BorgWarner Borg-Warner T-90

The Borg-Warner T-90 is a three-speed manual gearbox manufactured by Borg-Warner. It was used in most Willys and Kaiser-Jeep models from 1945 to 1971, as well as a number of International Harvester models. It is an improved version of the T-84 used in WWII Willys MB and Ford GPW military Jeeps. It was constructed with an iron case in both top-shift and side-shift variants. The gears are spur cut with only 2nd and 3rd gears synchronized.
