- Gently lift the plunger of the dial indicator off the transmission case step, slide the dial indicator over and drop the plunger onto the No. 2 sun gear thrust bearing. Record this distance as measurement A.
- With measurement A recorded, calculate the selective shim thickness and find the part number.
- Zero
- Measurement A
- Subtract 8.55 mm (0.336 in) from measurement A to get the clearance for the rear shim. Compare the clearance of the rear shim to the Rear Selective Shim Part Number Chart in Specifications to get the correct selective shim dimension and part number. The target clearance with the correct rear shim installed should be between 0.8-1.1 mm (0.031-0.043 in).
NOTE: The distance on the center support from the transmission case surface to the No. 2 sun gear thrust bearing surface equals 8.55 mm (0.336 in). 8.55 mm (0.336 in) is subtracted from measurement A to compensate for the offset of the center support. - Install the rear selective shim on top of the thrust bearing.

- Position the End Play Gauge on the pump with it centered to the center of the stator support. Using a suitable depth gauge, measure the distance from the top of the End Play Gauge to the front shim surface in 2 places, 180 degrees apart. Average the 2 measurements and record as measurement A.
- Using a suitable depth gauge, measure the distance from the top of the End Play Gauge to the deck surface in 2 places, 180 degrees apart. Average the 2 measurements and record as measurement B.
- Subtract measurement A from measurement B and record as measurement C.
- Position the End Play Gauge on the transmission case pump deck surface. Using a suitable depth gauge, measure the distance from the top of the End Play Gauge to the selective shim surface on the No. 1 sun gear. Subtract the height of the End Play Gauge 12.7 mm (0.5 in) from the measurement and record as measurement D. Remove the End Play Gauge.
- Subtract measurement C from measurement D and record that distance as the front selective shim thickness. Compare the thickness of the center support shim to the Front Selective Shim Part Number Chart in Specifications to get the correct front selective shim part number. The target clearance with the correct front shim installed should be between 0.15-0.45 mm (0.006-0.018 in).
- Install the selective shim on top of the No. 1 sun gear. Make sure the selective shim is positioned correctly in the No. 1 sun gear groove.
