Lubricating Pressure (p-SM)

This pressure limits the pressure in torque converter and lubricates and cools the mechanical transmission parts.
At the operating pressure control valve, excess fluid is diverted to the lubricating pressure control valve (1) and, from
there, regulated for transmission lubrication use (including torque converter).

Control Valve Pressure (p-RV)

The control valve pressure is set at the control pressure regulating valve (5) in relation to the operating pressure up to 8
bar.
This pressure supplies oil to modulating pressure (MP) solenoid valve, shift pressure (SP) solenoid valve, shift valve
pressure control valve (6).

Modulating Pressure (p-Mod)

The modulating pressure is adjusted at the modulating pressure control solenoid valve. The height of modulating pres-
sure is dependent on engine load by TCU. It acts on the operating pressure control valve and the pressure overlap control
valve. It increases the operating pressure (line pressure) when the load is heavy.

Shift Pressure (p-S)

The shift pressure is adjusted at the shift pressure control solenoid valve and shift pressure control valve (4). Additional
pressure from clutch C2 acts on the shift pressure control valve. As a result, the shift pressure in 2nd gear is reduced.
Shift Valve Pressure (p-SV)
The shift valve pressure converts the control valve pressure (p-RV) to shift valve pressure. Then it supplies oil to com-
mand valve, lockup solenoid valve, and shift pressure control solenoid valves.
