Fluid - A/T: Testing and Inspection
Fluid Checking Procedure:
4L6O-E TRANSMISSION FLUID CHECKING PROCEDURE
1. Warm the transmission to operating temperature by driving the vehicle about 15 miles (24 km). Operating temperature is 82-94° C (180-200° F).
2. Park vehicle on a level surface place shift lever in park and apply the parking brake.
3. Check fluid level on the dipstick (read the lower level).
4. If fluid level is low DEXRON -III Automatic Transmissions Fluid is preferred if unavailable DEXRON -IIE is acceptable, add only enough to bring the fluid level into the hot area.
NOTE: It is important to check fluid level when the transmission has reached operating temperature. The hot range is calibrated to correspond to the correct fluid level range for fluid between 82-94° C (180-200° F).
