Conditions for Setting the DTC
P2728
The transmission control module detects an internal electrical performance malfunction of the clutch pressure control solenoid 5 control circuit
when the actual pressure does not equal the commanded pressure for 5 seconds.
P2729
The transmission control module detects an internal low voltage electrical malfunction of the clutch pressure control solenoid 5 control circuit for
500 milliseconds.
P2730
The transmission control module detects an internal high voltage electrical malfunction of the clutch pressure control solenoid 5 control circuit for
500 milliseconds
Action Taken When the DTC Sets
* DTC P2728 is a Type B DTC.
* DTCs P2729 and P2730 are Type A DTCs.
* The transmission control module defaults the transmission to a limited shift pattern utilizing 2 forward gears and reverse based on the default
detected.
* The transmission control module commands maximum line pressure.
* The transmission control module freezes transmission adaptive functions.
Conditions for Clearing the DTC
* DTC P2728 is a Type B DTC.
* DTCs P2729 and P2730 are Type A DTCs.
Diagnostic Aids
When attempting to set solenoid electrical DTCs, ensure the TCM is warmed up and the transmission is operated long enough to ensure a 3掳C (5掳F)
increase in TCM temperature parameter. This will place the transmission control module in the optimal conditions to test solenoid electrical DTCs.
