1999 Mercedes-Benz S420 Questions & Answers

  • What happens if I "ride" my Mercedes-Benz's brakes? Keeping your foot on the brake pedal or lightly but consistently pushing it down can lead to transmission problems. Pay attention to how often you apply your brake and use engine braking when possible.
  • How much can I tow in a Mercedes-Benz S420? Think twice before volunteering to tow your friend's moving trailer, no matter how light the load might seem. The added load can mess with your transmission system if it exceeds your S420’s towing capacity. Check your owner's manual to ensure you have the proper towing setup and aren't going over your towing capacity.
  • How often does my S420 transmission fluid need to be checked? Regularly checking and exchanging your 1999 S420’s transmission fluid is one of the best ways to help the transmission system perform. About every 30,000 to 60,000 miles is a good timeframe for having your transmission fluid inspected and perhaps changed. Service intervals can vary depending on how you use your Mercedes-Benz, so check with your technician first. Leaks or low transmission fluid are easy to spot and affordable to repair.
  • Can my Mercedes-Benz S420 leak transmission fluid? Yes, your Mercedes-Benz S420 can develop a transmission fluid leak. As your S420 ages, parts of the transmission system might wear out or break down, leading to a leak and possible transmission issues. Common causes of transmission fluid leaks include worn seals, a damaged transmission housing, a loose or cracked transmission pan, an overfilled transmission, or faulty transmission lines.
