6L80E in a 4th gen?

If you're good with code I think Megasquirt's GPIO could work. It's already CAN bus and completely configurable six ways to Sunday.

Actually...
Mast Motorsports makes a Controller that will control a 6l80
and actually...the 6l80 itself.. physically is extremely simple according to a buddy of mine who works as the Transmission tech at a GM dealership...
the programming that was done for it was mostly done to make it handle more power than it physically should...
I think it could be dumbed down and written quite easily...most of the programming is torque management
engaging a solenoid to change a gear is still the same as it has always been...
I personally opted for the TCI 6x
I did the math, and decided the $$$ difference in a completed swap from a t56.. was minimal.
the performance difference... was noticeable...
I picked up a 0.5 seconds swapping from a t56 to a TCI 6x, a buddy of mine with similar mods, similar HP/TQ curves, and similar t56 track times and mph..my buddy only picked up 0.3 seconds swapping to a 6l80
we are both using a Yank PY3600 converter
0.2 seconds and 4mph difference between the two of us.
we were both a 1.6 60ft
both the same at the 330,
and I was 0.2 ahead in the 1/8th and the also at the 1/4
Should be solid enough proof for anybody who is considering the 6x..

the TCI 6x uses a 4l80 Case....
so it fits just like a 4l80
as with any 4l80, you have to cut off one of the ears on the casing to clear the exhaust, and you need a different driveshaft...no big deal
I had to hammer in a few spots....but nothing too crazy
of course, I did just use an air hammer with a flat tip on it to knock in the spots that needed it instead of manually swinging a hammer..LOL
right where the main Connector is, I had to bash in a spot to make it easier to access it...

a 6L80 and a TCI 6x are two totally different transmissions...
the 6x will handle quite a bit more power and torque than a 6L80, and a TCI 6x is easier to install..
from my personal experience of Tuning Cars with 6l80 transmissions...
its also easier to tune a TCI 6x, and it shifts faster than a 6l80

pardon me for resurrecting a dead thread but does anybody know who makes a bulletproof 6L80? It's been almost 2 years since the last post somebody out there has had to perfect this buy now.
Since we're on this subject, who makes the best torque converter for the 6L80 at this point?

Subscribed, I want to know this also. I've changed directions and plan on selling my Firehawk and getting a C6 Grand Sport A6 pushing at or above 800hp. Got to be somebody out there that has figured this trans out by now..

The transmission isn't the issue. It is the GM controller. There are too many things that dictate line pressure. The 6L80e and 6L90e will never be a viable transmission for high horsepower till someone makes a controller with a static line pressure and extensively simplified operating system.

Hmm. well keep a car about stock height and modify the tranny tunnel, get some custom wiring bits and some good tuning and it could work.....id love to see it....but i couldnt drive it in my area due to clearance issues.
Then again if someone made the car a trackqueen they wouldnt have issues getting it around.
I think we will definatly see someone get it done within the next three years, whether it be here on tech or somewhere else.
