Borg-Warner T90 Transmission Parts for CJ
The Borg-Warner T90 transmission was one of the most common transmissions found in 1946 to 1971 Jeep CJ's. Because of its long production span, it is nearly legendary. It is a good transmission when well maintained and has often been adapted to V8, V6 and I4 power.
The T90 was the improved progeny of the T84, of military MB & GPW fame. The T90 was the standard three-speed as found in CJ Universals, Utility Trucks & Wagons, J Series and Forward Control Trucks.
