2003 GMC Sierra 2500 Questions & Answers

  • What happens when you "ride" your 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. Pay attention to how often you apply your brake and use engine braking when possible.
  • What can I tow in a GMC? Think twice before volunteering to tow your friend's moving trailer, no matter how light the load might seem. The added load can mess with your transmission system if it exceeds your Sierra 2500’s towing capacity. Double check your owner's manual to ensure your Sierra 2500 is equipped with a towing setup and can handle whatever you're thinking about towing.
  • Does my Sierra 2500's transmission fluid need to be inspected? Regularly checking and exchanging your 2003 Sierra 2500’s transmission fluid is one of the best ways to help the transmission system perform. 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. The good news is that transmission fluid leaks are affordable to repair and easy to spot.
  • Can transmission fluid leak from my GMC Sierra 2500? Over time, transmission fluid can leak from your GMC Sierra 2500, potentially causing transmission problems.
