Questions About 1990 GMC S15’s Transmission

  • 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. 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? Maintaining your GMC S15 transmission fluid is one of the best ways to maintain your transmission's health. 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. Luckily, leaks and low fluid levels are easy to spot and inexpensive to fix.
  • Can my GMC S15 leak transmission fluid? Yes. GMC S15 transmission fluid can leak as time passes, which may lead to transmission problems. Transmission fluid leaks are often caused by worn or damaged transmission components, such as the transmission pan, cooler lines, seals, or housing.
