The All-Trac system had five main parts: the front differential, rear differential, center differential, the transmission, and the transfer case. The transmission, front differential, center differential and transfer case are all one large assembly and are connected to the transversely mounted engine. The transmission bell housing, front differential and center differential can be separated from the transfer case sub assembly. The transmission output shaft feeds power into the front/center differential assembly (the center differential is contained within the front differential). The center differential applied equal torque to both the front and rear wheels.
