How to replace the Motor and Transmission Mount for the 4.2L engine on Buick Rainier?

The first step in replacing the 4.2l transmission mount involves lifting the vehicle and positioning a transmission jack under the component. Unbolting the nuts that connect the transmission mount to the transmission support will allow you to extract the transmission support out of the vehicle. The process starts with removing transmission mount bolts (1, 2) and the bolt which joins the transmission mount to the Exhaust Hanger before separating the transmission mount from the Exhaust Hanger for removal. Attach the transmission mount to the Exhaust Hanger bracket before securing it with a bolt to 30 n.m (22 lb ft). Use bolts (1, 2) to fasten the transmission mount to the transmission components at 65 n.m (48 lb ft). Replace the transmission support while you eliminate the transmission jack from service. The last step involves tightening nuts on the transmission mount to the transmission support until torque reaches 46 n.m (35 lb ft) before lowering the vehicle.
