1991 Mercedes-Benz 420SEL Questions & Answers

  • What happens when you "ride" your 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 volunteering to tow a moving trailer, no matter how small it is. The added weight can cause issues with your transmission if your vehicle isn't equipped to handle the load. Always consult your owner's manual before towing or hauling something.
  • When should I have my 420SEL's transmission fluid checked or exchanged? Caring for your Mercedes-Benz 420SEL’s transmission fluid is a great way to help it 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. Luckily, leaks and low fluid levels are easy to spot and inexpensive to fix.
  • Can transmission fluid leak from my Mercedes-Benz 420SEL? 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.

A transmission fluid leak may lead to decreased performance, overheating, and possibly even transmission failure.
