The TFT has not changed more than 20掳C (36掳F) during the following conditions:
* The TFT temperature at start up is -50掳C (-58掳F) for 42 minutes.
* The TFT temperature at start up is -25掳C (-13掳F) for 17 minutes.
* The TFT temperature at start up is -10掳C (14掳F) for 14 minutes.
* The TFT temperature at start up is -5掳C (23掳F) for 9 minutes.
* The TFT temperature at start up is 20掳C (68掳F) for 4 minutes.
P0712
The TFT is -74掳C (-101掳F) or less for 13 seconds or more.
P0713
The TFT is 174掳C (345掳F) or greater for 10 seconds or more.
Action Taken When the DTC Sets
* DTCs P0711, P0712, and P0713 are Type C DTCs.
* The TCM freezes transmission adaptive functions.
* The TCM allows the vehicle to operate in transmission protection mode.
Conditions for Clearing the DTC
DTCs P0711, P0712, and P0713 are Type C DTCs.
Diagnostic Aids
During a road test, the transmission fluid temperature (TFT) should steadily increase to a normal operating temperature, and then stabilize.

Circuit/System Verification
1. Engine idling at normal operating temperature, verify the scan tool Trans Fluid Temp. parameter is between -74 and +174掳C (-101 and +345掳
F).
瀚慖f not within the specified range, replace the Q8 control solenoid valve assembly.
2. Operate the vehicle at 64 km/h (40 mph) for 10 minutes. Monitor the Transmission Fluid Temperature parameter and the TCM Temperature
