Allison authorized for overhaul

There are many authorized Allison dealers rebuilding Allison transmissions, but not all are authorized for overhaul. And there are many rebuilders not authorized at all. As a full service Allison dealer, RTS is authorized for Overhaul.

And because we are an Allison Overhaul dealer, customers are assured that we build our transmissions USING ONLY Allison Genuine Parts™ , performing engineering updates, meeting FTC guidelines, and more. So you can trust our brand of reman Allisons have been built right.

Warranty and Availability

We believe that the best warranty is the one never used, and ours rarely is. While there may be longer warranties without extra cost, as a fleet maintenance manager, what’s the cost in downtime and operational consequences when that Allison reman goes down one or more times? RTS believes a remanufactured transmission should be built and operate like a brand new transmission, and after 40 years, you can trust ours live up to that standard. That’s why we issue our “Good as Gold” warranty with every Allison reman we build. And with a reserve inventory of 300+ remanufactured Allison transmissions and a production inventory of 500+ Allison transmissions, we are ready to serve you nationwide.
