Borg Warner T90 3-Speed Jeep Transmission Parts

The T-90 is a 3 speed transmission with a casting number of T90 and a 1 1/8" 10 spline input shaft. Length of input shaft varies with application. Output is 1 3/8" 6 spline. The T-90s used in 1945 and some of 1946 where column shift. Later versions were floor shift.

This adapter is the factory adapter that was used with the T-86 and Dauntless Buick 225 V6 engine. Most likely, the transmission is a T-90 case that has been rebuilt with T-86 internals. Many parts interchange between the transmissions.

Usage: The T-90 was used in CJs from 1945 to 1971. It was also the standard 3 speed in the Willys Wagon, Willys Pickup, M38, M38A1, FC trucks, and Jeepster/Commandos during this time period. The only variation are the T-86 and T-14 used behind Jeeps equipped with the "Dauntless" Buick V6.
