What do you get when you combine the convenience of Advance Auto Parts & Carquest and the quality of Shift Pro Remanufactured Transmissions? A darn good decision for you and your car.

From Shift Pro’s reputation for quality to Advance Auto Parts & Carquest’s reputations for service, you get fast, painless access to the best in remanufactured transmissions.

Teardown

In transmission remanufacturing, it all begins with a core. Each transmission core goes through our teardown department. There, it’s completely disassembled, cleaned, inspected, and prepped for the remanufacturing process.

Machining

To better control the quality of our transmissions, we custom machine as many parts as possible. From NT-spec bushings to modified valve bodies, our machining department helps ensure OE+ quality for each transmission.

Valve Body

Before the building process can resume, each valve body must be completely disassembled and thoroughly inspected. Every valve, plug, clip, and solenoid is guaranteed to meet or exceed OE specifications.

Building

This is where the magic happens. The parts, valve bodies, and subassemblies are masterfully combined to produce a completely remanufactured transmission.

Dyno Testing

Our custom-designed dyno testing program collects and processes more than 1,000,000 bytes of data from each transmission. Hot-testing, cold-testing and road-testing helps ensure a better-than-new, fully remanufactured transmission.
