H/C 5618988

Defect Code: 051

Out of warranty:
Any repair performed after warranty expiration may be eligible for goodwill consideration by the District Service Manager or your Zone Office. You must request consideration, and get a decision, before starting work.

*DIAGNOSIS

Clean the area with a shop towel where the engine block and transmission meet. Start the engine, and look for oil leakage from the area with the aid of a powdered leak detector.

^ If you see any signs of leakage, go to REPAIR PROCEDURE.

^ If you see no signs of leakage, then what looked like leakage may have been excess residue from a previous repair on another part. Continue with normal troubleshooting.

REPAIR PROCEDURE

1. Remove the transmission. Refer to section 13 or 14 of the appropriate service manual.

2. Remove and discard the rear main oil seal (crankshaft oil seal).

3. Install the new oil seal. Refer to page 7-29 of the '96-00 service manual or page 7-27 of the '01 service manual.

4. Reinstall the transmission.

5. Reinstall the drain plug with a new sealing washer.

6. Refill the transmission with the appropriate fluid.

7. 2001 models only Do the idle learn procedure:

^ Make sure all electrical items (A/C, audio unit, defogger, lights, etc.) are turned off, then start the engine.

^ Let the engine warm up to its normal operating temperature (the cooling fan cycles twice).

^ Let the engine idle (throttle fully closed with all electrical items turned off) for 10 minutes.

8. 2001 2-door EX and LX models only Drive the vehicle above 40 mph for 5 to 10 minutes with the cruise control on. (This lets the cruise control actuator learn how much slack there is in the throttle cable.)*
