depends, id have to serously look at it and do some research.
untill towing with my 4300, i really dont mind the Alison. But yes they are limited with power.... kinda like an NV4500 really lol
a built 12valve and a 6 or 13speed would be awesome in my truck with an air ride conversion. Id be happy. Chad didnt seem interested in taking the truck for a month when i offered.
