Questions About 2020 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. Keep that in mind when driving in hilly terrain and remember to use engine braking when possible.
  • How much can my GMC tow?   Think twice before volunteering to tow a moving trailer, no matter how light the load might seem. Defying your Sierra 3500 HD towing capacity can spell trouble for the transmission system. 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.
  • How often does my Sierra 3500 HD transmission fluid need to be checked? 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. Luckily, leaks and low fluid levels are easy to spot and inexpensive to fix.
  • Is it possible for transmission fluid to leak from my GMC Sierra 3500 HD? Yes. GMC Sierra 3500 HD transmission fluid can leak as time passes, which may lead to transmission problems. Transmission fluid leaks are often caused by worn or damaged transmission components, such as the transmission pan, cooler lines, seals, or housing. An overfilled transmission may also be behind your transmission fluid leak.
