Circuit/System Verification

1. Perform the Transmission Fluid Level and Condition Check (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing

and Inspection/Symptom Related Diagnostic Procedures/2ML70 - Automatic Transmission/Transmission Fluid Level and Condition Check)

to verify correct fluid level.

2. Perform the Line Pressure Check (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and Inspection/Component

Tests and General Diagnostics/2ML70 - Automatic Transmission/Line Pressure Check) to verify correct oil pressure.

3. Perform the Control Solenoid Valve and Transmission Control Module Assembly Solenoid Performance Test (See: Transmission and

Drivetrain/Automatic Transmission/Transaxle/Testing and Inspection/Component Tests and General Diagnostics/2ML70 - Automatic

Transmission/Control Solenoid Valve and Transmission Control Module Assembly Solenoid Performance Test).

4. Inspect the hybrid direct, 2-3-4 clutch regulator valve for sticking or damage.

瀚慖f you found a concern with the hybrid direct, 2-3-4 clutch regulator valve, repair or replace the valve or valve body.

5. Inspect the hybrid direct, 2-3-4 clutch for a stuck On or damaged condition.

瀚慖f you found a hybrid direct, 2-3-4 clutch concern, repair or replace the hybrid direct, 2-3-4 clutch assembly as necessary.

Repair Instructions
