I think the conversations surrounding the upgraded 4L80E's may have centered around a company called "JET" ? Not positive... I know that those are the guys I talked to when I was weighing my transmission replacement options a few years ago.

I actually had some lengthy discussions with some transmission experts a few years ago when I replaced mine that made me decide to go with a stock replacement instead - not for financial reasons, but because they convinced me that the standard version was better... some interesting differences in opinions out there about "hardened" gears that are rated for higher HP breaking sooner vs. softer metal that gives a little, etc.
