Transmission Mount Inspection
WARNING: This page is about a different variant/trim than selected.
- Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle (Base) , or Lifting and Jacking the Vehicle (ZL1) , or Lifting and Jacking the Vehicle (Convertible) .
- Raise the transmission in order to remove the weight from the transmission mount and create slight tension in the rubber.
- Observe the transmission mount while raising the transmission. Replace the transmission mount if the transmission mount exhibits any of the following conditions:
- 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.
- 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. Refer to Transmission Rear Mount Replacement (MH3, MJK, MM6 Transmission) , or Transmission Rear Mount Replacement (M13 Transmission) .
- Lower the vehicle.
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 suspected fluid loss, verify that the source of the fluid is the transmission mount, not the engine, transmission or accessories.
