it drives in drive but if you baby it when it shifts out of second it just seems as if it goes in to nuetral but if you gas it and make it wait till 35-40 to shift then it shifts it seems as if it is electrical problems sometimes and then it seems mechanical and if you make it slip when it trys to go into third then you have to put it back in park before it will go to third again
