Transmission Mount Inspection
Notice: In order to avoid oil pan damage and possible engine failure, insert a block of wood that spans the width of the oil pan bottom between the oil pan and the jack support.
Important: Before replacing any transmission mount due to a suspected fluid loss, verify that the source of the fluid is the mount.
1. Raise the transmission/transaxle in order to relieve tension in the mount.
2. Observe the mount while raising the transmission/transaxle. Raising the transmission/transaxle removes the weight from the mount.
3. Replace the mount if it exhibits any of the following conditions:
^ The hard rubber surface is covered with heat check cracks.
^ The rubber is separated from the outer metal sleeve of the mount.
^ The rubber is split through the center of the transmission mount.
^ The mount is leaking fluid.
4. When replacing the transmission mounts or brackets, refer to the following procedures:
^ Transmission Front Mount Replacement
^ Transmission Rear Mount Replacement
^ Transmission Rear Mount Bracket Replacement
^ Transmission Mount Replacement - Left Side
