My car has problems with Velocid changes

Ok According to you at 20, then it brakes and sets reverse if it shakes the whole car and when putting the drive you do the same your box is blocked. Turn off and turn it on, you have the same operation if it applies softly in reverse and drive then you will have to scan to check if your computer the transmission solenoid package or if the entire transmission is damaged.

Thank you for your comments, but my car is standard.
