1. Install the J 21370-10 - pin gage into the low and reverse band servo pin bore.
2. Position the J 38737 - pin checking tool over the low and reverse band servo bore with the hex hub facing the parking pawl linkage.

Caution: Refer to Fastener Caution (Fastener Caution).

3. Fasten the J 38737 - pin checking tool to the case with 2 low and reverse band servo cover bolts (61). Tighten the bolts to 24 Nm (18 lb ft).

Note: The hex hub of the J 38737 - pin checking tool must be tightened in order to determine the correct low and reverse band servo piston pin length.

5. Tighten the hex hub of the J 38737 - pin checking tool. Tighten the hex hub of the J 38737 - pin checking tool to 34 Nm (25 lb ft).
6. Observe the lands on the J 21370-10 - pin gage in order to determine which land is even with the top edge of the J 38737 - pin checking tool. Note the letter (A, B or C) stamped on the J 21370-10 - pin gage.
7. Refer to the Low and Reverse Band Servo Piston Pin Specification table, in Transmission General Specifications (Transmission General Specifications) , in order to determine the correct pin length to use.
