What Is an Allison Retran?

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 a relentless commitment to quality and plays out in an ability to bring that transmission back to life using exclusively Allison Genuine Parts and under original factory build specs. Nothing gets you closer to brand new. And nobody knows an Allison, like Allison.
