Note: You must perform the Circuit/System Verification first.

1. Ignition OFF, remove the Q8 control solenoid valve assembly. Refer to Control Solenoid Valve and Transmission Control Module Assembly

Replacement (See: Powertrain Management/Transmission Control Systems/Actuators and Solenoids - Transmission and

Drivetrain/Actuators and Solenoids - A/T/Shift Solenoid/Service and Repair).

2. Perform the Control Solenoid Valve and Transmission Control Module Assembly Inspection (See: Transmission and Drivetrain/Automatic

Transmission/Transaxle/Testing and Inspection/Component Tests and General Diagnostics/6L45/6L50/6L80/6L90 - Automatic

Transmission/Control Solenoid Valve and Transmission Control Module Assembly Inspection).

3. Place the Q8 control solenoid valve assembly on a clean work surface near the transmission assembly.

4. Connect DT-47825-10 - jumper harness between the vehicle wire harness electrical connector, and the Q8 control solenoid valve assembly

electrical connector.

5. Ignition ON, verify with a scan tool the following test status parameters display OK:

* Pressure Control Solenoid Valve 5 Performance Test Status

* Pressure Control Solenoid Valve 5 Control Circuit High Voltage Test Status

* Pressure Control Solenoid Valve 5 Control Circuit Low Voltage Test Status

瀚慖f any test status parameter displays Fault or Malfunction, replace the Q8 control solenoid valve assembly.

Repair Instructions

Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.

* Perform the Service Fast Learn Adapts (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and

Inspection/Programming and Relearning) following all transmission related repairs.

* Replace the control solenoid valve assembly. Refer to Control Module References (See: Testing and Inspection/Programming and

Relearning) for replacement, setup, and programming.
