Absolutely!!! Will give all details of how the tranny shifts, launches and cruises. I only have 3:08s in the rear end but I have a brand new set of 4:10s in the box ready to install. I wanted to make sure the tranny works as it's supposed to before changing the gears. If I hear any strange noises I don't want to be wondering if it's the tranny or the new gears....one problem at a time!!
