Arrow: Gap seal

Design

The torque converter lockup PWM solenoid valve is sealed by an O- ring and gap seal (arrow) towards the shift plate valve housing. The contact springs on the PWM converter lockup solenoid valve engage in a slot in the conductor tracks. The spring force of the contact springs means that reliable contacting is guaranteed.

Function

It converts a pulse-width modulated current actuated by the ETC [EGS] control unit (N15/3) into the corresponding hydraulic torque converter lockup control pressure.
