It should affect both. In the old, 5 chain system, the solenoid`s pin moves about 2 mm total, this operates a small plastic piston that opens and closes small oil passages inside the actuator. Oil flowing in these passages will control to which direction the large piston will move.

Thanks for this and good to know...had assumed it was only 3-chain that was affected
