1999 GMC Sierra 1500 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. 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. 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.
  • How often does my Sierra 1500 transmission fluid need to be checked? Caring for your GMC Sierra 1500’s transmission fluid is a great way to help it perform. 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.
  • 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.

  • Is it okay to drive a Sierra 1500 with a transmission fluid leak? Driving your Sierra 1500 with a transmission fluid leak is highly discouraged. Transmission fluid is vital to the smooth operation of your transmission system, and a leak can put the entire system at risk. A transmission fluid leak may lead to decreased performance, overheating, and possibly even transmission failure.
