One problem related to transmission not go into gear has been reported for the 1997 Ford Ranger. The most recently reported issues are listed below.
This truck accerlerates by itself, it used to only be between 2nd and 3rd gears but now I can be on the freeway and in 4th gear when I can feel the pedal go down to the floor, I'm forced to put it in nuetral until the rpms go down, trying to get it into another gear only grinds because its running too high. This is a safety issue, if it happens at the wrong time someone could get hurt or the engine will just blow up!.
