Can someone offer any pointers on tuning a 4l80e, as far as must do's or essential tweaks that 4l80e's need. Specifically when using an aftermarket stall converter? My trans tune is stock for the most part, I previously had a 4l60e and recently did the 4l80e swap, segment and repinned etc. I installed a Transgo HD2 kit in it as well. Want good firm chirping shifts/lockup and avoid TCC lockup at WOT areas (Per Circle-D torque converter guys). (Disregard the engine side of the tune file, way outdated)
