My sig isn't to tell everyone what I run or answer people's questions, it's for me to do what I want with it! 
acethedragon & Joshua, anyone...How are the built trannies takin a dump so fast when the stockers have lasted? All I can figure is we think they'll hold up, so we push them harder. 
Or...power was added, & kept being added that wasn't there on the stock ones.
Cause if stockers hold up better than built, why would 1 upgrade their unit?

Most of the trannies that end up failing that I've been around have been a direct result of tuning rather than putting too much power through them. Just by taking out all the Torque Managment from your tune will make life on your tranny much harder, increased line pressures and shifts will put wear and tear on your tranny too. Improper converter sizes and locking them up during WOT will also shorten the life of them.
Personally, I think the tranny is the LAST place people need to search for quicker times and power. By locking up the converter, getting shifts that will slam in and out of gears and chirp tires at every shift will net us a few tenths here and there but is gonna make your tranny wanna roll over and die that much quicker.
IMO if you wanna go faster, make more power with the motor, don't try to squeeze power out of the already stressed drive-train components.

It's a FLT 4L80e lvl-5 if you really must know! My sig isn't to tell everyone what I run or answer people's questions, it's for me to do what I want with it!

It's not? I beg to differ.

However, I never knew bout the improper convertor could shorten tranny life nor WOT lockup could do it too.
I knew if ya towed w/. too small a convertor it would hurt somethin, but I figured it'd just smoke a convertor. But I suppose, that tranny goes as a result of convertor very quickly after. I choose a stall based on "bulletproofing" my drivetrain, not cause I wanted to tow or wanted killer ETs, & I told Chris that when he recommended my stall. That's me tho.
FWIW, I plan on my power outta the motor by fall.

mine died cause of line pressure and shift kit. shifted nice and hard but wasnt meant to last. stock trannies last so long cause their soft, absorb the impact and horsepower. built trannies are meant to get the power to the ground so its definately harsher environment. just so many variables to consider like others have stated. most important is who built it.

It's very important who built it, it's more important who tunes it. There's a local guy in LA who's a transmissions worst nightmare...he's ridiculous and is responsible for 2 4L60e failures of mine as well as my FLT lvl-5 80e and that was waaaaayyyy before I was making any power. I mean he destroyed a $5K transmission behind basically a 6L with bolt-ons.
