2018 Mercedes-Benz GLS450 Transmission Q&A

  • 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. Remember that when you’re driving down winding roads, and opt for engine braking when possible.
  • How much can I tow in a Mercedes-Benz GLS450? Think twice before offering to tow something for a friend, no matter how light the load might seem. The added load can mess with your transmission system if it exceeds your GLS450’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 GLS450 transmission fluid need to be checked? Caring for your Mercedes-Benz GLS450’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. The good news is that transmission fluid leaks are affordable to repair and easy to spot.
  • Can Mercedes-Benz GLS450 transmission fluid leak? Yes. Mercedes-Benz GLS450 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.
  • Where can I get my  Mercedes-Benz GLS450 transmission fixed? Your local Firestone Complete Auto Care can troubleshoot and repair GLS450 transmission systems. Book an appointment online today.
  • Is it okay to drive a GLS450 with a transmission fluid leak? Driving your GLS450 with a transmission fluid leak is highly discouraged. Transmission fluid is vital to the smooth operation of your transmission system, and a leak can put the entire system at risk. A transmission fluid leak may lead to decreased performance, overheating, and possibly even transmission failure.
