#3 Pressure Switch
WARNING: This page is about a different variant/trim than selected.
With the actuator feed limit/backfill passage closed at the shift solenoid valve - mode A, actuator feed limit/backfill fluid pressure increases to actuator feed limit pressure. PS3 fluid pressure, fed by actuator feed limit/backfill pressure through the hybrid direct, 2-3-4 clutch regulator valve, also increases. PS3 fluid opens the normally closed #3 pressure switch, signaling the TCM that the transmission is in EVT Mode High.
