Have you taken a look at your connectors to make sure a wire or pin hasn't worked loose? I've heard cases (though rare) where that's happened. I think the 68rfe has three harness connectors. Not sure about the aisin (I'm guessing it's an AS68rc based on your year though). Maybe give a call to revmax, suncoast, or ats and see if they have any ideas. They all have builds for the AS69 and revmax also offers a built AS68, so they may have a better idea. If you have the ability to pull TCM codes, that'll probably be useful as well.
