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.

just drove the ss tonight with the 4l80e and precision convertor, drives and shifts sweet. should have a few pics tomorrow and hopefully find out why the speed sensor isnt working.
Im trying to decide right now weather to use the TH400 again or use the 4L80E for a new project hopefully starting next week. What has the total cost been for you guys?
Trans w/ brake, converter x-member, etc...
Thanks in advance

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
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

stock gears...lost no time anywhere. I use the stock console and shifter (a4)...got the tbrake on my cruis control "set" button...i think it is...the one on the end you push in
could you guys update the cross member part?
i have my m6 cross member, wondering if that is a direct fit (like on turbo 400's)
also since mine is m6 i will have to do all of the cooler line plumbing. what should i do for this? buy somebodys 4l60 lines?
thanks

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.
