When clutch is pressed like red light or traffic. When you go to shift to 1st or any other gear , shifter locks to where cant shift out of any gears. And at same time clutch is pushed in and car revs high and when brake is released car wants to take off. But clutch is in. Then cant shift. But when you shut car off then restart it , can shift out of gears and will be normal but stiff in shifting. When in the problem the car also revs like gas pedal is being pressed but isnt . Very scary almost caused several accidents.
