Q27B Pressure Control Solenoid Valve 2
WARNING: This page is about a different car, the 2019 Buick Cascada, 2018 Buick Cascada, and 2017 Buick Cascada. However, it is still accessible from the selected car via links, so may be relevant.
Pressure control solenoid valve 2 is a normally low pressure control solenoid valve. The solenoid valve regulates and directs fluid pressure to the 3-5-reverse clutch regulator valve. Increasing pressure to the 3-5-reverse clutch regulator valve increases pressure to the 3-5-reverse clutch.
