434 MAINTAINING YOUR VEHICLE Fluid Level Check (3.7L and 3.0L Diesel Engine) Regular fluid level checks are not required. For this reason, the dipstick is omitted. If you notice fluid loss or shift lever malfunction, have your authorized dealer check the transmission fluid level. CAUTION! (Continued) • 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. To check the fluid level properly, the following procedure must be used: 1. Operate the engine at idle speed and normal operating temperature. CAUTION! • Using a transmission fluid other than the manufacturer's recommended fluid may cause deterioration in transmission shift quality and/or torque converter shudder. Using a transmission fluid other than that recommended by the manufacturer will result in more frequent fluid and filter changes. Refer to "Fluids, Lubricants, and Genuine Parts" in this section for the correct fluid type. (Continued)
