Allison Retran®

An Allison ReTran is the closest you will get to brand new without the costly purchase of a new transmission.  Through the Allison ReTran process, technicians bring transmissions back to life following original factory specifications, using only Allison Genuine Parts where new parts are needed.

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

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

Every genuine Allison ReTran® comes with two years of unlimited mileage worldwide service coverage.* Additional 2-Year Extended Transmission Coverage (ETC) is also available for purchase.
