2006 750i transmission code problem
Today I was leaving my house, put my car in reverse and it throws a transmission code which I didn't write down. I'll put it in reverse it will go to reverse then right back to park. When I put it in drive the exact same thing happens. I put it in drive hit the gas and it seemed to go forward, then put it in reverse and all of a suddne it's working fine now. But when I went to the mall, leaving the mall the exact same thing, put it in reverse and it goes back to park. I tried to see on the Idrive if I had any error codes but I didn't. I was able to put it in drive hit the gas before it goes back to park and it worked and I was able to leave the mall but still having this problem. As far as driving after this the car drives and shifts fine it's just from the beginning while parked that it has this problem. The car had been sitting for four days but I drove it to the gym today, then after I got home from the gym was when all this started happening. Somebody please help it's really frustrating!!
