lever and the shift lever repair kit give you a precise, tight shift feel.
- Housing, Clutch & Switch: The housing bell and the complete clutch master kit round out the range.
