from the diesel engine is sent from the flywheel to the torque converter through an arrangement of the flex drive plate.A pilot bore in the flywheel provides alignment for the front end of the torque converter during installation.The torque converter features a free wheel clutch that allows the converter stator to free wheel during high speed and during low load conditions. A stator that is free wheeling changes the converter into a fluid coupling for better efficiency at the high speed end.The transmission has the following features: manual four speeds, direct drive helical gear, constant mesh, synchronized arrangement, and coupled with hydraulically shifted forward and reverse shuttle clutches.
