• The cutback valves are composed of cutback valve A and B.
• Coasting clutch pressure (28) is applied to the left side of cutback valve A, and line pressure (7) controlled by the shift solenoid A is applied to the right side of cutback valve A. Modifier pressure (21) is applied to cutback valve B.
• When coasting clutch pressure (28) or line pressure (7) is applied, the cutback valve B moves to the right, closing the modifier pressure (22) circuit.
• When either coasting clutch pressure (28) or line pressure (7) is working, the modifier pressure (22) circuit opens to apply pressure to the right of the pressure regulator valve. As a result, the pressure regulator valve is pushed to the left side, lowering line pressure. This condition is called "cutback".
