Condition

Some customers may comment on a loss of forward gear, slipping, and/or a check
engine light on.
Technicians may nd the following DTC set in the Transmission Control Module
(TCM)
P2714: Transmission Control Solenoid Valve 4 Stuck O

Cause

Note: This condition may be intermittent or not reproduceable
This condition may be caused by the clutch regulator valve sticking in the valve body;
Damage to the forward clutch piston and/or wear in the Primary Pulley Bearing Bore
causing damage to the case.

Correction:
Verify DTC P2714 is set current or history .
Verify the transmission uid is at the proper level following document 4818020.
Note: The transmission uid temperature must be between 60°-80°C (140°-176°F) to properly check the uid level
and to perform the following procedures.
If the uid level is correct, with the transmission at operating temperature, drive the vehicle and see if there is a
slip or lack of engagement in drive.
If there is no slip in drive, clear the DTC’S.
Drive the vehicle, making sure the vehicle is at operating temperature.
If the DTC does not immediately reset and there is no slip condition or no loss of drive felt, perform 3 to 4 WOT
accelerations.
If the DTC does not reset, replace the valve body (Not the solenoid valve body) and re-evaluate.
If DTC P2714 resets, check the following:

No forward motion but does have reverse
Slips under heavy acceleration
The DTC or the concern is repeatable
If there is a drop in Primary and Secondary pulley pressure drop due to leak
Or if the Primary and Secondary Pulley pressure drop on auto stop
-Pressure on auto stop should be around 400 kPa
-If below 300 kPa there could be piston seal leak
If there is a loss of drive, slipping, the uid has a burnt odor, or any of the above indicators are present, the
transmission will need to be disassembled and inspected.
With the transmission disassembled, inspect the Forward Clutch Piston for damage along the side as shown.

If the Forward clutches are worn and there is damage seen to the Forward Clutch Piston then replace the Foward
Clutch Piston and Housing and the applicable apply components as needed
If there is no damage to the Forward Clutch Piston, inspect the pump for signs of wear.
Note: The rst 2 pictures show the outside of the pump, and the second 2 pictures show the wear that is found
internal to the pump when wear to the Primary Pulley Bearing Bore is found .

If signs of wear are seen as shown, this indicates the Primary Pulley Bearing has spun in the bore and is allowing
the Turbine Shaft to become o center When this happens, it causes a pressure leak.
If this concern is found, the transmission will need to be replaced.
Note: The Primary Pulley Bearing is installed on the inside of the case on the primary pulley, this area of the
transmission cannot be accessed for inspection, inspection of the pump for DTC P2714 and no concern found
with the Forward Clutch Piston is critical.
