2012 GMC Sierra 2500 HD Transmission Q&A

  • 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. Remember that when you’re driving down winding roads, and opt for engine braking when possible.
  • How much can my GMC tow?   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 HD’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 2500 HD's transmission fluid checked or exchanged? Maintaining your GMC Sierra 2500 HD transmission fluid is one of the best ways to maintain your transmission's health. 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.
  • Can transmission fluid leak from my GMC Sierra 2500 HD? Yes. GMC Sierra 2500 HD transmission fluid can leak over time and potentially cause transmission issues.
