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.

Repair Instructions

Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.

* Control solenoid valve assembly replacement. Refer to Control Module References (See: Testing and Inspection/Programming and

Relearning) for replacement, setup, and programming.

* Perform the Service Fast Learn Adapts (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and

Inspection/Programming and Relearning/Service Fast Learn Adapts) following all transmission related repairs.

P2715

DTC P2714 or P2715

DTC Descriptors

DTC P2714

- Clutch Pressure Control (PC) Solenoid 4 - Stuck Off

DTC P2715

- Clutch Pressure Control (PC) Solenoid 4 - Stuck On

Circuit/System Description

The clutch pressure control (PC) solenoid 4 is part of the control solenoid valve assembly, which has no serviceable parts. The PC solenoid 4

regulates transmission fluid pressure to the 2-6 clutch regulator valve which controls pressure to the 2-6 clutch. The TCM calculates gear ratio

based on the RPM signals from the input speed sensor (ISS) and the output speed sensor (OSS). The TCM compares the expected transmission gear

ratio to the calculated gear ratio for each commanded gear.
