    15 Sierra A8 lock up release question

    I?ve got a 15 Sierra 6.2 A8 I?m about to tune. I hate how when shifting it does V4 lock up shift, V4 lock up, shift. I want to disable the lock up in 1-6 gears but I noticed in the tune the converter locks up at WOT. I?m used to gen 3 stuff that never locks at wide open. If I disable the lock up at part throttle should I leave the WOT lock up alone or leave it unlocked all the way through in 1-6. This gen v stuff sucks all together.

    The lockup for shifts are in the trans settings. You can set it for each gear

    But do I need to disable the WOT lock up or leave it stock. I just don?t want to destroy the transmission.
