MAINTAINING YOUR VEHICLE 425 Automatic Transmission Fluid Level Check Your vehicle is equipped with a capped dipstick tube that is sealed and it should not be tampered with. Your authorized dealer has the proper tools to ensure that the fluid level is set properly. Fluid and Filter Changes Change the automatic transmission fluid and filter at the intervals shown in the "Maintenance Schedule" in Section 8 of this manual. In addition, change the fluid and filter if the transmission is disassembled for any reason. NOTE: Be sure to follow the "police, taxi, fleet, off-road, or frequent trailer towing" maintenance interval if applicable. Special Additives Automatic Transmission Fluid (ATF) is an engineered product and its performance may be impaired by supplemental additives. Therefore, do not add any fluid additives to the transmission. The only exception to this policy is the use of special dyes to aid in detecting fluid leaks. In addition, avoid using transmission sealers as they may adversely affect seals. 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. 7
