Shift Solenoid Pre-Diagnosis

Shift Solenoid Pre-Diagnosis
Use the shift solenoid operation chart when carrying out Pinpoint Test A. Refer to Specifications. Test A: Shift and Torque Converter Clutch Solenoids (Only)

Solenoid Operation Chart - Converter Engaged

Solenoid Operation Chart-converter Engaged:

With a on/off solenoid, OFF = No Hydraulic Flow.
With a PWM solenoid, OFF = Full Hydraulic Flow.
PCA and PCB PWM solenoid percentage varies through all gears.

Solenoid Operation Chart - Converter Disengaged

Solenoid Operation Chart-converter Disengaged:

With a on/off solenoid, OFF = No Hydraulic Flow.
With a PWM solenoid, OFF = Full Hydraulic Flow.
PCA and PCB PWM solenoid percentage varies through all gears.
