The oil, which is supplied to the 102 port, connects to the 103 port, 104 port (clutch valve spool). Oil pushing the spool
above, as a result, clutch B is released.
Clutch F engaged
EDS 5 switched ON. The line pressure which passed through the reduction valve flow to the 52 port of the holding valve, the 55,56 ports of the
clutch valve upper input port. As a result valve spool pressed.
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.
