Blows me away what expectations some people have for stock parts, the 10R80 is a great transmission and holds around 850 rwhp in stock form just don't let it shift into 7th gear. That transmission doesn't owe you shit it's handling over double the hp the car is designed to make, if you are going to cry about it go buy a fox body and run a PG.
It's designed for 650, IIRC. The rest, 100% spot on.
I'll be honest, this is my first Mustang and also first Ford product I've ever owned and have been heavily involved with GM/BMW/Mercedes cars and have modded and blown up my fair share and can speak with confidence differences between years, engines, generations etc. With Mustangs I thought I was up to speed with the differences and thought they weren't that big of a deal at a glance. I was told by people with 2015-2017's that everything should be the same and bolt right up and there isn't anything complicated between the two years just a trans change etc etc. So I was under the impression a 2017 turbo kit would bolt right on to 2018+, a fuel system would be abundant and reasonably priced, and that Trans parts would be readily available. Since the 2018s had been out for a full year at that point and at least in the GM camp, thats ample time for new/modified tech to hit the market and is readily available and typically more than 1 vendor had a solution.
SPOT ON. It's impressive as hell the motor and trans live at 850+ and its a common thing and not some one off one hit wonder. So I'm already blown away by that aspect and durability, just sorta surprised its been over a year now and nothing exists yet as far as built parts goes.
