450 MAINTAINING YOUR VEHICLE Automatic Transmission Fluid and Filter Change To obtain best performance and long life for automatic transmissions, the manufacturer recommends that they be given regular maintenance service by an authorized dealer or Service Center. It is important that the transmission fluid is maintained at the correct level, and that it is drained and refilled as specified. Use only manufacturer's recommended transmission fluid; for correct fluid type, refer to "Automatic Transmission" under "Fluids, Lubricants and Genuine Parts" in this section. It is important that the transmission fluid be maintained at the prescribed level using the recommended fluid.. The fluid and filter(s) should be changed as specified in the Maintenance Schedule (Section 8). NOTE: If the transmission is disassembled for any reason, the fluid and filter should be changed. 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. Front Wheel Bearings Front wheel bearings for your vehicle are sealed-for-life. They do not require greasing or seal replacement. In some instances, these bearings will "purge" excess grease and the bearing housing will look slightly wet. This is normal. • Periodic inspection for excess play is recommended. • If a bearing assembly is accidentally separated when servicing the brake rotors, it should be replaced.
