1985 GMC S15 Transmission Q&A

  • What happens if I "ride" my GMC's brakes? Riding the brakes (keeping your foot lightly pressed on the brake pedal for a long time) can lead to transmission issues over time. Pay attention to how often you apply your brake and use engine braking when possible.
  • How much can my GMC tow?   Think twice before offering to tow something for a friend, no matter how small. The added load can mess with your transmission system if it exceeds your S15’s towing capacity. Always consult your owner's manual before towing or hauling something.
  • When should I have my S15's transmission fluid checked or exchanged? Regularly checking and exchanging your 1985 S15’s transmission fluid is one of the best ways to help the transmission system 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.
  • Can GMC S15 transmission fluid leak? Yes, your GMC S15 can develop a transmission fluid leak. As your S15 ages, parts of the transmission system might wear out or break down, leading to a leak and possible transmission issues. Common causes of transmission fluid leaks include worn seals, a damaged transmission housing, a loose or cracked transmission pan, an overfilled transmission, or faulty transmission lines.

  • Should I avoid driving my GMC S15 if there is a transmission fluid leak? Driving your S15 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.
