My wife and I test drove a new 2017 with 4.10s last week. I put it thru several full power runs up to 60mph. The 4.10 surely is a strong runner. I did notice one thing for sure. You have to be real attentive at shift times. Just a micro second before the shift I think the engines ability to TQ manage kicks in and defuels just a bit. Is this a protection device? Or is it just the feel you get all caused by the aisin? The shift was positive but not as strong as my Suncoast 68RFE.
