T14 3-Speed Borg-Warner Manual Transmission Parts for Jeep CJ5
Bearings, Overhaul Kit and Shift Components for Your Transmission (1955–1975).
Why the T14 Transmission in the Jeep CJ5 Wears Out After Decades of Use.
The T14 transmission replaced the older T90 as the 3-speed gearbox in Jeep CJ5 and related models starting in the mid-1960s. Despite its compact, rugged design, typical wear appears after decades of use: the input shaft seal hardens and starts leaking, allowing gear oil to escape and reducing lubrication of the gear set. Bearings on the mainshaft and input shaft wear out, causing whining noises or noticeable play. The shifter boot tears or becomes brittle, letting dust and moisture into the transmission housing. Nuts loosen from vibration, and the poppet ball and shift knob wear from decades of shifting. Rebuilding your T14 or replacing individual wear parts noticeably restores smoothness and sealing.
- Bearings: The rear mainshaft bearing and input shaft / rear mainshaft bearing keep the gear train running smooth and quiet.
- Seal & Gasket Kit: The input shaft oil seal and the complete gasket and oil seal kit seal the transmission reliably.
- Overhaul Kit: The overhaul installation kit bundles bearings, seals and small parts for a complete rebuild.
- Mainshaft Hardware: The mainshaft nut secures the mainshaft.
- Shift Mechanism: The shifter boot, poppet ball and shift knob provide precise, comfortable shifting.
