Do I need upgrades for towing?
For heavy-duty transmission rebuilds, components are selected to address documented platform-specific wear points and known failure areas. Reputable aftermarket billet components are used where functional improvement is required.
Typical upgrades may include billet channel plates, upgraded servos and accumulators, reinforced shafts, and billet-backed torque converters. Each component is selected based on application requirements, documented in the build plan, and installed using measured specifications to support durability and consistent operation.

Heavy-Duty Transmission Questions, Answered
What is a heavy-duty transmission rebuild?
A heavy-duty rebuild goes beyond a standard transmission rebuild by incorporating selected components and upgrades designed to better handle increased load, heat, towing, hauling, or other demanding driving conditions. The exact build depends on the transmission, vehicle, and intended use.
Do I need a heavy-duty transmission for towing?
Not every truck needs an upgraded transmission. We consider your vehicle, towing weight, driving habits, transmission type, and how frequently you tow to recommend a build that fits how you actually use your truck.
What heavy-duty transmission options do you offer?
Gears offers different build options for towing, heavy-use, and performance applications. Because every application is different, we can help determine which internal components and upgrades make sense for your specific vehicle.
Do you rebuild heavy-duty transmissions in-house?
Yes. Our transmission rebuilds are completed in-house at our facility, allowing our team to oversee the teardown, inspection, rebuilding, installation, and quality-control process.
Can you build transmissions for diesel trucks?
Yes. We offer transmission rebuild and upgrade options for many Cummins, Power Stroke, and Duramax applications, including trucks used for towing, hauling, work, and performance.
Are your heavy-duty transmission rebuilds covered by a warranty?
Warranty coverage depends on the specific build and application. Qualifying transmission rebuilds include a 3-year/100,000-mile nationwide warranty through the ATRA Network. Our team will explain the applicable warranty coverage before repairs begin.
