Allison ReTran®

Not Just Rebuilt. Reborn.

What makes an Allison™ ReTran® remanufactured transmission different from other rebuilds is the same thing that makes an original Allison fully automatic transmission unique. It starts with our relentless commitment to quality and plays out in our ability to bring that transmission back to life using exclusively genuine Allison parts and our original factory specs. Nobody gets you closer to brand new. And nobody knows an Allison, like Allison.

Our never-ending commitment to quality and innovation has driven the development of Allison as the leading producer of fully automatic transmissions. Since the beginning, our founder James A. Allison stated that quality was first and foremost. We have not forgotten why people rely on Allison, and that same philosophy is reborn with every ReTran.

What’s Inside a ReTran®?

Every genuine Allison ReTran® transmission is remanufactured from the ground up at the Allison Transmission remanufacturing facility. Here, transmissions are disassembled part-by-part to clean, qualify and test each component to screen for the possibility of reuse. New components needed for a ReTran® are always brand new, exclusively genuine Allison parts. Quality inside means you get a more reliable, dependable remanufactured transmission. It’s a promise you’ll only get with an authentic Allison ReTran®.

What’s Inside Others?

Who knows? After all, what’s inside a transmission is not readily visible from the outside. If you’re not specifying a ReTran®, you can’t really know what’s inside the transmission. It could be anything, from inferior parts to substandard machining to inadequate testing, and it all could be built into an imposter’s remanufactured transmission. Substandard efforts can put people, payloads and performance at risk, and short-term savings aren’t savings when they turn into long-term headaches.

Bringing it All Together

Allison Transmission guarantees that every part and every process associated with an Allison ReTran® is 100% authentic.

Only Allison ReTran remanufactured transmissions undergo our proprietary dynamometer testing to ensure they exactly meet the original factory specs. No other rebuilder has access to our Allison factory specs, process, or know-how. Every Allison ReTran is inspected for quality at each stage of the remanufacturing process, then measured against stringent wear-limit specs. The Allison ReTran checklist provides an overview of our proprietary work.
