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 in Engine Mechanical.
