Okay so my tranny shifts into reverse neutral and 1st... but not drive and overdrive wat could the problem b?? there are a few things not hooked up but i have no idea weree they go.. the first is a plug that comes out rite near the fuel injectors on the drivers side of the motor.. the second comes from underneath the car and looks like a little electrical piece its real small it looks like half a cig but a plug.. i think its not shiftn cause theres no compression.. Please hlp me
