Inspection Procedure

WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
    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.
    NOTE: 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:
