Transmission Fluid Check: Procedure
NOTE:
Routine inspection of the transaxle fluid is not required. Transaxle fluid inspection is only required if there is a symptom indicating a concern with the fluid.
- Park the vehicle on a flat level surface.
- Operate the vehicle in order for the transmission fluid temperature to reach the normal operating range.
Specification
Transaxle normal temperature: 60-70°C (140-158°F)
- With the engine at idle, manual shift through all transaxle ranges and return to the PARK position. Leave the engine idling.
- Clean any dirt or debris away from the area of the transaxle fluid level indicator.
- Remove the transaxle fluid level indicator bolt (1) from the transaxle.
- Remove the transaxle fluid level indicator (2).
- Wipe away any transaxle fluid from the indicator.
- Insert the indicator into the transaxle until fully seated.
NOTE: Inspecting transaxle fluid level when not at normal temperature can give an incorrect measurement. The transaxle fluid expands when warm.
- Remove the indicator and inspect the level and the condition of the oil on the indicator:
- Transmission fluid level at normal operating temperature (1)
- Transmission fluid level if cold (2)
- If the fluid level is incorrect inspect for the following conditions:
- Fluid below level, inspect for a leak. Refer to FLUID LEAK DIAGNOSIS or AUTOMATIC TRANSMISSION FLUID LEAKS .
- Fluid above level, inspect for contamination of the fluid.NOTE: The transaxle uses T-IV fluid, GM P/N 88900925 (Canadian P/N 22689186). The fluid is normally red in color. The oil may darken in color with more miles on a vehicle.
- Inspect the condition of the fluid for the following conditions:
- Excessively dirty with particles in the fluid
- If there are no driveability concerns, replace the fluid. Refer to TRANSAXLE FLUID REPLACEMENT .
- If driveability concerns are present disassemble and inspect for a cause.
- Burnt smell
- Inspect for the correct fluid. Refer to FLUID CAPACITY SPECIFICATIONS .
- Inspect for conditions that may of cause overheating of the transmission fluid. Refer to TRANSMISSION OVERHEATS .
- If there are no driveability concerns, replace the fluid. Refer to TRANSAXLE FLUID REPLACEMENT .
- If driveability concerns are present disassemble and inspect for cause.
- Inspect the transmission oil cooler system for functioning properly. Refer to TRANSMISSION FLUID COOLER FLUSHING AND FLOW TEST .
- Black in color
- Disassemble the transaxle and inspect for components that may have over heated.
- Inspect the transmission oil cooler system for functioning properly. Refer to TRANSMISSION FLUID COOLER FLUSHING AND FLOW TEST .
- Milky or white tint in color from coolant or water
- Inspect for failure of the transaxle oil cooler. Refer to ENGINE COOLANT/WATER IN TRANSMISSION .
- Inspect for missing or improperly routed vent hose.
- Inspect for missing fill plug.
- Excessively dirty with particles in the fluid
- Install the fluid level indicator.CAUTION: Refer to FASTENER NOTICE .
- Install the fluid indicator bolt.
Tightening torque
Tighten the fluid indicator bolt to 10 N.m (89 lb in).
