I would not do what they say that bothers me. If it worked fine the first time maybe check the fluid and I am not sure if it has a kickdown thats cable or linkage but make sure thats hooked up and adjusted correctly. The cable could be bent or binding in the sheath or the linkage could be stuck. The 727s I have delt with had manual valve bodies. If it drove fine before its gotta be something easy hopefully.
