Service Book says the blocker valve prevents shifting to reverse over 20 mph. Small piston that moves under pressure, limiting valve travel. Anyone have experience with it sticking?

Why is it sticking? If it's bent, you need to find another one. If it just has a rough spot or burr, use a stone to carefully file off the bad spot. If the valve body is scored, you may have to get another valve body. Good Luck!
