Transmisson Issues

[smiked1]

Hi,

I have a 2015 X1 xDrive35i. Never have had any issues with the car. Transmission has always shifted perfectly. A few days ago my wife pulled out of the driveway. The dash llt up like a christmas tree, shifting was very strange. So she turned around and drove home.

Since she parked the car it will not shift out of park. I use my icarsoft scanner and it cannot communicate with the TCM or CAS. It will shift into gear and drive if I manually override the shift lock. It shifts pretty clunkily into gear, and seems to drive in limp mode. I have only moved the car in and out of the driveway like this. I haven't attempted to drive for fear of damaging the transmission driving without a working TCM.

My first course of action was to replace the battery, since it was pretty old. She also experienced a slow crank issue a few times recently. This had no effect on the situation, and system voltage appears to be sitting at 14.9v. Which appears to be within spec.


I have the following codes:

DME:

3BDD
3BE1
3BD8
CD8F


Transfer case:

CF80

Any clues as to what may be happening here would be greatly appreciated.


Thanks.

Mike
