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.

What are the symptoms of a damaged GMC drivetrain system?

Noises toward the back of your GMC G1500, 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 G1500 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.

Why is the malfunction indicator light (MIL) on in my G1500?

The malfunction indicator light — also known as the check engine light — on your G1500 can illuminate for a variety of reasons, including engine issues, electrical problems, damaged sensors, transmission problems, misfires, and faulty connections.

Can you clear the G1500 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 worried should I be about a drivetrain malfunction in my G1500?

Don't ignore a drivetrain malfunction in your G1500. 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 G1500.

Is my G1500’s transmission part of the drivetrain?

Yes, the transmission is an essential part of your G1500’s drivetrain. The drivetrain consists of components — like the transmission — that transfer power from the engine to the wheels to move your G1500 forward. Other components in the driver train include the axles, differential, and driveshaft.
