The automatic transaxle fluid level should be checked at each engine oil change. When adding or changing the automatic transaxle fluid use only fluid labeled Dexron®Ii or iie.

  1. Set the parking brake and start the engine with the transaxle in P (Park).

With the service brakes applied, move the shift lever through all the gear ranges, ending in P (Park).

The fluid level must be checked with the engine running at slow idle, with the car level, and the fluid at least at room temperature. The correct fluid level cannot be read if you have just driven the car for a long time at high speed, city traffic in hot weather or if the car has been pulling a trailer. In these cases, wait at least 30 minutes for the fluid to cool down.

  1. Remove the dipstick located at the rear end of the engine compartment, wipe it clean, then push it back in until the cap seats.
  3. Pull the dipstick out and read the fluid level. The level should be in the cross-hatched area of the dipstick.
  5. If necessary, add fluid using a long plastic funnel in the dipstick tube. Keep in mind that the pan is flat, and a small amount of fluid will raise the level on the dipstick quickly.

Damage to the automatic transaxle may result if the fluid level is above the hatched area. Remove excess fluid by threading a small rubber hose into the dipstick tube and pumping the fluid out with a siphon pump.
