Default LB7 Transmission Advice

Hey guys im fairly new at this and havent had a lot of experience with modding my truck. i decided to go big or go home and get the PPE hot 2 programmer and a cold air intake along with a 4 inch exhaust. I have been watching my pyro and even on the 220 horsepower setting it doesn't get much over 1100 degrees my main problem is the 5 speed allison i was wondering what is the best rout to making my truck to be able to handle the power. do i buy a clutch pack and rebuild or go with a different tranny what would you suggest

Suncoast without a doubt if you want to use the power you added. Otherwise turn it down and baby the Ally.

Will a rebuild kit do for the six speed? or are you talking new tranny?

A Suncoast rebuild kit is fine and a new converter. Its a 5 speed not 6 on the pre 06 trucks unless you do a conversion.
