My 5.0L V8 Explorer has problems switching from 1st to 2nd gear. Whats Wrong? on 1998 Ford Explorer

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.
