Installation Procedure


    Object Number: 190633  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.

    Important: The correct thread engagement is critical. The cross-threaded fittings can achieve proper tightness and still leak.

  1. Install the transaxle oil cooler fittings (28 and 29) to the transaxle.
  2. Tighten
    Tighten the transaxle oil cooler fittings to 38 N·m (28 lb ft).

  3. Install the transaxle oil cooler hoses to the transaxle oil cooler fittings. Refer to Automatic Transmission Oil Cooler Hose Replacement .
  4. Lower the vehicle.
  5. Notice: Do NOT overfill the transaxle. The overfilling of the transaxle causes foaming, loss of fluid, shift complaints, and possible damage to the transaxle.

  6. Adjust the fluid level. Refer to the following information.
  7. •  Transmission Fluid Check
    •  Fluid and Lubricant Recommendations in Maintenance and Lubrication
    •  Approximate Fluid Capacities in Maintenance and Lubrication
  8. Inspect for proper completion of the repairs.
  9. Inspect for fluid leaks.
