trannie trouble

i have a 03 f250 7.3L auto... the truck has been great to me for 145k miles wit no issues but a couple months ago i had a few occasions where i would put it in reverse and it wouldnt move, tried forward and still nothing, then i put iit in park and back to reverse and it went in gear, that happened a few times.

Well a few days ago i got in it pretty good taking off and it would'nt shift out of first, i let out of it and then it shifted, all other gears worked fine. that happened everytime i got on it so i started easing arounf and it always shifted great when i was being easy.

Last night it started haing the same issue with me being easy on it. now everytime i take off it wont shift out of first until i let out of it.. the rpm will get up to a lil over 3k ant it still will not shift, when i let out of it and the rpms drop it will shift, and really hard too. all other gears shift out as normal.

Has anyone ever experienced this? if anyone can help it would be greatly appreciated and i thank you in advance!

I had a problem similiar to yours. I had the hard shifting, along with my transmission couldn't figure out what gear it needed to be in. So, I took it to a friend of mine that specializes in E40D's and he told me that the tranny was in a limp mode to try to save itself and that was why I was experiencing the unusaual hard shifting, along with the tranny not being able to stay in one gear. The tranny was having to much slip on the clutches, etc, so the tranny was trying to save itself by increasing the line pressure. So, I had my tranny fully built with more clutches, billet parts, better tc, and a far better tranny cooler,etcetera and my problem has never come back. But, all the fancy parts werent necessary, just a good rebuild and new tc would have sufficed, but I have some high horsepower goals. Hope this helps.
