Transmission Fluid Filling Procedure
Use the following procedure in order to refill the transaxle, as necessary:
- Place the vehicle on a level surface.
- Remove the fluid level indicator.
- Add approximately 3.1 liters (3.25 qts) of AC Delco T-IV automatic transmission fluid GM P/N 88900925 into the fluid filler tube.
- Install the fluid level indicator into the fluid filler tube.
- Apply the parking brake and block the vehicle wheels.
- With the selector lever in the P position, start the engine. Do not race the engine.
- Run the engine at idle and move the selector lever through each range and return it to the P position.
- With the engine running at idle, remove the fluid level indicator from the filler tube and wipe the indicator off.
- Reinsert the fluid level indicator into the filler tube making sure it is seated in its original position.
- Remove the indicator and inspect the fluid level.
Important: The engine and the transmission must be at operating temperature for the transmission to register correctly at the HOT level range.
The level should be between the FULL HOT and the LOW HOT marks.
If the level is below the LOW HOT mark, add fluid in order to bring the level to the FULL HOT mark. Bringing the fluid level from the LOW HOT mark to the FULL HOT mark requires 0.3 liters (0.3 qts) of fluid. Use AC Delco T-IV automatic transmission fluid GM P/N 88900925.
