Inspection Of The Transmission

Check the transmission for oil leaks, as follows.

1. Check at the transmission output shaft for oil leaks. A small amount of oil and dirt accumulation is normal, as a small amount of oil is allowed past the seal to lubricate it. If the rear of the transmission is wet with oil, the rear seal may need replacing.
2. Check for oil leaks around the speedometer pickup.
3. Check the transmission case joints for oil leaks.
4. Check transmission oil line fittings for oil leaks.
5. Check the bottom of the flywheel housing for oil accumulation. Oil along the bottom seam or around the inspection cover of the flywheel housing may be an indication of a transmission input seal leak. Not replacing a leaking input oil seal will cause clutch slippage.
6. If leaks are found, take the vehicle to your Western Star dealer to have the problem corrected.
