    750 Li Gear Shift Blinking on "D"???

    Hey this is my first time posting on here and hoping like hell someone can give me some advice. I was recently driving my 09' 750 li when an error came onto the screen saying "transmission malfunction" then "drivetrain malfunction". I was able to make it home (about 2 miles), although the car wouldnt change gears while driving, but when i pulled in the driveway it wouldnt go into park, reverse, neutral, nothing. It just stayed blinking on D. Hoping someone may have experienced something similiar and can help me out here.

    First you need the bme fault codes and If you can't work on the car tow it to a good bmw independent shop. It is stuck in 3rd gear because it is in fail safe mode

    Correct. Without fault codes, anything is just a guess.

    Hope you’re taking it to a BMW specialist and not “Joe Blow Auto Repair”. Same goes for Midas, Pep Boys, etc. LOL

    So i just spoke back with the shop their saying 2300 best scenario which would be dropn pan and being able to rebuild something regarding the selinoid 5000 worst case scenario and that would be replacing something that begins with a m megatronix or something like that. The code is 400126 anyone familiar with that at all??
