Timing Solenoid
Timing solenoid is installed directly in the valve body. The
solenoid operates of ON/OFF by the control signal from
TCM. The solenoid change timing valve of inside the valve
body, operate hydraulic control with apply and drain of for-
ward clutch.
Lock–Up Solenoid
Lock–up solenoid is installed in the valve body. It recieves
control signal from TCM.
Lock–up solenoid operates the lock–up valve inside the
valve body and controls the torque converter lockup func-
tion.
Pressure Control Solenoid (PCS)
The pressure control solenoid (PCS) is located inside the
valve body and regulates the transmission’s fluid pressure
system. It is internally grounded in the TCM and operates
when it is supplied with battery voltage from the TCM,
through the PCS and back to the TCM.
The battery voltage is controlled by a varying current from
the TCM.
The strength of the current is a function of the throttle posi-
tion.
Transmission Fluid Temperature (TFT)
Sensor
TFT sensor provides TCM with information on the trans-
mission fluid temperature.
The TCM uses information from the TFT sensor to calcu-
late the gear shift points and to engage the torque convert-
er lockup function.
Input Shaft Speed (ISS) Sensor
ISS sensor is located on the upper position of the transaxle
and detects A/T input speed from the rotation number of
the direct clutch drum.
They transmit to TCM as a signal.
