Code P2724 Buick Description

The clutch pressure control solenoid 5 is part of the control solenoid valve assembly, which has no serviceable parts. The Clutch Pressure Control Solenoid 5 regulates transmission fluid pressure 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 Transmission Control Module compares the expected transmission gear ratio to the calculated gear ratio for each commanded gear.
The Diagnostic Trouble Code (DTC) will be set when the Transmission Control Module has detected an incorrect gear ratio change when the 1-2-3-4 clutch is commanded OFF during a shift. This condition must occur 3 times.
