The reason I ask is that I don't like the way the 727 in my 440+6 GTX shifts. It shifts unlike any stock 727's I have had in the past so I suspect maybe the valve body was changed sometime in the past. I don't know the history of the trans but it is the original numbers trans to the car. I would like to have the car shift like a stock trans would as the car is otherwise all stock anyway. I have a 70 727 trans from a full size Chrysler and thought if they used the same valve body I might swap them with each other.
