How to Inspect the Motor and Transmission Mount on Cadillac STS?

Before checking the transmission mount start by placing a wooden block between the Oil Pan bottom and the jack support that matches the Oil Pan width to safeguard the Oil Pan and engine. You should now lift the transmission/transaxle to remove its weight from the mount which produces some elastic tension in the rubber material. While doing this, observe the transmission/transaxle mount for any of the following conditions that necessitate replacement: heat check cracks appear on the hard rubber surface or the rubber detaches from its metal plate or it splits completely through its center. Lower the transmission/transaxle while tightening the bolts or nuts which attach the transmission/transaxle mount to the frame or transmission/transaxle mount bracket if you observe movement between the metal plate and its attachment points.
