I know for years the 4L80 swap has been the way to go. However it seems to me at least that in the last lets say 5 years the 4L60E's have coma along way with the parts available and kind taking the need for a 4L80 swap only necessary for the nearly 900-1000rwhp mark. Would you guys who've installed built 4L60E's in the last few years agree? What horsepower and who's 4L60E transmission are you running with or without success?

You'll likely get linked to a couple threads in here where guys have had bad luck. I can think of a "transbuilderguy" thread that went south a while back.

I build lots of high HP 4l60e's and here's what I recommend to anyone that's going to buy a trans from me. And I'm not the only one...Multiple companies are offering (and honoring) a warranty for that power level in a 60e.

for a camaro/gto or something similar, 600hp is very doable.
at 600hp in a truck is usually where I like to ask the customer to explore the cost/benefit of the 60e vs 80e.

IMO with the right gear and a proper build, 600 can (and has) been done in a truck for LESS MONEY than the cost of a properly built 80e and all the associated swap components.

There has been ALOT of development in the last 8 years for the 60e. And In the next 18 months...expect the 60e to be a contender for an EASY 750 hp. The weak points will undoubtedly be the shafts and hard parts, not the clutches. New valve bodies are going to change the game

MaroonMonsterLS thank you for giving your opinion on the topic. you've spiked my curiosity on the new parts about to come out for the 4L60. Do you have any more info on the new valve bodies?

Maroon kinda started it with car vs truck.

In a car a 60e can live for years. In a truck, not so much.

I dropped the coin on a reputable vendors level 7 and it still broke after 15 months.

I’ve had my 80e for over a year with no issues.

What are your goals with this truck? Do you plan to just have a mean burnout machine that sounds badass rolling into the local pep boys car meet?

Or are you planning to take this thing to the strip and regularly beat on it hard?

and is it 2wd or 4wd?

Unless you have some ethical predilection to stick with a 60e, you'll save a lot of coin, heartache, ***-pain, and time going with the 80e swap. Its not that difficult or expensive and you'll have piece of mind for years to come. Even a stock 80e on a fresh rebuild can handle 600hp in these trucks without missing a beat. I tore up 3 4L60eS before I learned my lesson. Could have done the swap for 1/4 of what the builds on those three turds cost me.

What makes you say this?

I build 60's and 80's for customers...and for 500 hp, the 60e is ALWAYS cheaper than the combined cost of a rebuilt 80e with associated swap parts.
If you want to do a junkyard 80e with a used torque converter...then so be it...but I bet the cost is close to the cost of a built 60e.
