Can GMC drivetrain maintenance help me 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.

How do I know if my GMC drivetrain is damaged?

Noises toward the back of your GMC S15, leaking fluid, trouble turning — these could all be signs of drivetrain damage you want to address. Take action before something more severe happens.

How often will I need GMC S15 differential service?

Double check your owner’s manual and talk with a technician. Differential service frequency varies from car to car. At a minimum, we 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.

What triggers the malfunction indicator light (MIL) in a S15?

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.

Can you clear the S15 check engine light on your 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 serious is a drivetrain malfunction in my S15?

A drivetrain malfunction in your S15 should never be taken lightly. Driving with a malfunctioning drivetrain can put you in danger and lead to further vehicle damage, so it's essential to have a qualified mechanic assess and repair the problem as soon as possible.

Is my S15’s transmission part of the drivetrain?

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.

Follow GMC's recommendations for lubricating bearings/gears and checking/changing differential fluids to minimize repairs over time.
