the only other thing that could be happening is the fluid is pushing back through the valve body when it's in the "hold" position... pull the stem out and see if there are "O" rings on it... never had a valve section apart on a T40 ... not sure what's on the stem of the valve.
I just replaced a valve section on one of my Posi Plus units.... $1200.00 for the section and the stem.
