Can GMC service save me 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?

What triggers the malfunction indicator light (MIL) in a Sierra 3500 HD?

Engine problems, transmission problems, faulty sensors, electrical issues, misfire issues, and connector problems could all cause your Sierra 3500 HD’s malfunction warning light, or better known as the check engine light, to illuminate.

Can you clear the Sierra 3500 HD 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.

Does my Sierra 3500 HD transmission belong to the drivetrain system?

Yes, the transmission is an essential part of your Sierra 3500 HD’s drivetrain. The drivetrain consists of components — like the transmission — that transfer power from the engine to the wheels to move your Sierra 3500 HD forward. Other components in the driver train include the axles, differential, and driveshaft.
