* The transmission line pressure is greater than 370 kPa (54 psi) and not fluctuating by greater than 30 kPa (4 psi).
* Propulsion is active.
P0776
The clutch pressure control solenoid 2 commanded pressure is greater than 1800 kPa (261 psi) for 4.5 seconds.
P0777
The clutch pressure control solenoid 2 commanded pressure is less than 5 kPa (1 psi) for 4.5 seconds.
Conditions for Setting the DTC
P0776 - Fail Case 1
The clutch pressure control solenoid 2 commanded pressure is 1800 kPa (261 psi) and the transmission fluid pressure switch 3 state is Low for 30
seconds.
P0776 - Fail Case 2
The clutch pressure control solenoid 2 commanded pressure is 1800 kPa (261 psi) and the transmission fluid pressure switch 3 state is Low for 0.5
seconds greater than 5 times during a key cycle.
P0777 - Fail Case 1
The clutch pressure control solenoid 2 commanded pressure is 5 kPa (1 psi) and the transmission fluid pressure switch 3 state is High for 36
seconds.
P0777 - Fail Case 2
The clutch pressure control solenoid 2 commanded pressure is 5 kPa (1 psi) and the transmission fluid pressure switch 3 state is High for 1.25
seconds greater than 5 times during a key cycle.
Action Taken When the DTC Sets
* P0776 and P0777 are Type B DTCs.
* The transmission control module commands maximum line pressure.
* The transmission control module freezes transmission adaptive functions.
Conditions for Clearing the DTC
P0776 and P0777 are Type B DTCs.
Diagnostic Aids
When attempting to set transmission performance DTCs, observe the Freeze Frame and Failure Records to assist in duplicating the failure
conditions. With a scan tool, monitor the PC Sol. 2 Pressure Command and the TFP Switch 3 state parameters. Operate the vehicle in drive to
obtain 72 km/h (45 mph) for at least 10 seconds, stop the vehicle, turn the ignition Off for at least 30 seconds. Perform this operation 2 times. When
the PC Sol. 2 Pressure Command is Yes, the transmission fluid pressure switch 3 state should be high. When the PC Sol. 2 Pressure Command is
No, the TFP switch 3 state should be Low.
