Questions About 1986 GMC S15’s Transmission

  • What happens when you "ride" your GMC's brakes? Keeping your foot on the brake pedal or lightly but consistently pushing it down can lead to transmission problems. 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 light the load might seem. Defying your S15 towing capacity can spell trouble for the transmission system. Check your owner's manual to ensure you have the proper towing setup and aren't going over your towing capacity.
  • Does my S15's transmission fluid need to be inspected? Caring for your GMC S15’s transmission fluid is a great way to help it perform. About every 30,000 to 60,000 miles is a good timeframe for having your transmission fluid inspected and perhaps changed. Service intervals can vary depending on how you use your GMC, so check with your technician first. 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 S15? 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.

  • Can I still drive my GMC S15 if it has a transmission fluid leak? You should avoid driving with a transmission fluid leak. Your transmission system relies on transmission fluid to operate properly, and a leak may decrease performance, cause your S15 to overheat, or even lead to transmission failure.
