Can the 4L60E transmission handle 400hp?

Well do you guys think that the 4L60E transmission can handle 400hp stock because on machperformance.com they have a S/C kit that claims to make 400hp and the guarranty it w/out a transmission rebuild, just wondering if yall thought it was possible

vettes have a 4L60E in them, A4 vettes anyway (C5 not C6).

A better ? is will the rear end handel it. Ive had 2 go while under warentee, Mine has few mods.

well if im running a 75 shot of nitrous and have intake, pullies, and ignition do you think that the rear end will hold up...

If you blow it go find an 8.5 inch and try again.

I got some doubt the transmission may handle it.

A transmission manufactured to handle about 200HP will difficulty handle the double in my opinion. Or in the best case if it handles it, it would not be for a long time, that's for sure, it woulnd't last long!

I had an 88 full size that pushed 470HP on a 4L60. Had no trouble till a shop didn't put the trans filter on good. It fell off an roasted the trans.

ouch!

so you can vouch for them being a sturdy transmission....

Most would prefer the 350tH but I have seen a lot put in front of a 4L60 and have seen little trouble at all. Can't say none though. I know that over 600HP will [WILL] make the output shaft look like a pencil. I will be using the a4L60 for most anything as I like the overdrive. I use a bit of fuel so when I get on the highway and my RPMs fall to the floor it makes my pocket feel better. Anyway I say it will to an extent. You may have trouble with the rear gearing. If there is to much of a bite at the tires you may blow the tail on the trans so add a carrier or driveshaft ring just in case.
