The 4L60E transmission is a manual transmission that is used primarily in trucks, SUVs, and other vehicles. The 4L60E transmission is made up of four main components: the bell housing, the engine, the torque converter, and the fluid. The torque converter is used to change the torque made by the engine to the shaft of the transmission. The fluid connects the torque converter to the input shaft of the transmission. The fluid also protects the transmission. Need a 4L60E Transmission? Get a Used Transmission can help you find the right transmission for you.
