I changed the trans fluid ,and had noticed the 2 wire plug is in need of a new black rubber boot, keeps on falling off, and the passing gear will not engage when the pedal is mashed down, so after some other advice I drove my car and pulled on the electric kick down switch by the gas pedal and the car went into nuetra(l,and not into passing gear) I am wondering if my switch by the gas pedal needs to be replaced,thanks
