It works :thumb: I have ran Braydens box(not good), manual lockup switch(didn't work), CoPilot(didn't work)... Bens box the second you press that little button during a WOT 1/4 mile pass INSTANT lockup feels like a 40hp shot of nitrous. If you want lockup with an Allison transmission reliably IMHO Ben's box is hands down the only option out there. Congrats Ben, many have tried and many have failed :thumb::thumb::thumb:
