PCS 26 clutch fluid moves the 2-6 clutch regulator / gain

shift. For a 1-2 shift, PCS 26 clutch fluid pressure acts on a
input to output pressure magnification factor) of the 26 clutch
The 2-6 clutch regulator gain valve allows the gain (valve

26 clutch fluid from the 2-6 clutch regulator valve is routed
26 clutch fluid circuit where it passes through orifice #41
and then to the spring end of the 2-6 clutch regulator valve,
through the center support and to the 2-6 clutch piston
assembly. 26 clutch fluid pressure moves the piston against
the valve. 26 clutch/1234 clutch feed fluid is routed into the
force to allow 26 clutch/1234 clutch feed fluid to pass through
