Overdrive stall issue?
 

I have a 1997 ford f250 7.3L with and E4OD trans. I replaced thetrans about two months ago and havent had any problems out of it til about a week ago. Every so often "when cold" the trans will shift fine until it reaches overdrive, then it feels like i have no power and the tach stays about 2000rpm at 50-55mph. no matter how much throttle i give it it wont go above 2000rpms and the truck will slow down. If i release the throttle and let it down shift then accelerate again it will shift into overdrive. Any clue on what it might be? It doesnt happen everytime i drive it, only about three times this week. This is really bothering me as the trans is new and it has only started this week. any help would be great
