    jeep jk nag1 conundrum

    Hello, newbie here. Tried search function, read tuning school books. Can not for the life of me figure out how to disable the torque convertor lock up in any gears in my 2012 jeep jk. tune file attached

    Just set the apply speeds to the maximum RPM possible and that should inhibit the TC locking up in that particular gear.
    Looks like you have already done that in the tune but you also maxed out the release speeds. Set the release speed to 0 and that should keep the TC unlocked.

    No luck on zeroing that table. Also attempting to firm up shifts, added a couple psi to the fill tables. Shift is firm in manual mode but the not in drive. Log attached
