FLUID LEVEL AND CONDITION

Check the fluid level and condition as follows:

1. Drive the vehicle until the transmission fluid is at a normal operating temperature of approximately 79.4°C (175°F).

NOTE: To avoid false readings, which could result in an over or under-fill condition, do not check the fluid level until the fluid is at operating temperature.

2. Shift the transmission into the Neutral position.

NOTE: The transmission fluid level is checked in Neutral because the converter fills more rapidly in this position.

3. Apply the parking brake.

4. Operate the engine at idle speed.

5. Wipe dirt from the filler cap and tube before removing the dipstick.

WARNING: Be sure to keep hands or loose articles of clothing away from the fan, accessory drive belts or other rotating engine parts. Contact with these components or hot engine components can result in personal injury.

6. Remove the dipstick and check the fluid level. The fluid level is correct when it is between the ADD ONE PINT and the FULL marks on the dipstick.

7. Add or drain the fluid as necessary to bring the fluid to the correct level. If the level was low, check the transmission for leaks.

8. Check the condition of the fluid.

- the fluid should be dark red in color and free of dirt or debris.

- if the fluid is discolored or smells burnt, but the transmission operates correctly, both the fluid and filter should be replaced.

- if the fluid is badly discolored, smells burnt, contains metal or frictional material particles and transmission problems were experienced, the transmission may require an overhaul.

9. A low fluid level allows the pump to take in air along with the fluid. As in any hydraulic system, aerated fluid will cause hydraulic pressures to be low and develop slower than normal.

10. If the transmission is overfilled, the gears churn the fluid into foam, aerating the fluid and causing the same conditions that occur with a low fluid level. In either case, air bubbles cause fluid overheating, oxidation and varnish buildup which interferes with valve, clutch and servo operation. Foaming can also result in fluid escaping from the transmission vent where it may be mistaken for a leak.

11. Along with the fluid level, it is also important to check the fluid condition. When the fluid is dark, smells burnt or is contaminated with metal or frictional material particles, an overhaul may be necessary. Examine the fluid on the dipstick closely. If there is any doubt about its condition, drain out a sample for further inspection.

12. After checking the fluid level and condition, seat the dipstick fully to seal out water and dirt.

NOTE: After completing any repairs that have involved draining the transmission fluid, add 4.5 liters (8 pints) of AMC/Jeep/Renault or equivalent Dexron II Automatic Transmission Fluid to the transmission before starting the engine.
