2008 GMC Sierra 3500 HD Transmission Q&A

  • Is it bad to ride the brakes in your GMC? 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 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. 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.
  • When should I have my Sierra 3500 HD's transmission fluid checked or exchanged? Regularly checking and exchanging your 2008 Sierra 3500 HD’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 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.
