i personally have to disagree with this statement. No offense to ben. I tested his boxes in house here at Suncoast. The 6 speeds worked FLAWLESSLY. 5 speeds however... Not so much. After 2 tcm's and limping the test truck home from pensacola (would not clear, locked in 3rd, - degree temps locked out) The ATS box i've had in my truck works perfect. No issues whatsoever. I can't speak for the ally locker, but if it's anything like their new tapshifter i believe it will be a great product
I'm not saying every box that leaves bens shop is perfect there have been issues with harnesses or boxes. Once those issues were resolved I yet to hear of it flat out not working
