I was wondering if anybody here done a fully built 6L80E with a high stall, I'm going to be putting 600+hp to the ground and I want a 3K stall but I don't think my stock tranny can handle that any info would help thanks

 

I know circle d makes upgrades for the 6l80e but they are expensive!!
Like buying two built 4l80e's expensive.

 

thanks, ima have to email them, any idea how much?????

 

Thy have a spot on their website to send inquires, they sent me a quote but it's been erased and I don't remember. Just make sure to call the transmission shop and not the converter shop!

 

i thought these trannys were already tough enough for 600hp.....

 

thanks man

 

yes but im sure with a 3K stall and launching in high boost it wouldnt last me a month or even a few runs

 

i believe gm rates them for 400rwhp

 

Skipperdaddy is running 520+RWHP and his 6L80E is lasting, Im sure he doesn't beat the **** out of it all the time, but the occasional pull/Launch shouldn't kill it.

 

From what I have read is that they are stout transmissions while in gear, but where they fail is all the parts used while changing gears, 1-2 2-3 3-4 shifts
