Fluid Level Checking Procedure
1990 Chevrolet Lumina APV V6-191 3.1LSECTION Fluid Level Checking Procedure
Fig. 2 Transaxle Dipstrick Oil Level Readings:
The transmission oil level should be approximately 1/2 inch above the ``FULL'' mark at room temperature (65°-85°F), or between the two dimples on the dipstick, Fig. 2. The oil level at normal operating temperature (190°-200°F) should be between the ``ADD'' and ``FULL'' marks. The vehicle must be driven at least 15 minutes to allow the transmission oil to reach normal operating temperature. To bring the oil level from the ADD mark to the FULL mark requires approximately one pint of fluid. Check oil level with vehicle on level surface, parking brake applied, engine idling at operating temperature and transmission in Park.
If additional fluid is required, use only Dexron II or Dexron IIE automatic transmission fluid. When adding fluid, do not overfill, as foaming and loss of fluid through the vent may occur as the fluid heats up. Also, if fluid level is too low, complete loss of drive may occur especially when cold, which can cause transmission failure.
