Removal Procedure


    Object Number: 242867  Size: SH
  1. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
  2. Remove 6 bolts and the left splash shield (1) from the vehicle.
  3. Place a drain pan or a suitable container under the transaxle fluid pan.

  4. Object Number: 242982  Size: SH
  5. Remove the transaxle drain plug (2) from the transaxle fluid pan (1) and drain the transaxle fluid.
  6. Notice: When removing the transaxle fluid pan, use caution in order not to damage the transaxle case-to-fluid pan mating surfaces. If the fluid pan is frozen to the transaxle case, use a rubber mallet and a wood block to lightly tap the fluid pan free. Do not attempt to pry the fluid pan away from the case with metal tools; damage to the case or fluid pan flange could result.

  7. Remove 18 bolts, the transaxle fluid pan, and the fluid pan gasket from the transaxle.

  9. Remove 3 bolts, the fluid filter screen (1), and the gasket from the valve body.
  10. Important: A small amount of clutch material in the bottom of the transaxle fluid pan is a normal condition and is consistent with normal transaxle wear. The bottom of the fluid pan is equipped with a magnet that will collect minute metal filings. However, if large amounts of clutch material, metal shavings or other foreign matter are present, disassembly and inspection of the transaxle is indicated.

  11. Inspect the bottom of the fluid pan for any large pieces of metal or other foreign matter.
  12. Clean the fluid filter screen with solvent and dry thoroughly. If the screen mesh is damaged, replace the filter screen.

Installation Procedure


    Object Number: 242987  Size: SH

    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  1. Install the fluid filter screen gasket (1) and the fluid filter screen (2) to the valve body assembly. Secure the screen with 3 bolts.
