Sometimes car doesn't wanna go into D or R from park and sometimes doesn't wanna go into to P from D.
So in order to bring it back to P i have to turn the car off and open the driver door and close it back and to do that i put the car in N and when i turn off the car and open the door while the car is still in N i hear a little crank noise which seems to put in park and when i turn car back on seems like it resets all the issue.
Cant seems to figure out what could be the issue. Gears shifts and drives normally.
Drives smooth and gear shifts is perfect as well.
Gets really annoying sometimes.
Thanks in Advance![Smilie](https://mbworld.org/forums/images/smilies/smile.gif)

Till is not too late, maybe you can try a professional diagnose. On the left side of the Gearbox, an ISM ( Intelligent Shift Module) may not reset anymore and will be very hard to tow...

Those few people are most likely wrong. Turbine speed sensors result in tranny getting stuck in gear and going into limp mode while moving. Again- this can be confirmed via star/ das.
