Coming up with a list of recommended performance parts / changes to make on a 4L80E build. So far I have come up with the following:

Transgo shift kit
Level 10 transmission rebuild kit
Rossler trans brake (not compatible with transgo)

please add more parts to the list,
Thanks in advance,

 

I'd through in some vaccuum modulated valve bodies for nice shifts in town and firm shifts at WOT. It'd be nice to have the TCI standalone computer too, to much for me right now, but I'll go that way eventually.

 

Im curious about this too.

So far all i have gotten for mine is:
Transgo HP-3 Full manual kit.
TCI 4l80 trans kit
Kevlar Bands
