Assembly

Low/reverse piston

1. Install new low/reverse outer piston O-ring seal.





2. Install new low/reverse drum O-ring seal.





3. Lubricate the O-ring seal with clean transmission fluid. Align the alignment tab on the piston with the groove in the center support and install the low/reverse piston.

7. NOTE: All low/reverse clutch plates, friction and steel are of a wave-type design.

Install the D-Clutch Measurement Gauge into the case.





8. With the D-Clutch Measurement Gauge positioned in the case, use the Depth Micrometer to measure the case stop depth.









9. Measure the clutch pack height.









10. Using the Depth Micrometer, measure the piston to center support shoulder height.









11. Calculate the end clearance.





Compare the end clearance to the specification. If the end clearance is out of specification, select the next thinner or thicker plate as required and repeat Steps 10, 11 and 12.
