4. Record the Freeze Frame/Failure Records data. Clear the DTCs.
5. Engine running, brakes applied, transmission gear shift selector in reverse. Shift to drive and accelerate to 56 km/h (35 mph) with calculated
throttle position greater than 15 percent. Perform this test 5 consecutive times. The DTC should not set.
6. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the
conditions that you observed from the Freeze Frame/Failure Records data.
Circuit/System Testing
1. Perform the Line Pressure Check (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and Inspection/Component
Tests and General Diagnostics/6T70/6T75 - Automatic Transmission/Line Pressure Check). Verify the transmission line pressures are within
the range specified in the Line PC Solenoid Valve Pressure table. Refer to Solenoid Valve Pressure (See: Specifications/Mechanical
Specifications/Automatic Transmission/Transaxle/System Specifications/6T70/6T75 - Automatic Transmission/Solenoid Valve Pressure).
瀚慖f not within the specified ranges, refer to Fluid Pressure High or Low (See: Transmission and Drivetrain/Automatic
Transmission/Transaxle/Testing and Inspection/Symptom Related Diagnostic Procedures/6T70/6T75 - Automatic Transmission/Fluid
Pressure High or Low).
2. Ignition OFF, remove the 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).
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/6T70/6T75 - Automatic
Transmission/Control Solenoid Valve and Transmission Control Module Assembly Solenoid Performance Test). Test all solenoids on the
control solenoid valve assembly. A pressure change should occur for each solenoid valve.
瀚慖f the control solenoid valve assembly does not pass the performance test, replace the control solenoid valve assembly.
4. Listed in the table below are conditions for each component that could set DTC P0756. Carefully inspect each component for that condition.
Repair or replace as necessary.
Repair Instructions
Important:
* Perform the Service Fast Learn Adapts (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and
Inspection/Programming and Relearning) following all transmission related repairs.
* Before replacing the TCM, 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/6T70/6T75 - Automatic Transmission/Control Solenoid Valve and Transmission Control Module Assembly Inspection).
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
* Control Valve Upper Body Assembly Cleaning and Inspection (See: Transmission and Drivetrain/Automatic
Transmission/Transaxle/Service and Repair/Overhaul/50. Control Valve Upper Body Assembly Cleaning and Inspection)
* Control Module References (See: Testing and Inspection/Programming and Relearning) for control solenoid valve assembly replacement,
