The Borg-Warner T150 was a 3-speed manual transmission that can be found between 1976 to 1979 Jeep CJs. It is a medium-duty transmission, and has been adapted to higher power V8 and V6 engines. It is considered the second strongest of all Jeep three-speeds.
This transmission has three forward gears and one reverse. Only second and third gears are synchronized.
Unlike many Jeep transmissions previously, the T150 was bolted directly to the bellhousing and did not use an adapter plate. The front bolt pattern is common, and shares the same bolt pattern known as the “Ford Butterfly”. It features a 1.0625″ x 10 input shaft spline.
It was discontinued in 1979. It served it’s purpose of handling V8 power while small in size, but it was clear that it was time to move on to more modern 4 and 5 speed transmissions.

Ford – The T150 has a Ford style bolt pattern and can be used with classic Ford “butterfly” bellhousings. Ford V8s and other Ford engines will require the installation of a pilot bushing. The T150 input shaft will need to be ground down 5/8″ to prevent bottoming in the crank. Novak has a great information page about this modification.
