Circuit/System Verification
1. Verify the transmission fluid level, color and odor is correct.
2. Operate the vehicle to induce a shift from fifth to sixth gear while observing the following scan tool parameters. The scan tool parameters has
to change the proper value referring to the current gear, compare the proper values with: Transmission System Description and Operation
(M36 and MXE) (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Description and Operation/AF40-6 - Automatic
Transmission/Transmission System Description and Operation (M36 and MXE)). Perform this action 2 times.
* Clutch Pressure Control Solenoid Valve 1 Current
* Clutch Pressure Control Solenoid Valve 2 Current
* Clutch Pressure Control Solenoid Valve 3 Current
* Brake Band Pressure Control Solenoid Valve Current
* Shift Solenoid Valve 1
* Shift Solenoid Valve 2
瀚慖f the scan tool parameter does not change the proper value and no other DTCs than P0729, P0731, P0732, P0733, P0734, P0735, P0736,
P0780, P1731 are set, go to Circuit/System Testing.
瀚慖f any other DTC is set, diagnose that DTC first.
Circuit/System Testing
Dynamic Test
1. Perform the line pressure check. Refer to Line Pressure Check (See: Transmission and Drivetrain/Automatic
Transmission/Transaxle/Testing and Inspection/Symptom Related Diagnostic Procedures/AF40-6 - Automatic Transmission/Line Pressure
Check).
2. Perform the transmission fluid check. Refer to Transmission Fluid Level and Condition Check (See: Transmission and Drivetrain/Automatic
Transmission/Transaxle/Testing and Inspection/Symptom Related Diagnostic Procedures/AF40-6 - Automatic Transmission/Transmission
Fluid Level and Condition Check).
3. If all circuits test normal, replace the K71 Transmission Control Module. Verify the DTC does not reset.
瀚慖f the DTC resets replace the control valve body.
