Tools Required

J 37761 Universal 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.

23. Remove the 2 lower transmission-to-engine nuts (2) from the transmission.
24. 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, very slowly lower the transmission jack making sure there are no obstructions.
25. Inspect the transmission. For disassembly and inspection procedures, refer to Transmission/Transaxle/Transfer Case 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.
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 (1) 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.
