  1. Install the eight check balls in the proper location into the case fluid passages.
  2. Install the gasket.
  3. Install the complete valve body assembly onto the case.
  4. Be sure to attach the manual shaft to the detent lever and the pin assembly.
  5. Install the pressure switch manifold (PSM) onto the valve body assembly.
  6. Install the spring and roller assembly into place.
  7. Install the three wiring clips and the fluid indicator stop.
  8. Install the twenty-one bolts using a 10-mm socket.
  9. Tighten
    Tighten the bolts to 11 N·m(96 lb in).

    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.
