Well googled parts for a 6l80e trans and The Transmission Center came up first on the list so checked it out. Supposably they have build kits and a bunch of hop up parts for these transmissions. What cought my eye tho was 3/4 of the way down there page they show a parts list that supposedly will make the 6l80 handle up to 1200 rwhp! All the parts are around 3800 which isn't bad if they really can handle that much hp. Now they don't say what they put it in that handled that much so not expecting too too much but wanted to know if anyone else has seen this? Can only imagine how badass these trans would be if they can really be built to handle the abuse of a high hp and weight of a truck. I'm def in the market for something like this as I am not gonna ditch my 6 speed but really do need something that can handle 1k+hp on a daily bassis.

Yeah thats the place

 

There is no way that trans is going to take that kind of power!

 

That's what I'm saying but that's the rwhp rating they gave it... Just wanted to see if anyone has used or heard of any of there parts?

 

I bet it will take it one time... no guarantees after that tho

 

Fixed it for you.

 

How about that

 

Probably closer to right.

 

If you want a trans to experiment with I'll sell you mine out of 08 2500HD 4x4 . $850 if you figure out shipping . I just sent a 4l80 to houston through frieghtquote to another member from PT.net I can look it up if your interested. it had just over 82,000 on it when wrecked going to pull pan this weekend
