Transmission Mount: Testing and Inspection

Transmission Mount Inspection

Caution:
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 the transmission/transaxle in order to remove the weight from the transmission/transaxle mount and create slight tension in the rubber.

2. 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:

Note:
Black paint on the rubber will crack with time, this does no constitute a failure.

* 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.

3. 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.
