Check the level of the automatic transmission fluid every 2,000 miles.

The electric cooling fan, on front wheel drive models, may switch at any time the engine is running. Keep hands away.

The dipstick has a high and low mark which are accurate for level indications only when the transmission is hot (normal operating temperature). The transmission is considered hot after 15 miles of highway driving.

  1. Park the car on a level surface with the engine idling. Apply the parking brake.
  3. Shift the transmission through all ranges and return the lever to the PARK position.
  5. Remove the dipstick wipe it clean, then reinsert it firmly. Be certain that it has been pushed fully home. Remove the dipstick and check the fluid level while holding the dipstick horizontally. The level should be at or near the high mark.
  7. If the fluid level is below the low mark, add Dexron®II type automatic transmission fluid through the dipstick tube. This is more easily accomplished with the aid of a funnel and hose. Check the level often between additions, being careful not to overfill the transmission. Overfilling will cause slippage, seal damage, and overheating. Approximately one pint of fluid will raise the level from low to high.
