Transmission Electronic Control System: Solenoids

The hydraulic module contains one solenoid valve. The solenoid valve is activated by the TCM and is either open or closed. It is used to switch the position valve.

There are 6 electronic pressure control valves which convert an electronic current into a proportional hydraulic pressure. They are energized by the TCM and actuate the valves belonging to the relevant switching elements.

Solenoids VFS1, VFS3 and VFS6 are proportional in operation, meaning that hydraulic pressure increases with an increase in current. Solenoids VFS2, VFS4 and VFS5 are inversely proportional in operation, meaning that hydraulic pressure decreases with an increase in current. Solenoid SS1 is a shift solenoid having a ON/OFF operation.
