When I accelerate from a stopped position, I have to completely let off the throttle for at least 5 seconds until the engine switches gears. If I continue to accelerate the RPM's go through the roof and it does not change gears.
My 5.0L V8 Explorer has problems switching from 1st to 2nd gear. Whats Wrong? on 1998 Ford Explorer
possibly synchronizers are bad.
