thanks for the link but it does not give a reason why. I have a Tech II so I know the code.
You need to send your file to ken if you have HPtuners. He will send it back. He does something we can't.
I am running a 4.10 gear. 1st gear is so long you will need it.

how much heavier is the 4l80 e over the 4l60 e? Does it have to be built or can it handle 800 hp stock?
I ask this cause me and someone else are thinking about this in the future. I may send my tranny over to rock on just like you did, i just dont want to pay 2200 bucks, i think that's too much $$

2200.00 is about right and if you really want a tougher 4 speed auto, its the same as buying a real turbo kit and not wasting your money on a turbonator, brotha!!
I was just in the same boat where i didnt't feel that i had to drop over 2k on a trans when i can get a th400 for under/at 1k to handle just as much power. But a gear vendor is cool but kind bulky the way it feels; so my only choice was a 4l80e since the 4l60e is by far, the biggest piece of crap, transmission i have ever had the pleasure to deal with!!! No WOT into 4th, goes under stock power, good gear ratio's but even with a fully built trans, it'll go with me handcranking the motor over!!
(Sigh!)

It needs to be built to handle 800HP. I have the Hughes Street/Strip 80E and love it. They said in a CHP article that it would handle 1000HP without any problem. I'm pumping 740HP through it now with no issues.

This looks like a great thread.
What wiring harness's would I need to get to go from M6 -> 4L80-E? I'm guessing the stock one plus the additonal one. Part numbers please if you gott'm![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
Would I be okay with the M6 console? I've seen pics with the M6 console and a TH400 shifter, but I don't think they had a Trans Brake and I do plan on having one. What would be a good shifter to get if I was to keep the M6 console and have a transbrake? Pics??
Do you guys have the gears changed in the 4L80-E? The 4L60-E has a much more agressive first gear.
Stock 4L60-E
1: 3.06
2: 1.63
3: 1.00
4: 2.29 (edit: 0.696)
Stock 4L80-E
1: 2.48
2: 1.48
3: 1.00
4: .075

I use stock 4L60 lines that have been tweaked a little (bent out a little to work). I have seen people get braided lines and that is nice too. Its really up to you.

And BTW, I used black Goodyear tranny hose for the cooler.
