1990 GMC G1500 Questions & Answers

  • Is it bad to ride the brakes in your GMC? Keeping your foot on the brake pedal or lightly but consistently pushing it down can lead to transmission problems. 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 a 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.
  • When should I have my G1500's transmission fluid checked or exchanged? Regularly checking and exchanging your 1990 G1500’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. Leaks or low transmission fluid are easy to spot and affordable to repair.
  • Can transmission fluid leak from my GMC G1500? Yes. GMC G1500 transmission fluid can leak as time passes, which may lead to transmission problems.
