If you put the transbrake valve body back in,and DON'T put any voltage to the solenoid on the trans,then you will have a full manual shift powerglide minus the trans brake option.What the transbrake does is apply the reverse clutches when in a forward gear. When the button on the shifter is pressed,it activates the solenoid to apply those clutches and keeps the car motionless,since the forward AND reverse clutches are both applied.Release the button,reverse clutches are no longer applied,and the car goes forward[rather quickly at 5500 RPM,I might add] If the button is not pressed,it is just a regular full manual shift trans. But I have no idea,you would know more than me, if shift harshness in a boat application would be a concern.
