How to replace the Motor and Transmission Mount for the 4.2L engine on 2004 Buick Rainier?

You need to raise the vehicle so you can support the transmission with a proper jack before changing the transmission mount for a 4.2l engine. Start by removing the nuts holding the transmission mount to the transmission support before removing the support from beneath the vehicle. Unbolt transmission mount bolts (1, 2) and Exhaust Hanger bolt until the mount detaches from the hanger before you remove it entirely from the vehicle. Secure the transmission mount to the Exhaust Hanger bracket by using a bolt and torque it to 30 nm (22 ft. Lbs.). Use bolts (1, 2) to secure the transmission mount before tightening them to 65 nm (48 ft. Lbs.). After reattaching the transmission support you should remove the transmission jack and secure the transmission mount to its fitting by torquing nuts to 46 nm (35 ft. Lbs.). Lower the vehicle afterwards.
