2001 Oldsmobile Alero V6-3.4L VIN E

Automatic Transmission/Transaxle Fluid - A/T Service and Repair


The fluid level screw is intended to be used for diagnosing a transaxle fluid leak or resetting the transaxle fluid level after service that involves a loss of fluid.


The fluid level should be checked when the transaxle is near Room temperature or at 40°C (104°F) . CAUTION: Removal of the fluid level screw when the transaxle fluid is hot may cause injury. Use care to avoid contact of transaxle fluid to exhaust pipe.

The engine must be running when the transaxle fluid level screw is removed, or excessive fluid loss will occur. Since the actual fluid level is unknown, stand clear when removing the fluid level screw. Have a container ready to capture any lost fluid.

WARNING: Do not turn the engine off with the fluid level screw removed as you can be injured by hot transaxle fluid being expelled out of the fluid check hole.

1. Let vehicle idle for three to five minutes with accessories off.

2. Apply brake

3. Move shift lever through all gear ranges, pausing three seconds in each range.  Download File PDF
