I have a clean low mile 4L80 core that I am going to have built for my trans am. this will need to take 800-900 hp. Does anyone sell a "kit" with all the parts I would need? Any recommendations? thanks.

The top kit comes with electronics, if you're interested in replacing those. Bottom kit is just soft parts.

Let us know what you go with, and your experience with that kit. I was looking into a DIY rebuild for myself.

 

Anyone read the article in GMHighTech about the valve body kit from transgo? They claimed it was easy to do and upped hp holding ability a lot. It redirects fluid in the VB to put more pressure on the clutches, from what I can tell. I didn't study it too much, well, because I don't have a 4L80E, lol.
