GM Genuine Parts Automatic Transmission Input Shafts are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These shafts transfer the power of the engine crankshaft to the transmission, which is then transferred to the wheels through the output shaft, causing your vehicle to move. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).
