Transmission Mount Inspection

WARNING: This page is about a different variant/trim than selected.
CAUTION:

To prevent transmission oil pan damage and possible transmission failure, insert a block of wood that completely covers the bottom of the transmission oil pan surface, between the transmission oil pan and the jack support. If the inserted block of wood does not completely cover the bottom of the transmission oil pan, this may result in damage to the transmission oil pan and possible transmission failure.

  1. Raise the transmission in order to remove the weight from the transmission mount and create slight tension in the rubber.
  2. Observe the transmission mount while raising the transmission. Replace the transmission mount if the transmission mount exhibits any of the following conditions:
      NOTE:

      Black paint on the rubber will crack with time, this does not constitute a failure.

    • The hard rubber surface is covered with heat check cracks.
    • The rubber is separated from the metal plate of the transmission mount.
    • The rubber is split through the center of the transmission mount.
  3. If there is movement between the metal plate of the transmission mount and its attaching points, lower the transmission on the transmission mount. Tighten the bolts or nuts attaching the transmission mount to the frame or transmission mount bracket.
