Checking Transaxle Fluid Hot

FLUID CHECK (HOT) 4T80-E TRANSAXLE

NOTE: Wait at least 30 minutes before checking transaxle fluid if the vehicle has been driven when the outside temperature is above 90° F, at high speed for an extended period of time and/or in heavy traffic (especially in hot weather). To obtain an accurate reading, the fluid must be at normal operating temperature (180°-200°F). Bring the vehicle up to operating temperature by driving about 15 miles when outside temperature is above 50° F.

1. Park vehicle on level surface, then place shifter in Park.

2. Apply brake, move shifter through each gear range, pausing for three seconds in each range, then place shifter in Park.

3. Apply parking brake, then allow engine to idle for three to five minutes.

4. For remainder of test, shifter should be in Park, parking brake should be applied and foot brake should NOT be on applied (foot brake will affect oil level).

5. Remove dipstick and wipe clean, then insert dipstick for three seconds and pull out.

6. Check both sides of dipstick. Fluid level on lower side must be in hot range of indicator.

7. If level is in hot range, no level adjustment is necessary.

8. If level is not in hot range, add fluid until level reaches middle of hot range.
