* DTC P06AE has not set this ignition cycle.
Conditions for Setting the DTC
P06AC
* The difference between the transmission fluid temperature (TFT) and TCM power up temperature is greater than 20-50掳C (36-90掳F),
depending on the average of the TFT, TCM substrate, and TCM power up temperatures.
* The difference between the TCM substrate temperature and TCM power up temperature is greater than 8-10掳C (14-18掳F) depending on the
average of the TFT, TCM substrate, and TCM power up temperatures.
* The above conditions have to be met for 5 minutes within a 6 minute period.
P06AD
The TCM power up temperature is -59掳C (-74掳F) or less for 1 minute.
P06AE
The TCM power up temperature is 165掳C (329掳F) or greater for 1 minute.
Action Taken When the DTC Sets
* DTC P06AC, P06AD, P06AE are Type B DTCs.
* The TCM defaults the TCM power up temperature to the TCM substrate temperature.
Conditions for Clearing the DTC
DTC P06AC, P06AD, P06AE are Type B DTCs.

Circuit/System Verification
1. Engine idling at normal operating temperature, verify the scan tool TCM Power up Temperature parameter is between -59 and +165掳C (-74
and +329掳F).
2. Operate the vehicle at 64 km/h (40 mph) for 10 minutes. Monitor the TCM Temperature, TCM Power up Temperature, and the Trans. Fluid
Temp. parameters with a scan tool. The TCM Temperature and the Trans. Fluid Temp. parameters should be within 20掳C (36掳F) of each
other, and the TCM Temperature and TCM Power up Temperature parameters should be within 10掳C (18掳F) of each other.
瀚慖f the TCM Temperature and TCM Power up Temperature parameters are not within 10掳C (18掳F), or the TCM Power up Temperature
and Trans. Fluid Temp. parameters are not within 20掳C (36掳F), replace the control solenoid valve assembly.
3. 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.
Repair Instructions
Note:
* 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).
