6L80/6L90 transmission build?

[JoshH]

Does anyone know if there is a company that is doing anything with these transmissions? They are used in the Camaro and CTS-V. I did some searching on Google but couldn't really find anything.

I think there are a few things out for them. I recall finding some stuff for them on patc's site.

I think I have one in my gas truck also. She has a ton of miles and needs a refresh.

IIRC LoudPedal Racing was doing converters and builds on them for the camaros here in PHX, but I havent researched it much.

Should be a 4L80 in your truck if you're talking about the 06 in your sig.

Circle D is doing some things with the 6L80E/6L90E trans.

I'll 2nd Circle D. They have done quite a bit of reverse engineering on the 6L80 / 6L90's and GM High Tech had an article about a year ago about it. Quite a few guys with late model cars have been running their stuff.
