All - I have been trying to read, but haven't come across any good applicable threads for my question.
I have read mixed comments on TCC lock for WOT.
Here is my stock WOT TCC lock "normal" lock. 2018 Sierra 5.3L 8L90E

WOT runs it will lock on me and I am trying to figure out if that is good or bad. From what I see, many say do not lock at WOT. I am wondering why the factory tune allows it. What are the benefits and risks? Ultimately I am looking to see if I should disable.
I get what I feel is a slight shake on hard accel and I have not been able to pinpoint it. I *think* it happens in 2nd, which led me to this question. I am wondering if the TCC lock is causing that sensation. It almost has a slight imbalance feel to something when that happens. I am going to try to tie it to RPM, speed or gear.
