Transmission Parts for Willys CJ3B
Bearings, Gaskets & Hardware for T90 and T98 Transmissions (1953–1964).
Why the T90 and T98 Transmissions in the Willys CJ3B Wear Out After Decades.
Depending on year and configuration, the Willys CJ3B left the factory with either the simpler 3-speed T90 or the more rugged 4-speed T98 transmission – both Borg-Warner designs share many of the same wear points. Input and output shaft bearings lose their precision through mileage and declining oil quality, showing up as noise and play. Seals and gasket kits harden over the decades and start leaking gear oil. Lock nuts and spacers on the mainshaft loosen from vibration, while shift rail balls and shift knobs in the shifting mechanism wear out, leading to imprecise gear changes. Anyone restoring or driving a historic Willys CJ3B should keep an eye on the wear parts specific to their transmission type.
- Bearings: The input shaft bearing T90/T150 and the output shaft bearing T86/T90/T150 for the T90 transmission, plus the input shaft bearing T15/T18/T150 and the rear mainshaft bearing T18/T98/T176/T177 for the T98 transmission.
- Seals & Gaskets: The gasket kit for the T90 transmission, the gasket kit including seals for the T98 transmission, the individual seal, and the transfer case housing gasket keep the transmission reliably sealed.
- Complete Rebuild Kit: The repair kit for the T90 transmission with bearings, seals, gaskets, needles, snap rings and washers covers a full rebuild.
- Shift Mechanism: The shift rail ball...

- Shift Mechanism: The shift rail ball and the shift knob ensure clean, comfortable shifting.
- Mainshaft Hardware: The washer, the lock nut, and the spacer secure the mainshaft reliably.
