I have a 1991 Caravan.When I start out in Drive and accelerate to 20-30 mph it jumps out of gear as if in neutral.However if I turn the ignition off and then back on,it reengages into 2nd gear.Also I recently lost the reverse gear completely.Could there a bad sensor or something else causing it to do this?Any help or information would be great.

 

It sounds like it's time for a rebuild or a replacement transmission. Our '89 had the same symptoms and it died shortly thereafter. Take care of it before it leaves you stranded!!! Good luck!!
