412 MAINTAINING YOUR VEHICLE If you notice fluid loss or gear shift malfunction, have your authorized dealer check the transmission fluid level. To check the automatic transmission fluid level properly, the following procedure must be used: 1. Operate the engine at idle speed and normal operating temperature. 2. The vehicle must be on level ground. 3. Fully apply the parking brake and press the brake pedal. 4. Place the gear selector momentarily in each gear position ending with the lever in P (Park). 5. Remove the dipstick, wipe it clean and reinsert it until seated. 6. Remove the dipstick again and note the fluid level on both sides. The fluid level should be between the "HOT" (upper) reference holes on the dipstick at normal operating temperature. The fluid level is only valid if there is a solid coating of oil is seen on both sides of the dipstick. If CAUTION! The fluid level is preset at the factory and it does not require adjustment under normal operating conditions. If a transmission fluid leak occurs, visit your authorized dealer immediately. Severe damage to the transmission may occur. Your authorized dealer has the proper tools to adjust the fluid level accurately. Fluid Level Check (4.7L and 5.7L Engine) Check the fluid level while the transmission is at normal operating temperature. This occurs after at least 15 miles (25 km) of driving. At normal operating temperature the fluid cannot be held comfortably between the fingertips.
