This happened to me also. Mine had been stripped by previous owner, so I removed it and unknowingly moved the shifter. Result: The slotted shifter rod inside moved and I was unable to get it back into place. Unfortunately it cost me 350.00 for a BMW specialist to open up transmission and put it back in place and rethread the stripped out hole. It was perfectly sealed before but now that it had been opened up and resealed even with NEW gaskets it weeps tranny fluid. I was warned this would happen by the specialist before he opened up. Long story short your likely going to have to open up transmission to correct the problem. Good luck, My mistake I misread your post. Hopefully you'll resolve your problem without any cost.
