Is your tranny is miss-shifting into different gears and slipping into neutral and back in gear ? "slam-shifting" If so you need a new tranny range sensor switch $25.oo at ford parts . It is mounted on top outside of tranny . Close to battery and if you remove the battery it is easier to replace part. The new part is now plastic and has 3 bolts holding it on.A half hour job to fix. Also try a can of tranny sealer and conditioner in you fluid ... Yes this stuff works.
