Code P0796 2018 Chevrolet Silverado Description

The clutch pressure control solenoid 3 is part of the control solenoid valve assembly, which has no serviceable parts. The Clutch Pressure Control Solenoid 3 regulates transmission fluid pressure to the CBR1/C 4-5-6 clutch regulator valve which controls pressure to the low/reverse clutch and the 4-5-6 clutch. The Transmission Control Module 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 or neutral condition when the low and reverse clutch and the 4-5-6 clutch is commanded ON. This condition must occur 3 times.
