I have a 06 f250 with the 6.0. About 2 months ago I put a new tranny in it built of course. But here recently it's been down shifting hard 1-3. And also some time usually 1-3 it will stutter wile shifting. And once in awile throws it's self in over drive early like around 47 mph.. Is this a solenoid problem? Or should I try to retune my transmission? Thanks

downshifting or upshifting?? With very light throttle it should go in to O/D converter lockup over 45 mph.

Is that when you go to accelerate or coming to a stop it downshifts hard? What gear does it studder? 2-3 or 3-5?

1-3 is an UPshift, not a downshift. I think that's what is confusing.

3-1 when I am coasting to a stop it down shifts hard. And 1-3 wile driving every now and then it's like it gets dead peddle for a couple seconds then goes again. From 2-3 is when it wants to fall on its face the most. But also happens in first and second..

The 2703 is telling you there is an issue with the direct clutch. You may have more than a solenoid issue. Have you removed trans pan to inspect for metal? My trans was getting stuck in third coming to a stop, and sometimes (not very often) had a problem with the 2-3 shift. I replaced 2 solenoids (EPC and INT clutch), removed and took apart valve body and cleaned everything including all the other solenoids. So far, my issues are gone (fingers crossed). Its been about 250 miles.

Buy alot of brake cleaner. You'll need the solenoid body and valve body gasket also. I'd recommend changing the inline and in pan filters also.
