What are signs my GMC drivetrain is damaged?

Noises toward the back of your GMC G3500, leaking fluid, trouble turning — these could all be signs of drivetrain damage you want to address. Take action before something more severe happens.

When should I come in for GMC G3500 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 my G3500 malfunction indicator light (MIL) on?

Can my G3500 malfunction warning light be reset at home?

While resetting a malfunction warning light at home is technically possible, doing so is not advisable. The check engine light is typically a sign of a problem in one of your G3500's systems, and simply resetting the light will not address the underlying issue. Instead, you should bring your vehicle to a reliable auto shop to have the underlying problem identified and fixed to help ensure the safety and reliability of your G3500.

How worried should I be about a drivetrain malfunction in my G3500?

If your G3500 has a drivetrain malfunction, don't wait. Get it checked out by a professional mechanic. Identifying the underlying cause and performing the appropriate repairs right away can help prevent further damage and avoid unsafe driving conditions.

Does my G3500 transmission belong to the drivetrain system?

Yes, the drivetrain system in your G3500 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 G3500 forward.
