FLUID LEVEL CHECK
See Figures 1 through 5
Too little or too much fluid will impair the proper operation of the automatic transmission. The fluid level should be checked regularly (see "Maintenance Intervals") by using the transmission dipstick, which is accessible through the engine compartment. During this check, the car should be on a level surface and the engine and transmission should be at normal operating temperature.
- Apply the parking brake.
- Move the selector lever into the Park position.
- Run the engine at normal operating temperature.
- Remove the dipstick and wipe it with a clean, lint-free rag.
Some automatic transmissions have a clamp lock that must be released; others do not.
- Insert the dipstick, remove it again, and read the fluid level.
- With a correct fluid level and a warm transmission, the fluid level should be at the upper marking or at least between the two marks.
The fluid level will change with temperature. The "min" and "max" marks on the dipstick apply when the fluid is hot, after 5 minutes driving. When the fluid is cold, the fluid level will be approximately 1 in. below the minimum mark.
- Additional oil (use only Dexron B) can be added through the dipstick guide (engine running) by using a funnel. Be careful not to add too much fluid. As a rough guide, there is approximately 0.3 quart between the maximum and minimum dipstick markings.
DRAIN & REFILL
See Figures 6 through 12
Before attempting to drain the transmission fluid, be sure that the vehicle is on level ground and that the transmission is at normal operating temperature. The engine should be shut off.
- Drain the fluid from the transmission either by removing the filler pipe under the transmission or by removing the drain plug.
- Observe the same safety precautions as are listed for "Engine Oil Changes," regarding hot oil and safety.
- When all the fluid is drained, remove the transmission oil pan. Be sure the filler pipe is disconnected.
- Replace the oil filter, making sure that all bolts are tightened. The oil filter should not be cleaned, but replaced with a new one.
- Clean the inside of the pan with a clean lint-free rag.
- Install the oil pan.
- Install the filler pipe or drain plug using new washers or gaskets in each case.
- Insert a funnel with a fine mesh strainer into the dipstick tube and add a large portion (not all) of the transmission oil capacity. This should be done with the engine stopped.
- Start the engine and run it at idle speed with the selector lever in Park. Gradually add the remaining fluid. Do not overfill the transmission.
- Check the oil level with the transmission at operating temperature.
- Be sure to remove any excess fluid.
