The Borg-Warner T150 transmission was the three-speed transmission found in 1976 to 1979 Jeeps. It is a good transmission when well maintained and has often been adapted to V8 and V6 power.
Rated at medium-duty, the T150 is stronger than its compact size may suggest. Though it only holds a candle to the truck style four-speeds' strengths and capabilities, the T150 is frequently retained in CJ Jeeps when married to mild GM V6 and V8 power. It is regarded as the second strongest of all the Jeep three-speeds, second to the Jeep T15.
