Apologies for any dumb questions, I am totally new to tuning. I bought a 2004 Colorado rcsb that was gen4 5.3 swapped with an earlier 4l60e without ISS. In town cruising seems totally fine, a little bit harsh on the 1-2 but that all, and interstate speed cruising is also fine but when I use cruise control on interstate for 15 minutes or more and take an exit, complete stop or not, my shift mode is locked in "??WOT" and I can't figure out why for the life of me. I have no idea who previously tuned it so no contact there but I've searched for hours and cannot find an answer. TPS reads good and several other PIDS I have watched also checked out good besides torque management. I reactivated TM from the original tune that is linked and it would read 12 lbft at idle and as soon as I'd touch the throttle immediately drop to 0 and I'd have no throttle and sound like fuel cut. TIA
