Who replaced it? It should still be under the new parts warranty if done by a Ford Dealer.

What motor and are you using a tuner?

I see a 4R75W or 4R75E for 2WD and 4WD

I understand that 2007 was a bad year for trannys from Ford. Had it read, at 60 and above the OD/Clutch won't lock in for lack of a better term. I have 2 other Ford trucks and have had 2 others, this one has been the only issue. I'll figure it out.

I had one transmission replaced in my 07 and my dad had two in his 08, so there might have been something from the factory also.
