Perhaps you can go through and print relevant posts from this forum where you mentioned each ATF change as sufficient evidence?
That's a good idea, since there are time/date stamps for the updated posts, along with a photo of the drain plug at the first change floating around.
I actually did make a print out of the MM sequence that I have posted with mileage and code, along with my digital documentation of the transmission issues by date of when they occurred. When I handed it to the tech, he looked at it, and asked me where I found it. I told him it's my personal record of maintenance for this vehicle and I could see the gears spinning in his head. The service advisor photocopied the sheet and attached it with a print out of the codes their computer found.

I feel like with regular maintenance, even 100k is a short life in a modern vehicle. I am wondering if these 6 speeds have some sort of finite # of shifts before they start gong bonkers. I almost feel like perhaps I made it to 142k, where others are imploding at far less mileage, just because the vast majority of my driving is going from gears 1-6 and then sitting in 6th for 30+ mile stretches.
