MAINTAINING YOUR VEHICLE 377 Lubricant Selection Getrag G56 (6-Speed Manual Transmission - If Equipped) This transmission is filled with manual transmission fluid at the factory. This fluid does not require periodic changing. If it is necessary to add or change fluid in this transmission refer to Recommended Fluids, Lubricants and Genuine Parts for correct fluid type. This is the only lubricant recommended for use in the Getrag G56 transmission. Automatic Transmission Fluid Level Check The fluid level should be checked when the engine is fully warmed up and the fluid in the transmission is at normal operating temperature. Operation of the transmission with an improper fluid level will greatly reduce the life of the transmission and of the fluid. Check the fluid level whenever the vehicle is serviced. Fluid Level Check - 45RFE/545RFE Check the fluid level while the transmission is at normal operating temperature 82°C (180°F). This occurs after at least 15 miles (25 km) of driving. At normal operating temperature the fluid cannot be held comfortably between the fingertips. 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). 7
