GF27.19-P-5177ACK Torque Converter Lockup Clutch Control Solenoid Valve, Component Description

GF27.19-P-5177ACK Torque converter lockup clutch control solenoid valve, component description
- Transmission 722.695

Component Identification:

Location
The PWM solenoid valve is located on the supporting body of the electric controller unit and is pressed against the valve housing of the valve body assembly by a leaf spring.

Task
The PWM solenoid valve controls the pressure for the torque converter lockup clutch.

Component Identification:

The PWM solenoid valve is sealed by an O-ring and gap seal (arrow) towards the valve housing of the valve body assembly.

The contact springs on the PWM solenoid valve grip in a slot in the conductor tracks. The spring force of the contact springs means that reliable contacting is guaranteed.

Function
The PWM solenoid valve converts a pulse width modulated current actuated by the ETC control unit (N15/3) into the corresponding hydraulic torque converter lock-up clutch control pressure.
