Can GMC service save me money?

Yes, sometimes it can. First, servicing the drivetrain system can help you avoid more significant repairs. It can also somewhat reduce tire wear.

How do I know if my GMC drivetrain is damaged?

Your GMC C3500 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 C3500 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.

What triggers the malfunction indicator light (MIL) in a C3500?

If your C3500 has its malfunction warning light (more commonly called the check engine light) illuminated, it could indicate engine troubles, problems with the transmission, electrical issues, malfunctioning sensors, connector problems, or misfire issues.

Can you clear the C3500 check engine light on your own?

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 C3500'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 C3500.

How serious is a drivetrain malfunction in my C3500?

If your C3500 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 C3500 transmission belong to the drivetrain system?

Yes, the transmission is an essential part of your C3500’s drivetrain. The drivetrain consists of components — like the transmission — that transfer power from the engine to the wheels to move your C3500 forward. Other components in the driver train include the axles, differential, and driveshaft.

What Does the Drivetrain Do In Your 1985 GMC C3500

The drivetrain is responsible for transferring power from your C3500's engine to its wheels. It spans the full length of your GMC, from back to front. It’s a very intricate system of moving parts and is comprised of everything after the engine transmission: driveshafts, axles, joints, differentials, and wheels. When you maintain the drivetrain in your 1985 GMC C3500, you help maintain your vehicle's power. Follow GMC's recommendations for lubricating bearings/gears and checking/changing differential fluids to minimize repairs over time.
