I was in a hurry when I wrote that up but I remembered this thought this morning. The main reason for that test drive was because I was having trouble with the 50-WOT auto down-shift. It was delaying for some reason on my last two drives. I was going to go out and test the auto down-shift at different speeds to see if I could find a pattern.
I added this to my original post, does this lead to a loose band?

Thanks for your reply.
