It means everything to me. I have no idea if the guy selling me a used trans had previously dropped it or not and it ends up having a cracked case? Why would you sell a used T56 Magnum anyways as they are great transmissions that anyone would want, unless there is something wrong with it and that person selling needed to get rid of it. Used parts work for you and thats awesome! More power to you as well as cash in your wallet. I just personally do not trust any used parts.

With a brand new trans, everything is 100% good which leaves no doubt. Parts also have a finite life span as well. Nothing raced and abused lasts forever.
