Tools Required

J 37761 Clutch Alignment Arbor

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

7. Remove the VSS retaining bolt (1), then disconnect the ground strap from the transmission.



8. Loosen the wire harness retainer on the right side of the transmission, then position harness out of the way.



9. Remove the engine exhaust support from the transmission.
10. Place a drain pan or a suitable container under the transmission tail housing.
11. Place index marks on the propeller shaft pinion flange yoke and the differential pinion flange to ensure correct installation.
12. Remove the following items from the vehicle:

•	The 4 bolts

•	The 4 nuts

•	The rear propeller shaft

13. Remove the 2 bolts from the flywheel inspection cover, then remove the cover from the transmission.



14. Remove the 2 hydraulic slave cylinder retaining bolts from the transmission, then position the slave cylinder aside.



15. Remove the 2 bolts from the rear transmission mount.
16. Support the transmission with a suitable hydraulic jack.
17. Support the front of the engine assembly with a suitable jack and a block of wood.
18. Remove the transmission crossmember from the vehicle
19. Remove the 2 right side transmission to engine bolts.
20. Position the transmission ground strap aside.
21. Remove the right upper transmission to engine bolt.
22. Remove the upper left transmission retaining nut.
23. Remove the 2 lower transmission retaining nuts.
24. Remove the drain pan from under the vehicle.

Important: Slightly lower the transmission to gain access to the backup lamp switch connector and breather tube.

25. Disconnect the backup light switch connector from the switch.

Disconnect the breather hose from the transmission.

Remove the transmission from the vehicle by carefully moving the transmission away from the engine toward the rear of the vehicle until the input shaft is clear of the clutch pressure plate cover. Then slowly lower the transmission jack making sure there are no obstructions.

26. Inspect the transmission. For disassembly and inspection procedures, refer to Transmission Unit Repair Manual.

1. Inspect the clutch alignment by inserting the J 37761 through the clutch disc and into the crankshaft pilot bearing. If the J 37761 does not fit through the clutch disc and into the pilot bearing assembly smoothly, the clutch disc may be misaligned. For clutch disassembly and inspection procedures, refer to Clutch Assembly Replacement in Clutch and align if necessary.

Important: Raise the transmission to a position where the backup light switch connector can be connected and the breather tube can be installed before installing the transmission to the engine assembly.

2. Install the transmission to the engine by raising the transmission into position and moving the transmission toward the engine while simultaneously inserting the transmission input shaft through the pressure plate cover and the clutch disc into the crankshaft pilot bearing.

Notice: 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.
