Hi, I have CLA 250 2014, 22,000 miles, no warranty due to rebuilt title.


While driving on freeway at 65 MPH, transmission shifted out of Drive. There was no noise, no impact, nothing. I pulled over and shifted back into Drive and car wouldn't move at all even though RPM's go up. Also, I am able to push the car even though it's shifted in drive. However, It shifts and drives into the reverse. No check engine light.


What could cause such an issue? Any help is greatly appreciated.

Thanks!

Oh my ...
Aside from driving around in reverse it sure sounds like a dead transmission control unit
Except no CEL is a new twist this TCU failure usually comes with christmas lights in the gauge cluster

I would take it to a good independent shop, since you have no warranty. I am also shocked there were no lights when this happened. Good luck and please update us.

HI, the code that I am getting from transmission is 06B00 - The torque calculation of the control unit has malfunction. DTC Status: Current. I attached the picture. What is the problem and can you repair this?
