Not shifting right???

I have an 05 f350, the truck shifts from 3-4 funny sometimes, it sorta stalls in between sometimes, sometimes it skips fourth and goes right into 5th gear. I had it reflashed, that didnt change anything, i put a sct chip on and that didnt help either. I put another tranny in and it did the same thing. What is my prob? CPU?

I have had this EXACT sporatic shift flare between 3-4 when running stock or tunes from dfuser. I was once told that's when the converter is locking up.

I would get a custom tune from innovative and you won't have the shift flare anymore! I run ID's standard Street tune as my daily driver and the shifts are tight in each gear. Absolutely no wierd shift flares regardlless of throttle position etc. I found that shift flare extremely annoying!

I have the sct tuned from innovative and usually run the extreme street and it seemed to still do it with the tune in also. So there isnt anything wrong with the cpu???

solenoid's in the transmission valve body can cause this leading to weak, flare, shifts. They can be contaminated by clutch particles and it leads to those issues, or it can just be a weak solenoid its an easy fix. The problem with 03-07 5r110's is they dont really have a filter in the pan but this can be fixed by swapping in an 08-10 pan and filter to help prevent that.

Mine is doing something similar. It will only do it while I'm doing a harder acceleration. If I'm just cruising around I'm fine. It will vary on what it does for example sometimes the truck will try to shift but wont engage and hit the rev limiter and then shift. Or there will just be a long delay between the shift. I think I may need to replace my solenoids because I've tried everything else.

No one was used but the other one i had rebuilt with suncoast parts, i flushed all the lines out and used about a quart of fluid. Its just funny all 3 were doin the same thing. Thats why i was wondering if it was something in the cpu.

that particular solenoid people replace just because it's not the best from the factory and the modified solenoid will firm up that shift and get rid of the flare
