Maybe you should look for a new transmission shop instead...It can be done . Your best bet is to look for a truck in the salvage yard and transfer everything that way . Yes it is alot of work but I know what your after . I'm tired of these horrible automatics that we have in some of these trucks . Mine has never been off roaded , serviced at regular intervals if not sooner and now I'm on my way to my 4th rebuild . I've had enough . I'm looking for a donor as we speak .
