Questions About 2018 GMC Sierra 3500 HD’s Transmission

  • What happens if I "ride" my GMC'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 GMC Sierra 3500 HD? Think twice before offering to tow something for a friend, no matter how small. The added weight can cause issues with your transmission if your vehicle isn't equipped to handle the load. Double check your owner's manual to ensure your Sierra 3500 HD is equipped with a towing setup and can handle whatever you're thinking about towing.
  • Does my Sierra 3500 HD's transmission fluid need to be inspected? Caring for your GMC Sierra 3500 HD’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 GMC. The good news is that transmission fluid leaks are affordable to repair and easy to spot.
  • Can transmission fluid leak from my GMC Sierra 3500 HD? Yes. GMC Sierra 3500 HD 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.

  • Should I avoid driving my GMC Sierra 3500 HD if there is a transmission fluid leak? You should avoid driving with a transmission fluid leak. Your transmission system relies on transmission fluid to operate properly, and a leak may decrease performance, cause your Sierra 3500 HD to overheat, or even lead to transmission failure.
