2011 Chevrolet silverado 5.3 Idle acting up weird in drive, no codes stored, Torque converter issue?

Engine has been previously repaired by changing all the engine reactivation lifters, new transmission fluid, new cv axles and all these repairs were done by the dealership and they still couldn't figure out the issue.

Had the same problem with a truck in my shop a 2009 gmc 1500 it would not rev in gear had to hold the brake at idle no codes in trans or pcm shifted no problem in trans ending up pulling the trans found a bad converter the one way startor bearing went bad . Flushed trans and installed a new converter problem solved
