sorry to resurrect, but I wanted to update. I switched from Lund to Bama (my friend is their new senior calibrator and I've been helping him test some things) and I haven't had the issue since switching to Bama.
I'm convinced it's something Lund has it in the tune that my car isn't agreeing with. Been Bama tuned for about 6 months and no trans issues whatsoever.
You should let Lund know that for sure.
