Questions About 1986 Mercedes-Benz 420SEL’s Transmission

  • What happens if I "ride" my Mercedes-Benz's brakes? Riding the brakes (keeping your foot lightly pressed on the brake pedal for a long time) can lead to transmission issues over time. Keep that in mind when driving in hilly terrain and remember to use engine braking when possible.
  • How much can my Mercedes-Benz tow?   Think twice before offering to tow something for a friend, no matter how small it is. The added load can mess with your transmission system if it exceeds your 420SEL’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 420SEL transmission fluid need to be checked? Caring for your Mercedes-Benz 420SEL’s transmission fluid is a great way to help it perform. A general rule of thumb is to have your transmission fluid checked and changed about every 30,000 to 60,000 miles, but that timeline can change if you're hard on your Mercedes-Benz. Leaks or low transmission fluid are easy to spot and affordable to repair.
  • Can Mercedes-Benz 420SEL transmission fluid leak? Yes. Mercedes-Benz 420SEL transmission fluid can leak over time and potentially cause transmission issues. Worn or damaged seals, a loose or damaged transmission pan, a cracked transmission housing, faulty transmission cooler lines, or an overfilled transmission could cause transmission fluid leaks.

You might even experience transmission failure.
