What will make a 4l60e tranny hold 400hp?

yep, i wanted my TM fully removed, but my tuned still left some on it, and the right rpm and range. I did some really abusive driving, and the PCM cut the power, and got back into almost immediately. No where near as bad a stock. But it was prob enuff to spare the tranny. Just got my built trans and coolers, and going to have the truck retuned again.

My opinion, I got 160k out of my stock 60 through a lot of abusive driving. My rearend gave out before my tranny if that tells you anything. I would say keep that 80 in the distance, but not too far away that when that 60 goes out you're down hard on a truck.

I run my 60e in my truck pretty hard, but i have done several internal mods to make it hold up. A 80e is stronger, but I like the fact that the 60e is a bit lighter.
I had both in my shop,
4l60e 136lbs
4l80e 182lbs
also the 80e converter is a bit heavier then the 60e, I think 5-10lbs, but i didn't have both to weigh them.

...the 1st one that blew tore up the drive shaft AND my tranny, so spend the cash on the rear end first and at least upgrade the r&p and at best switch to 14Bolt...

It will handle 400 in stock form for a while and even the rebuild suggested. Look at my sig and im still on a stock 60e with regular fluid changes. I have taken 2 f-bodies into the 10s on stock 60e's as well. If you are careful and mindful of what it can and cant do it will hold for a while. No..its not as strong as an 80e but gets bashed way too much by people who destroy things.
Ill agree totally and respect everyones opinions and experiences....but like one person mentioned above, most people who break them(some even on stock trucks) drive them like they stole it.... 80e is great insurance but I think these folks who go through 3,4,5 trannys and a few built ones need to look in the mirror...there is the problem!....not always the trans lol. These folks could tear up an anvil with a bag of marshmallows! The 60e is not a bad trans, it just has its limits like anything else, be mindful of them and it can live a while.
Having a 65E go 10's in an AWD 5500lb truck is proof they can hold IMHO. Others will disagree of course.

I agree with the above on WOT kick downs kills a 60
I had 108,142 miles on my grey truck and treated like an old man and lost my tranny
I would kick it down ever once in awhile with out manual shift and hauled some BIG loads and these two combined apparently killed it
On the other hand I have friend who leaves his accelerator in the floor and he got 240,xxx miles out of his!
IMO it'll hold it just depends on how u drive it
