Check the level of the transmission fluid every 3,000 miles (4,800 km) and replace it every 15,000 (24,000 km) miles or 12 months. It is important that these figures be adhered to, in order to ensure a long transmission life. The procedures for checking the oil are given as follows:
Start the engine and allow to idle for a few minutes. Set the hand brake and apply the service brakes. Move the gear selector through all ranges.
With the engine still running, the parking brake on and the wheels blocked, place the selector in Neutral. Remove and clean the dipstick. Insert the dipstick fully, remove it and take a reading. The dipstick has two ranges.
- COLD The fluid level should fall in this range when the engine has been running for only a short time.
- HOT The fluid level should fall in this range when the engine has reached normal running temperatures.
- Replenish the fluid through the filler tube with type F fluid for all models built until July, 1983; Dexron®II for all models built beginning July 1983. Models using Dexron®II have a DII stamped on the pan or drain plug. Add fluid to the top of the COLD or HOT range, depending upon engine temperature.
DRAIN & REFILL
When your vehicle is equipped with an automatic transmission and the region in which you live has severe cold weather, a multi-viscosity automatic transmission fluid should be used. Ask your auto parts retailer about the availability of MV Automatic Transmission Fluid.
Use of fluid other than specified could result in transmission malfunctions and/or failure.
- Raise the car and safely support it on jackstands.
- Place a suitable drain pan underneath the transmission oil pan. Loosen the oil pan mounting bolts and allow the fluid to drain until it reaches the level of the pan flange. Remove the attaching bolts, leaving one end attached so that the pan will tip and the rest of the fluid will drain.
- Remove the oil pan. Thoroughly clean the pan. Remove the old gasket. Make sure that the gasket mounting surfaces are clean.
- Remove the transmission filter screen retaining bolt. Remove the screen.
- Install a new filter screen and O-ring. Place a new gasket on the pan and install the pan to the transmission.
- Fill the transmission to the correct level. Remove the jackstands and lower the car to the ground.
