Transmission shifting
I have a 2000 F-250 project truck I bought this year. I have upgraded to 205/30 injectors, stage 2 turbo and have gotten custom tunes from 1023 diesel and JeliBuilt.
My transmission before and after custom tuning upgrades will not shift into 3rd I believe. I never really feel the shift to 3rd at all. It will always stays at high rpms (b/w 2,500 & 3,000), just making the truck so loud all the time. It goes from 0 and stays at the high rpm’s without having the shifting point of making the rpm go down. I don’t know what has been done on transmission by previous owners.
Does anyone have ideas? I live in Atlanta if anybody know any shop that could possibly fix this issue

I would probably start by pulling codes.
The favorite around here is FORScan (cheap app) paired with a BAFX or OBDLink OBD tool. Directions for FORScan can be found in the tech folder sticky at the top of our forum.

I put a diagnostic scanner on there but no codes popped up. What would probably be my best bet now?
