312 MAINTAINING YOUR VEHICLE To check the automatic transmission fluid level properly, the following procedure must be used: 1. The vehicle must be on level ground. 2. The engine should be running at curb idle speed for a minimum of 60 seconds. 3. Fully apply parking brake. 4. Apply the brakes and shift the transmission into P (Park). 5. The fluid MUST be checked with the transmission in P (Park) to be sure that the fluid level is accurate. 6. Wipe the dipstick clean and reinsert until seated. Remove dipstick and note reading. At normal operating temperature (approximately 180° F (82° C), the fluid level is correct if it is in the HOT region (cross-hatched area) on the oil level indicator. The fluid level indicator should be in the COLD region at 70° F (21° C) fluid temperature. If the fluid level is low, add sufficient fluid to bring to the proper level. Refer to Recommended Fluids, Lubricants and Genuine Parts for correct fluid type. Fluid is added through the dipstick tube. NOTE: To prevent dirt and water from entering the transmission after checking or replenishing fluid, make certain that the dipstick cap is properly reseated. Special Additives The manufacturer recommends against the addition of any additives to the transmission. Exception to this policy is the use of special dyes to aid in detecting fluid leaks.
