How to replace the Motor and Transmission Mount on an Allison automatic transmission on GMC Sierra 3500 Classic?

Begin transmission mount replacement by lifting and supporting your vehicle and installing a transmission jack to stabilize the transmission. You must first eliminate the transmission mount from the transmission support retaining nut before raising the transmission above its original position to remove tension on the mount. Start by removing the transmission mount from the transmission or transfer case adapter mounting bolts until you can raise the transmission properly for removal of the mount. Install the new transmission mount into its position inside the vehicle before tightening the transmission and transfer case adapter mounting bolts to 50 n.m (37 lb ft). Lower the transmission while securing the mount to the transmission support retaining nut or nuts by torquing them to 40 n.m (30 lb ft). Finish by removing the transmission jack and letting the vehicle lower to the ground.
