Maybe I just didn't use the correct search terminology. I used "maximium hp transmission" and "max hp tranny"
But thank you though man,

with those mods and a good tranny cooler around 350-375 depending on your takeoffs..
the clutch packs are real soft in these trannies hence the smooth like silk shifting.. valve body upgrade alters line pressure for harder shifting which actually increases wear on clutch packs.. the only way is to have tranny built

I am hoping for a good bit more than 350 so I guess I may not have a tranny for too much longer!!

When the tranny shifts all buttery smooth its cause the clutch packs are slipping which eats them away over time.With the added line pressure it slips less and in tire terms "hooks and goes"
Just like a tire that isnt burnt out at every stop light will last longer than one that is.
Trust me I've been through plenty of trannies and been friends with some amazing tranny guys over the years.
A shift kit and GOOD tranny cooler are the best things you can do for a trannies life expectency.
IMHO opinion here is the best cooler around. http://www.derale.com/img/13700remotecooler.jpg
And you might want to add a filter for it too. http://www.bulkpart.com/Merchant2/me...roduct_Count=1

They dont just always pop and stop working. I think more often than not, the result is significanlty reduced life.
If I had to guess I would say much more than 400hp at the wheels you are tempting fate.
Other things also need to be factored in, do you do burnouts, hard launches, is there a tranny cooler, how many miles is on the tranny etc.

I honestly cant say. I havent been inside one of these trannies yet.
And like Morris said it probably wont just "break" it MIGHT but more than likely you will start to see more and more slipping in a particular gear untill that gear is just gone completely and when it starts slipping the debris gets inside other parts and causes more and more damage to the whole unit.
Which is why i suggested the auxilary filter.

But If it were me and I was expecting to exceed 400RWHP than I would have a back up plan in place.Wether it be the needed funds to have it rebuilt or an extra one from a wrecked car.

correct but the added pressure or friction to the plates wear them faster and this i know for looking at the internals of one fried from constant abuse with vlave body upgrade and 2800 trq convt
the packs were toast

Once the plates "stick" to each other for a lack of a better word they are no longer being deteriorated.The deterioration comes from slipping.
