The MT643RM is the remanufactured MT that Allison sold. It was remanufactured to Allison specs at a contract remanufacturer. The data tag should also say ReTran somewhere on it.

Remanufactured makes sense. Was a little puzzled, thought it might mean Retarder model but picture I was looking at clearly showed no retarder. Thanks
