    Default Would like another set of eyes on my calibrations

    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

    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.
