Would like another set of eyes on my calibrations

[Naf]

I have a 2010 Tahoe, which i tow with, i massaged the trans tune a little, and she feels better, but i have a small problem between 2 and third shifts. Its gets up to the shift point, releases 2nd, but before 3rd has a chance to engage the rpm climbs then it shifts into 3rd and i go about my other shifts...

Cold, hot, low torque, high torque it does the same thing...

Lookin forward to all your inputs

Which pattern is being used...?

Which pattern is being used...?

Either normal or pattern B, i really dont know, thats why they are the same...

I realize this is 2 years old but did you ever reconcile this? I am having the same issues but add in 1-2 as well. Mine is a 2011 Tahoe rebuilt motor and 3000 Stall. Also attached is the motor tune.

So i was told to rise the min spark, my gear shift issue was happening between 3000-4000rpm, i lowered the min spark and it seems to have cured my ghost issue where in between shifts the rpm climbs then engages.

I worked it where everything below 4000rpm has -5 as the lowest, and everything above 4000rpm i have it as -10 instead of -25.

let me know if this also cures your problem

Naf, thanks for the response!!! I will check on this also. Mine is a little different scenario but checking everything helps. I will follow up when I get this figured out.
