Pressure Control Solenoid "A" Performance (Shift Solenoid Valve SL1) (P0746,P0771)
DESCRIPTION
The ECM uses signals from the output shaft speed sensor and input 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 mech ...
