In Reverse, solenoid is switched ON and EDS 4 switched OFF. So the oil which is supplied to reduction valve is flow to the 42 port of the clutch
valve D via the 40, 41 port of the EDS 4.
The spool of the clutch valve pressed to below. So line pressure flow to the 95 port via the 93, 94 port. As a rule, valve spool push against
direction.
Lock up clutch
Solenoid valve 2 switch ON, line pressure control valve spool compressed, flow to the 131port via 130 port of the torque converter pressure
valve.
As a result, the oil pressure behind the converter lockup clutch piston and in the turbine zone is equal. The direction of flow is through the turbine
shaft and through the space behind the piston, to the turbine chamber.
Lubrication, cooling
The lubricating valve ensures that the converter is supplied with cooling oil first if the pump rate is low. The lubricating pressure valve in addition
guarantees that the necessary amount of cooling and lubricating oil is available via the bypass duct.
The oil which is supplied from torque converter flow to 135 port via 133,134 port, and flow to cooler via lubrication valve.
