Shift Solenoid "D" Control Circuit
DESCRIPTION
Shifting from 1st to 5th is performed in combination with "ON" and "OFF"
operation of the shift solenoid
valves SL1, SL2, SL3, S4 and SR which are controlled by the ECM. If an open or
short circuit occurs in
either of the shift solenoid valves, the ECM cont ...

Shift Solenoid "E" Performance (Shift Solenoid
Valve SR)
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 ...
