3-8 Clutch Applies
WARNING: This page is about a different car, the 2020 GMC Terrain and 2020 Chevrolet Equinox. However, it is still accessible from the selected car via links, so may be relevant.
VFS S3-8 Solenoid
The VFS S3-8 solenoid is energized allowing line fluid to enter the S38 VFS SIG fluid circuit. S38 VFS SIG fluid is directed to the 3-8 clutch regulator valve.
3-8 Clutch Regulator Valve
S38 VFS SIG fluid is directed thru orifice #5 and into the 3-8 clutch regulator valve where it applies pressure against the 3-8 clutch regulator valve spring force. This allows DRIVE 2 fluid to enter the 38 CLUTCH fluid circuit. 38 CLUTCH fluid seats ball check valve #3 then is forced thru orifice #31 and #30 to the 3-8 clutch assembly.
3-8 Clutch Assembly
38 CLUTCH fluid is directed to the 3-8 clutch assembly. 3-8 CLUTCH fluid moves the piston against spring force to apply holding of the 3-8 clutch plates.
