Well guys, I traded in my 2016 68rfe dually, for an Aisin equipped 2019 dually. I love the fact that the Aisin just locks up and goes without any of the TC flare that I had with the 68rfe. I had an MM3 with Ray's tuning on my last truck and am planning the same for this one. Any news on 2019 tuning or if anyone has made any headway in cracking the Aisin? I know Randy Reyes hammers his Aisin without any tuning, but I'm sure that being able to customize the maps will push this transmission into new territory. Thanks as always.
