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

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

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

assembly electrical connector.

3. Ignition ON, test for 8.3-9.3 volts between the ISS/OSS voltage circuit terminal B on the Q8 control solenoid valve assembly and ground at

the transmission case.

瀚慖f not within the specified range, replace the control solenoid valve assembly.

4. Perform the Control Solenoid Valve and Transmission Control Module Assembly Input Shaft Speed/Output Shaft Speed Input Test (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 Input

Shaft Speed/Output Shaft Speed Input Test).

5. Inspect the machined teeth on the 1-2-3-4 and 3-5 clutch housing outer surface for damage or misalignment. Repair or replace as necessary.

6. If all of the above test normal, replace the B14A/B14C ISS/OSS assembly.

Repair Instructions
