SOLENOID VALVE

DESCRIPTION

E2DBB4CE

TCM calculates the best condition using the information
from all kinds of sensors. If the solenoid valve receives the

information on the oil pressure, the solenoid valve actuates
according to the driving signal. All kinds of regulators in
the valve body are controlled to change the oil passage
and also the line pressure is controlled by TCM.

● PWM (Pluse Width Modulation) SOLENOID VALVE

Structure and functions

PWM solenoid valve is composed of five solenoid valves
and the oil capacity in the solenoid valve is changed by the
electric duty value of TCM. The oil pressure of the valve
body and the torque converter engages or disengages the
damper clutch. The solenoid valves send the operating oil
pressure to the clutches and brakes at the each range and
also control the strength and weakness of oil pressure to
reduce the shock when shifting the range.

VFS(VARIABLE FORCE
SOLENOID) VALVE

DESCRIPTION

E9FA1D98

VFS valve controls the regulator valve and varies the line
pressure from 4.5bar to 10.5bar according to the throttle
open angle and the shift range. The holder is installed on
the upper side of the case and the filter is installed to the
two places on the holder outside to prevent in the strange
material from flowing in the VFS.
