When you come to a stop (like at a traffic light or to turn) does the transmission downshift? Are you going into 4th gear? My transmission didn't want to downshift when there was a VSS fault. Not sure if that's what your issue is exactly, though.

Sounds like a problem with the program /tune. Did you do it yourself? I think there are tables that control this.

I also assume you meant reprogram when you said " tune". If not I apologize.
