I have a tuned and deleted 13 and previously had a 12 F350. I absolutely HATE the way my trucks shifts. I've ask a few people with the same trucks and they say no issues. Am I the only person that hates all of the shift flares, harsh downshifts, and just general crappy shifting? I've got a box stock Mini maxx and I've even tried Innovatives files in an SCT. Still not to my liking. My question would be has anyone else had any issues with their trannies? I don't think it is mechanical though, pretty sure tuning may fix it. Thoughts from those of you with MCC files and who did you use? Power levels suit me fine, just hate the shifting. And at times when going from forward to reverse trying to get in a parking spot I put it in reverse and there is nothing there. Have to shut the truck off and restart and everything is fine. Help please

Im running Gearhead in mine with H&S mini, I still experience flare at low rpm between shifts. Past 2k rpm everything is spot on. Way better than h&s Trans tune but not 100% like stock.

:whs:
The harder I push mine, the worse it shifts. The opposite is true as well. Gearhead shifts night and day better and has more power as well.
So, I guess I'm not the only one that hates these transmissions? When the truck was stock I thought the trans was the stuff, tuned not so much. I just hate to keep throwing money at it with the MCC unlock and more tunes. Thinking maybe selling and going back to a 6.0 or 6.4, hate it because I really like all the creature comforts. Thanks for the replies

I don't know what to say. I have the factory H&S files and three different gearhead trans files and still have harsh shifting and shift flares. The Power is awesome with Gearhead!
Haha, on the way to work this morning I was almost out ran by an 03 6.0 with the Mini on high! Everyday I'm less and less impressed by this awesome 6.7. I guess I just expect a little more than what I'm getting. And I do have all the cool stuff from Mike, I'm just thinking out loud here. I honestly think a well tuned 6.0 or a 6.4 would spank a 6.7's azz.

a six oh would be close and a six four will spank it.

Yep same here wasn't all that close a tuned 15 vs a tuned 6.4. The 6.4 walked away.
For real? What does a tuned 6 4 push? 570? I've heard the 2015 6.7s push 550.

I ran against a tuned 6.4 in the 1/4. He ran a 13.29 and my fastest pass was 13.59. It was very close and I was pretty pleased with my truck. He had built trans, intake and running his hottest tune. And he had traction bars and could launch much harder. Mine just would wheel hop. I feel like if I had traction bars and a built trans I would have not had an issue beating him.

Multiple guys have seen 540-550 on a top tune for a 2015 6.7...
That what I'm saying. He must be racing crappy tuned 6.7s
