Hard shifting after transmission tuning

Hey guys, I have 200 miles on my truck after deleting and tuning with trans tuning. 2nd into 3rd shifts pretty hard and 3rd to 4th can also be pretty stiff. How common is this and will it eventually calm down some? I'm worried i should already begin looking for somebody to rebuild my trans.

Did you do the proper drive learn procedure? Staying under 30% throttle for the first 50 miles in stop and go traffic. Preferably shifting as much as possible 1-4 and eventually getting to 5th and 6th.

It sometimes takes 300-800 miles for it to settle down completely but it should be pretty decent after 200. Are you running locked or unlocked shifts? Have you contacted your tuner?

If you did the relearn, you may be running locked shifts. Those can be pretty hard the first time you go through them.
Try reloading the tune and going through the relearn again. These systems are not the brightest and sometimes need the tunes to be loaded more than once to take correctly. If you can, watch the trans cvi values. When they stop jumping around you will have prettyuch completed the relearn.

So it doesn't jump into gear all the time, but most of the time. If i continue to accelerate through 2nd and into third it shifts hard about half the time. I'm not sure if im able to have the tuning done again without paying for it and don't want to spend more on it

If you have another tuned truck to compare, you might find that your shifts are what a performance tuned shift point feels like. Mine does 4-6 in lockup and I like the firmness. The transmission likes it too. The lower gears might shift unlocked depending on load vs tps.
My 68RFe feels like an Allison big truck auto. Exactly like it.
I'm running Anarchy with CSP in 2 (tow).
Still, what suits is subjective.

My wifes 16 had a hard shift from 3-4 not firm but hard. Went back with stock trans tuning and it shifts good now. It was hard enough that on the shift it almost sounded like a turbo bark of sorts but it was from the trans. Also i had about 2000 miles on it.

I don't know what tune you are running but when I had the EZlynk 50hp tow tune and trans tune installed in my truck the transmission shift went from smooth to smoother. Maybe I just got lucky.

Who was your tuner? It was likely locked shifts that made it "chirp" or "squawk" on the 3-4 shift. They should be able to send you a revision with unlocked shifts, even if it's just for the 3-4 shift.

I had a local shop do it from CTT. The its really just the 2nd to 3rd shift that is bothering me now and 3rd is a locked gear. What's happening is that around 1600 rpm the rpm actually drops slightly, like it was going to shift before trans tuning, but it can't shift there any more so the rpm comes up then shifts and causes it to shift hard. So if that won't fix with a couple hundred more miles and more shifts then I will need to contact my shop???

Thanks for the responses and help guys...

They did send a revision with unlocked shifts. Also informed me that they did thousands before me and no complaints. Maybe my truck was different or maybe i messed up on relearn but either way it wasnt right in my opinion. But like i stated they did fix it so all is well now.
