Circuit/System Description

The clutch pressure control solenoid 4 is part of the control solenoid valve assembly and is not serviced separately. The transmission control

module supplies 12 volts to the clutch pressure control solenoid 4 through the high side driver 1 circuit. The transmission control module controls

the clutch pressure control solenoid 4 through the clutch pressure control solenoid 4 control circuit. The normally low clutch pressure control

solenoid 4 flows fluid to the 1-3 clutch when commanded ON and exhausts fluid when commanded OFF. The clutch pressure control solenoid 4

regulates the transmission fluid pressure to the 1-3 clutch.

Conditions for Running the DTC

* The engine run time is greater than 1 second.

* Shift solenoid valve 1 is not in a transition state.

* The transmission line pressure is greater than 370 kPa (54 psi) and not fluctuating by greater than 30 kPa (4 psi).

* Propulsion is active.

P2714

The clutch pressure control solenoid 3 commanded pressure is greater than 1800 kPa (261 psi) for 4.5 seconds.

P2715

The clutch pressure control solenoid 3 commanded pressure is less than 5 kPa (1 psi) for 4.5 seconds.

Conditions for Setting the DTC

P2714 - Fail Case 1

The clutch pressure control solenoid 4 commanded pressure is 1800 kPa (261 psi) and the TFP switch 4 state is Low for 30 seconds.

P2714 - Fail Case 2

The clutch pressure control solenoid 4 commanded pressure is 1800 kPa (261 psi) and the TFP switch 4 state is Low for 0.5 seconds greater than 5

times during a key cycle.

P2715 - Fail Case 1

The clutch pressure control solenoid 4 commanded pressure is 5 kPa (1 psi) and the TFP switch 4 state is High for 36 seconds.

P2715 - Fail Case 2

The clutch pressure control solenoid 4 commanded pressure is 5 kPa (1 psi) and the TFP switch 4 state is High for 1.25 seconds greater than 5 times

during a key cycle.

Action Taken When the DTC Sets

* P2714 and P2715 are Type B DTCs.

* The transmission control module commands maximum line pressure.

* The transmission control module freezes transmission adaptive functions.

Conditions for Clearing the DIC/DTC

P2714 and P2715 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.
