Automatic Transmission/Control Solenoid Valve and Transmission Control Module Assembly Solenoid Performance Test). Test all solenoids
on the Q8 control solenoid valve assembly. A pressure change should occur for each solenoid valve.
瀚慖f the Q8 control solenoid valve assembly does not pass the performance test, replace the Q8 control solenoid valve assembly.
4. Listed in the chart below, are conditions for each component that could set DTC P2714 or P2715. Carefully inspect each component for that
condition. Repair or replace as necessary.

DTC Descriptors
DTC P2714
- Pressure Control (PC) Solenoid 4 - Stuck Off
DTC P2715
- Pressure Control (PC) Solenoid 4 - Stuck On
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
