I have been playing around with this valve body in a Lighting. Boy is it sweet NOT to have the computer control the transmission.

I subscribed to your channel and have been watching the progress as well. While I don't want to lose electronic control of my trans, it would be nice to have a transbrake for my turbos.

What kind of Hp has it been tested with?
From videos it looks like a stock gen2 lightning drivetrain swapped f150. So like 350 rwhp maybe. Interested to see how it holds up to 1000+ rwhp applications.

+1 and for how long it lives in 1k rwhp trucks
We have plans of installing the valve body in a 7000 lbs Diesel truck that is making 1000 just in torque. The valve body does not require a computer, the 3rd gear check ball is .500 compared to the stock .250 ball. Because the valve body is billet aluminum and not cast, I designed the passages to have a smooth rounded arks for maxim flow. The valve body will not have any limitations, but the transmission will.

Good to know. I figured it "should" be fine as there aren't really any moving parts. Only thing I can even think of is the pressures being correct. I know electrically I can control them now and vary pressure to where/when it's needed. But I'm assuming in a manual VB it's just set at a certain pressure? I'm definitely intrigued by the idea of it given the transbrake and my turbos.
