Cool deal man! Glad it worked out for ya.



So while we are talking about years, what all year 4L80Es will bolt up to a LSx block??

I was under the impression you had to get one out of a NBS 2500hd .???

great deal man


how do stock 80e's compare to built 60e's for reliability behind decent power?

Im using an 80e out of a 98 Van.

Do you think it will hold up to my power and weight without even a shift kit? I am expecting about 500rwhp and my Tahoe weighs 5500lb.

Thanks ! I do not know what all years will work, but I think its a whole lot of them. I know a guy with a 97 one in a 04 silverado, that is the only reason I knew i would be fine with one from a 97.

Theres lots of people on here that just have shift kits in their stock 80e's and they are holding 700-800 hp. Most built 60e's are just a ticking bomb at that hp level.

Another question I have been trying to figure out is. Everyone modifies their cross member to move the trans mount about 6 inches back. But has anyone tried getting a cross member out of truck that already came with the 4l80. And will it work in a rcsb?

Go thru it now... Save yourself the headache and the towing bill later on down the road, I understand the budget but why chance it with that much weight and power?

a buddy of mine got a 4l80 out of a 2000 model 2500 4wd the other day.he also got it cheap.it has about 150k on it.we got to convert it to 2wd so we gone rebuild it but everthing in the trans,clutches and bands look real good.if yours looks good inside when you put shift kit in,i would try it

^^^this

but at the same time, part of me says go ahead & rebuild it because if you don't, it's gonna take a crap at the worst possible time.

BTW, if you find any more of these jewels, throw us dogs a bone & post up a link.

Are you ditching 4wd? because that trans looks to be 2wd.
