i have a buddy with an 07 2500hd with 150hp tune and finally got the stock allison. need some help finding a reliable builder r reman lookin to go to a 250hp tune and more need a wicked tranny

 

Have heard about ats and suncoast. Im sure there are some others out there though. Haven't really researched to see whats what though.

 

ATS and Suncoast would be your bet down in the states for a built up allison... it isnt exactly an area that you are going to want to try and go cheap on eighter

 

thanks for the help guys found a highly recomened place in lake charles calvins transmissions found several people using there transmissions holding some pretty wicked power. not sure of any numbers but plenty of guys from lake charles makin some very fast passes on these trans.
calvins transmissions 337-625-3968
