Questions About 2003 GMC Sierra 1500’s Transmission

  • What happens when you "ride" your GMC's brakes? Keeping your foot on the brake pedal or lightly but consistently pushing it down can lead to transmission problems. 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 small it is. The added weight can cause issues with your transmission if your vehicle isn't equipped to handle the load. Check your owner's manual to ensure you have the proper towing setup and aren't going over your towing capacity.
  • Does my Sierra 1500's transmission fluid need to be inspected? Regularly checking and exchanging your 2003 Sierra 1500’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. 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 1500? Yes. GMC Sierra 1500 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.
  • Who fixes GMC Sierra 1500 transmission leaks? When your Sierra 1500 transmission is acting up, Firestone Complete Auto Care is here to help. Book an appointment today for transmission system diagnostics and repairs.
  • Should I avoid driving my GMC Sierra 1500 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 1500 to overheat, or even lead to transmission failure.
