'07 BMW 328xi 6 speed automatic will not shift.
The automatic ZF 6 speed automatic will not shift. The warning 'symbol' trans . problems came on along with "CHECK ENGINE SOON". I cannot do much with this problem due to the location of the fill plug. Up to this point, there had been no problems, I had been shifting it in the manual mode at times.
Since the trans light is on, and CEL, the car is in limp mode. I would take the car into your local BMW garage and have them pull the engine and trans codes to let you know if it's the transmission itself or a sensor/solenoid issue. Changing the fluid at this point won't help you any. Good Luck!
Definitely do what Tom said, but 1- what is the mileage and 2- when was the last time your transmission fluid was replaced?
