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. Use a jack or a utility stand to raise the transmission/transaxle in order to remove the weight from the transmission/transaxle mount and create slight tension in the mount.
  2. Inspect the transmission/transaxle mount. Replace the transmission/transaxle mount if the transmission/transaxle mount exhibits any of the following conditions:
  3. • The rubber surface is covered with cracks.
    • The rubber is separated from the metal plate of the mount.
    • The rubber is split through the center.
  4. If there is movement between the metal plate of the transmission/transaxle mount and the transmission, tighten the transmission mount fasteners to the correct tightening specification.

For information on the engine mount, refer to Engine Mount Inspection for the 3.5L engine and Engine Mount Inspection for the 3.6L engine.
