COMPONENTS
(1) OIL PUMP
A trochoid type gear oil pump has been adopted.
The oil pump consists of an oil pump body, an oil pump drive
gear, and an oil pump driven gear. The oil pump drive gear,
which is driven by the torque converter, drives the oil pump
driven gear to send the automatic transmission fluid to the hy-
draulic pressure control system under a pressurized state.
(2) VALVE BODY
The valve body is mounted at the lower surface of the trans-
mission. It incorporates hydraulic pressure-regulating valves,
such as a throttle valve, a regulator valve, a modifier valve, a
secondary regulator valve, and a throttle modulator valve. It
also incorporates a manual valve, and valves that will switch
fluid passages of each shift valve, thus reducing gear shift im-
pacts of each timing valve, etc.
1) Manual valve
The manual valve is interlocked with the shift lever by the con-
trol cable. According to the shift lever movement, the manual
valve switches the line pressure of each range.
