2014 5.3 chevy

Ah ok. Well I set it back to +15 and it may have a ever so slightly bump to the sift from 1st to 2nd but I only did 1 pull. I'll play with it bit if it's still doing it and back it up to 12 or even 10.....I finally in love again with my truck especially with having the extra juice for the small increase in tire size. Thanks a ton for fixing it. Let's just see if I can keep my foot out of it now cause it'll roast these 33s till traction control kicks on if I let it lol.

Since it seems like maybe this got fixed is this going to be a new program that will be uploaded such that if I update my tuner I will be able to get the same program? Or it's just a custom tune for that individual? By the way thank you very much for your time and effort.

Hi

Put me on the list for this TCM update my truck bangs pretty hard shifting at WOT.

Did this fix ever get updated in the canned tunes? Mine bangs at WOT too.

I can fix in a custom tune for now if needed, post up the tunes from your tunes folder on the tool please.

Thanks

I posted this in the other tread about shifting issues. any ideas?

I have a 2014 Sierra all terrain 5.3. I'm having the same issues with the 1-2 shift being hard even at light throttle. I experience the bogging issues a lot when I get on highways. Giving more throttle causes a downshift that seems to skip a gear. And at full throttle the shift is so violent I'm afraid somethings is going to break. I have tried several different tunes and adjustments all with the same results.

Attached are my files. I'm using the canned 91/flex with only tire size and speed limit changes and the hard shift tcm tune with no changes. I notice I get the hard cluck shift at WOT, part throttle shifts are just fine.

Thanks,
