Genuine Allison ReTran® automatic transmissions are meticulously remanufactured to precise factory tolerances with original and new, improved Allison parts. Factory-trained technicians using Allison-approved technologies and manufacturing processes literally remake a genuine Allison transmission from the ground up. Transmissions are torn down piece by piece, cleaned and screened for possible reuse of components. Torque converters are disassembled, cleaned, qualified, reassembled and then tested to make sure they adhere to original Allison specifications.
Parts that meet original specs can be reused. Parts in good condition but outdated are machined to updated specs. And many of the components in an Allison ReTran® are brand new parts. All of the components are Genuine Allison Parts. From the first part to the final bolt, our remanufacturing process assures quality control unparalleled in the remanufacturing industry.
