M1K2

Transmission Mount Kit Mack/Fuller

This is a transmission mount kit designed for Mack trucks with Fuller transmissions. It replaces the worn rubber bushings and hardware that support the rear of the transmission, reducing driveline vibration and preventing misalignment. The kit includes bushings, shackle bolts, lock nuts, and end washers—all the wear items needed for a complete rear mount service. Mechanics typically replace this when the transmission clunks under load or excess vibration is felt in the cab.
