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.

1. Raise and support the vehicle.
2. Place a jack stand under the transmission/transaxle.
3. Place a block of wood between the jack stand and the transaxle in order to protect the transmission/transaxle pan.

4. Important Before replacing any transmission/transaxle mount due to suspected fluid loss, verify that the source of the fluid is the transmission/transaxle mount, not the engine, transmission/transaxle or accessories.

Raise the transmission/transaxle in order to remove the weight from the transmission/transaxle mount and create slight tension in the rubber.
5. Observe the transmission/transaxle mount while raising the transmission/transaxle. Replace the transmission/transaxle mount if the transmission/transaxle mount exhibits any of the following conditions:
^ The hard rubber surface is covered with heat check cracks.
^ The rubber is separated from the metal plate of the transmission/transaxle mount.
^ The rubber is split through the center of the transmission/transaxle mount.
6. If there is movement between the metal plate of the transmission/transaxle mount and its attaching points, lower the transmission/transaxle on the transmission/transaxle mount. Tighten the bolts or nuts attaching the transmission/transaxle mount to the frame or transmission/transaxle mount bracket.
7. Remove the Jack stand and block of wood from under the vehicle.
8. Lower the vehicle.
