What needs to be done to a 4l60e that will hold 800hp?
Start at the Stickies in the transmission section here, there are lots of builds of 4l60e/4l65e here... after reading many, many pages, you'll see what's common in them all and take notes, because they hate hearing questions that have already been asked. The Search feature is your friend... though you may never find what you're looking for if you don't word your search properly... or you may find it in an old thread and asking things in old threads is discouraged. Otherwise, there are some brilliant minds here!
Hope this helps.

Talk to Dana @ Probuilt Automatics. He can be hard to get ahold of sometimes but he sells complete kits with all the updates and tailored to your needs. He does custom Transgo shift kits and can set the shifts up for your power level.
