    6l80 help with gear shifting

    Hello everyone, I'm trying to start understanding some things in HP tuners, I'm having some very abrupt changes from 1-2 and especially from 2-3, could someone help me?

    Some very abrupt changes as in a harsh shift?
    The shift pressures are very high in the tune.

    Yes, I compared it to the original, but I wasn't sure if I should change the shift pressure, shift timing, or torque management.

    Shift timing is the important part. The trans will adapt pressure up or down to achieve that time. Torque management also plays into it. This guide covers everything.

    Can you tell me if this tuning is the same as the export Camaro that came to Brazil? I'm not sure if I can use this as the base for the engine and transmission, because I don't have the stock

    I made some changes and it was how I wanted the changes, but 1 to 2 is changing at 5,500 rpm, I've already used the bluecat and everything is correct, I wanted to change at 6,000 rpm, does anyone know what it could be?

    I'm going to post two logs, the first one I walked a little to adapt and then I accelerated, in the second one I walked a lot more and finally I accelerated
