Service Information: Disassembly
NOTE:
If the transmission is being reconditioned (clutch/seal replacement) or replaced, it is necessary to perform the Quick Learn Procedure using the scan tool (Refer to ELECTRICAL/ELECTRONIC CONTROL MODULES/TRANSMISSION CONTROL MODULE - STANDARD PROCEDURE)
.
| 1 - MANUAL SHAFT LEVER |
- Drain fluid from transmission.
- Clean exterior of transmission with suitable solvent or pressure washer.

1 - OUTPUT SPEED SENSOR 2 - LINE PRESSURE SENSOR 3 - INPUT SPEED SENSOR - Remove the input (3), output (1), and line pressure sensors (2) from the transmission case. See Fig 2
- Inspect the ends of the sensors for debris, which may indicate the nature of the transmission failure.
1 - TOOL 8257 - Install Support Stand 8257 (1) onto the transmission case. See Fig 3
1 - TOOL 8266 2 - TOOL C-3339 - Using Adapter 8266-1 from End-Play Tool Set 8266 (1) and Dial Indicator C-3339 (2), measure and record the input shaft end-play. See Fig 4NOTE: When measuring the input shaft end-play, two "stops" will be felt. When the input shaft is pushed inward and the dial indicator zeroed, the first "stop" felt when the input shaft is pulled outward is the movement of the input shaft in the input clutch housing hub. This value should not be included in the end-play measured value and therefore must be recorded and subtracted from the dial indicator reading.
1 - TOOL 8261 2 - TOOL 8266 3 - TOOL C-3339 - Remove the bolts holding the transmission extension/adapter housing to the transmission case.
- Remove the extension/adapter housing from the transmission case.
- Using Alignment Plate 8261 (1), Adapter 8266-17 from End-Play Tool Set 8266 (2) and Dial Indicator C-3339 (3), measure and record the output shaft end-play. See Fig 5

1 - OIL PUMP TO CASE BOLT (6) 2 - OIL PUMP CAUTION: If the input shaft is not held during oil pump removal, the input clutch assembly will attempt to move forward with the oil pump and the numbers 2, 3, or 4 bearings inside the input clutch assembly may become dislodged. - Remove the bolts (1) holding the oil pump into the transmission case. See Fig 9
- Remove the oil pump (2). Hold inward on the input shaft to prevent pulling the input clutch assembly with the oil pump. See Fig 9
