Got my ATk hp24 in April 2012, my daily driver 3sp auto 31s with 355 gears, better fuel miles, have 12,000 miles on it so far no problems. Happy happy with it, when I need to pass someone I leave them sitting still, wished I did this when I got my wrangler. Fun to drive now , I do have a boredout throttle body, borla header, highflow cat. & muffler . Can't say anything negative about it, just glad to have it!
