    2004 530i 6hp19 trans question

    Hello this is my first time here so please forgive me if this is been asked but I couldn稚 find anything in the search. I知 looking for some professional insight on a transmission issue. I have a 2004 530i that I purchased for my son a few months ago ran and drove fine but was burning oil at an exponential rate so I decided to rebuild the engine that went fine but when I put the engine in and went to back it out of the garage transmission would not go into gear I知 getting two codes a 4f81 and 4f84. I have ordered a fluid and filter and seals which I have not installed yet. I put it on the lift yesterday and noticed kind of a rattling noise coming from the torque converter area. With car running I attempted to check the transmission fluid and gushed from the hole so to me it acts as if the front pump is not pumping fluid correctly. Does this sound typical of a sleeve and seal problem with the Mechatronics unit or do you believe I have bigger issues? I hate to just do a service and that not fix the issue. transmission was shifting fine before I put the engine in I知 really stumped here.

    Any insight would be greatly appreciated, I am a mechanic it new to the BMW world!
