The problem with trying to use the 6l80 is the controller, I haven't seen one successfully installed yet,
Randy said:Sounds like a good plan..
I would love a 6L80, I wish they weren't so expen$ive and I don't think there's a simple coversion for mine, yet..
jpsteele25 said:That is the downside..but building any transmission isn't cheap. Heck my Built 4l60e in my AVA cost close to 5 grand.

Yeah I don't want to Jack this thread but a 6 speed behind a 8.1 will not last and you can not add the 6 speed to a 08 down AV.

A lot of guys with the 6L80Es are swapping them out for the more stout built 4L80Es. It seems even the built 6Ls just don't hold up to the power.
The only thing you would gain is a slight increase in mileage when locked up in OD. But even that is slight, at best.
09chevyavy said:But still, I like the 6 speed. And the ones that transmission center are producing, at a cost of about 7k can hold 1,100 hp... thats pretty stout I must say.
Here is the one I want for just over 5.5k
Zef_66 said:But a built 4L80E will hold the same power for less than half the cost.
09chevyavy said:But what about my gas mileage, and also wouldnt I need to get a lower gear ratio than just my 3.08s? They would stink with a 4 speed
Zef_66 said:Are you interested in fuel mileage or making power to the pavement/dirt? With the mods and upgrades you have planned and the towing/off-roading you do, I figured you would be interested in getting power to the wheels and having it be reliable.
I mean, you've already lifted your truck and put on larger tires, both of which lower mileage. If you are interested in fuel mileage, then spending $5500 on a transmission that is going to save you maybe 1 mpg isn't very cost effective.
09chevyavy said:No, MPG is not the highest thing one my priority list and I do want performance goals to be met and such. But with those two overdrive gears I am currently able to still get 17 on the highway and 12 in the city. Thats not too great hahaha. Im just saying it seems like having those gears not there would bring me down to about 7 and 12 ya know? Especially with my 3.08 rear gears right now
