Pressure Control Solenoid "D" Performance (Shift
Solenoid Valve SLT)
SYSTEM DESCRIPTION
The linear solenoid valve (SLT) controls the transmission line pressure for
smooth transmission operation
based on signals from the throttle position sensor and the vehicle speed sensor.
The ECM adjusts the
duty ratio (*) of the SLT solenoid valve to control hydraulic line ...

Shift Solenoid "D" Performance (Shift Solenoid
Valve S4)
SYSTEM DESCRIPTION
The ECM uses signals from the vehicle speed sensor to detect the actual gear
position (1st, 2nd, 3rd, 4th
or 5th gear).
Then the ECM compares the actual gear with the shift schedule in the ECM memory
to detect mechanical
problems of the shift solenoid valves, valve b ...
