Well I can tell you that I have replaced many of the them with remanufactured units over the years working at the dealership. With that I can tell you that some where better than other's. But the only thing that ever killed that transmission was the check valve in the cooler line that would stick shut. Some did come with the larger overdrive unit that just have more clutches than others but they were all great units. If it's a replacement transmission the only way to tell what is in it would be to disassemble it and see.
