Questions About 2003 GMC Sierra 3500’s Transmission

  • What happens if I "ride" my GMC's brakes? Riding the brakes or keeping your foot on the brake pedal (even lightly) can lead to transmission issues. Pay attention to how often you apply your brake and use engine braking when possible.
  • How much can my GMC tow?   Think twice before volunteering to tow your friend's moving trailer, no matter how small. The added load can mess with your transmission system if it exceeds your Sierra 3500’s towing capacity. Check your owner's manual to ensure you have the proper towing setup and aren't going over your towing capacity.
  • When should I have my Sierra 3500's transmission fluid checked or exchanged? Maintaining your GMC Sierra 3500 transmission fluid is one of the best ways to maintain your transmission's health. Some technicians would say that between 30,000 and 60,000 miles is a good timeframe for having your GMC's transmission fluid checked and replaced, but that timeline can vary depending on how your vehicle is used and your manufacturer’s recommendations. Leaks or low transmission fluid are easy to spot and affordable to repair.
  • Is it possible for transmission fluid to leak from my GMC Sierra 3500? Yes. GMC Sierra 3500 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.
