* Before replacing the TCM, perform the Control Solenoid Valve and Transmission Control Module Assembly Inspection (See:

Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and Inspection/Component Tests and General

Diagnostics/6T70/6T75 - Automatic Transmission/Control Solenoid Valve and Transmission Control Module Assembly Inspection).

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

* Control Valve Lower Body and Upper Body Replacement (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Valve

Body/Service and Repair/6T70/6T75 - Automatic Transmission/Control Valve Lower Body and Upper Body Replacement)

DTC Descriptors

DTC P2723

- Clutch Pressure Control (PC) Solenoid 5 - Stuck Off

DTC P2724

- Clutch Pressure Control (PC) Solenoid 5 - Stuck On

Circuit/System Description

The clutch pressure control (PC) solenoid 5 is part of the control solenoid valve assembly, which has no serviceable components. The clutch PC

solenoid 5 regulates the transmission fluid pressure (TFP) to the 1-2-3-4 clutch regulator valve, which controls pressure to the 1-2-3-4 clutch. The

transmission control module (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.
