MAINTAINING YOUR VEHICLE 355 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 Dodge Dealer or Service Center. It is important that proper lubricant is used in the transmission. Refer to Recommended Fluids, Lubricants and Genuine Parts for correct fluid type. 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(s) should be changed. Special Additives The manufacturer strongly recommends against the addition of any additives to the transmission. Exception to this policy is the use of special dyes to aid in detecting fluid leaks. The use of transmission sealers should be avoided, since they may adversely affect seals. Front Wheel Bearings Front wheel bearings for all Dodge Ram Trucks are sealed-for-life. They do not require greasing or seal replacement. In some instances, these bearings will "purge" excess grease and the bearing will look slightly wet. This is normal. Periodic inspection for excess play is recommended. Rear Wheel Bearings - Manufacturer's Axles These bearings are normally considered permanently lubricated. Cleaning and repacking is required only when axle shafts are removed or in case of extreme water or dust contamination. 7
