So I recently bought a TA that has a "reverse valve transmission" in it.

To me that meant nothing, until I saw the car and realized that I have to shift without a clutch.

Anyhow, I was wondering if it has a name or brand, how many styles are there and when someone asks what kind of reverse valve transmission is in your car, what do I say?

Maybe there is more than 1 kind I was just curious... If this make no sense at all disregard it!
