Found a 4l6oe will it work?

Try looking at the vans, the 3/4 service vans for cable and phone companies came with a 4l80e behind the 6L and even the 5.3 in certain cases. If you get a cheap 4wd 4l80e and need to have it rebuilt, you could have the tail section changed over to 2wd style.

a 60e with 650+ hp I'm guessing has to be a Monster or Jake's stage III/IV or similar. Guys with 60e's behind near stock fbodies were grenading them within the first few years when driven "actively". Its not to say that they don't make 60'es that can hold that much....its more the issue that if your gonna drop 4-5k on a built trans, spend the extra $100 and get an 80e. Besides, you don't have to find an 80e that was behind an ls engine, like you would when looking for the 300mm lsx style 60e's. iirc my 80e was from a 97.

Nicely said. I was thinking the exact same thing, for both points.

I had a buddy with a cam/header 5.3 in a silverado blow up a Monster 4L60E. They just DON'T live. I speak from experience....even 4L65Es have no business in a performance vehicle.

My 4L80E...bought it used for $400...put a shift kit in it, and a Yank converter...holds up to my 500 whp C-10...and it gets abused a LOT.

Kwin, you mentioned that you're an older fellow and implied that you won't be driving it like you stole it. If that's the case, it will probably live for you. But if you plan to tow with it at all, or drive it aggressively (WOT 4-2 downshifts, etc) save yourself the headache of doing it twice and pop for the 80E now.

$0.02 from someone who's been there, and done that.

I'm in the same boat. I recently purchased a 5.3 attached to a 4l60. I plan on making big power so it sounds like I may go with a 400t or built 700r after hearing all this. Stupid question? Do the 4l80's have overdrive? I'm pretty sure they do but never owned a vehicle with one.
