Tranny problem,95 7.3 f-350 4x4
 

It worked fine this morning on the way to work then this afternoon it wouldnt go into reverse and after revving it it did as if I dumped the clutch. It then felt as if it wouldnt go into OD and shifts from 1-2,2-3 really quickly and acts like a lugging 5spd. Trans is not slipping and if anything feels more locked up than before when working "properly".
Is my converter shot??
Trans fluid smells good and it is full also.
Truck has 235K but trans was rebuilt at 165K.

Any ideas??
Thanks guys.
