automatic valve body vs. manual valve body

They are mostly just like they sound…

An automatic valve body shifts automatically…. Like automatic transmissions normally do. Including a stock Torqueflight.

A manual valve body changes things so your automatic must be shifted manually and provides more positive shifting.


People go both ways an which to chose in a street application. Some like a manual valve body on the street, others say they are to harsh shifting for their taste and/or want their automatic to work like an automatic not a clutch-less 3 speed.

So… The choice is a matter of taste.
