Can someone please explain why this is in my Galant? It's neat to mess around with but is there any real advantage to using it? All I can tell is that it lessens the traction control. Also, does it hurt the transmission to switch back and forth while the car is moving? If I was to use it from 0-70mph and then switch back to auto, am I going to mess anything up?

 

??????? what are you talking about ??? the front seat ????
