upgraded transmission?
I have a 2011 gmc sierra LML and i have put a enclosed cold air intake, MBRP exhaust and a H&S mini max programmer. it is pushing around 500 hp as told by my mechanic and that the stock Allison transmission cant handle that. so what do you guys recommend for a new tranny?

2x - this is where i got mine done
dont know where these HP numbers are coming from, 1000hp, 900hp, 700hp...
it is pretty well known among the pro tuners that the 6 speed Alison will usually handle about 90hp over stock but anything over will shorten its life, some faster then others

Suncoast 6R-3, MLG TC, Goerend PTO covers will get you a butt load of power to the ground. Mke L, Calvins, Big Dipper and many others can do this work.

Ding ding ding! Wow, only guy with a real answer on power ratings for the Allison. However, from what I've seen is that the LML trans is a bit more stout than previous model years and can handle about 550 rwhp without serious modification. A lot of guys out there running about that and still going strong after thousands of miles on high hp tunes. That's not to say a guy can't blow it up going full idiot and doing tug of wars...
