tystevens,
I suspect much of the downshifting is due to the auto transmission. I have had many vehicles, only one, a Pontiac in the 80's with a auto. All the downshifting is unnerving to me.
It isn't so much the downshifting that bothers me. It's the hunting. I've heard some vehicles give the driver the ability to control this hunting. Do any of your vehicle have the ability to do this.
It seems that it is only the big diesels that are going to stop the constant shifting. From watching the videos on big diesel testing It seems they do good job.
