  4. Place a straight edge on top of the second clutch sprag outer race thrust washer.
  5. Measure the distance (b) from the bottom of the straight edge and the fluid pump assembly. Installed height should be 51.09-51.71 mm (2.011-2.036 in).
  6. If the installed height is greater than specifications, the second coast clutch hub did not clear all the second clutch fiber plates. Index again the clutch hub and plates until within specifications.

  12. Rotate the transmission assembly so that the fluid pump assembly is facing up.
    13. CAUTION: 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.
  13. Tighten the fluid pump to case bolts in the correct sequence. Tighten the fluid pump to case bolts to 25 N.m (18 lb ft).
