How does GMC drivetrain maintenance help save money?

Servicing the drivetrain system can help you save money by saving other parts of your vehicle. A bad drivetrain can put undue stress on other vehicle parts and lead to premature wear and tear.

What are signs my GMC drivetrain is damaged?

Your GMC S15 drivetrain might be damaged if you notice strange noises from the rear of your vehicle, see fluid leaking, or have issues turning.

How often will I need GMC S15 differential service?

Differential service frequency varies from car to car. Double check your owner’s manual and talk with a technician. We generally recommend getting your differential inspected and the differential fluid changed as a part of your regular vehicle maintenance routine since your vehicle cannot function without a differential.

Why is my S15 malfunction indicator light (MIL) on?

The malfunction indicator light — also known as the check engine light — on your S15 can illuminate for a variety of reasons, including engine issues, electrical problems, damaged sensors, transmission problems, misfires, and faulty connections.

Is it possible to reset the S15 malfunction warning light on my own?

Resetting a malfunction warning light at home may be possible sometimes, but it is never recommended. The check engine light is commonly triggered by a misfire, fault or malfunction in one of the vehicle's systems. It is important to identify and fix the underlying problem to ensure the safety and reliability of the vehicle. Resetting the check engine light without addressing the underlying issue may temporarily remove the warning, but it will not fix the root cause of the problem.

How worried should I be about a drivetrain malfunction in my S15?

Don't ignore a drivetrain malfunction in your S15. As soon as you notice a problem, have it checked by a professional mechanic to diagnose the issue and carry out any necessary repairs. Driving with a faulty drivetrain is risky and may further damage your S15.

Does my S15 transmission belong to the drivetrain system?

Yes, the drivetrain system in your S15 includes the transmission. Other components in the drivetrain are the driveshaft, axles, and differential. Together, these components deliver power from the engine to the wheels to push your S15 forward.
