Tools Required

1. Install the shift shaft bushing. Use the J 39437 .



2. Install the mainshaft bearing race. Use the J 39546 and the J 8092 .



3. Install the mainshaft bearing race retainer ring.



4. Install the rear seal and boot (Locate the drain hole in the rear seal and boot down). Use the J 39440 .



5. Install the following parts:

5.1.	The O-ring seal to the vehicle speed sensor

5.2.	The vehicle speed sensor and the clamp

5.3.	The vehicle speed sensor bolt

Tighten
The bolt to 10 N·m (89 Ib in).

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.

Caution: The reverse lockout assembly is under spring pressure. Exercise caution when removing the retainer ring, as bodily injury may result.

6. Assemble the reverse lockout assembly in the following sequence:

6.1.	Refer to Extension Housing (1 of 2)
