Default Transgo 4L80e-3 Data

I've done some searching but I haven't seen any recent treads concerning updates to this kit, or how well it works.
Unfortunately for me, I already have the kit and the 4L80e. Any information could definitely sway my rebuild tactics... Or just scare me back to a T56 Magnum. haha.

So far what I've read shows there are consistent issues with WOT shifting and a delayed 2-3 shift.

Does anyone have updates on this kit? Specifically what changes have been made to the kit or install tweaks that could fix these issues.

Has anyone installed this kit recently? What stall are you using? What hole sizes did you use in the separator plate for shift stiffness?

Thanks for any input!

Is this really such a black hole area of knowledge in this community?

From the overwhelming data I've received from all these posts am I making the correct guess I should just not use this kit in a rebuild?
