Automatic transmission torque converter lock-up solenoid valve
Function:
* Torque converter lock-up control
* Improved engine power transfer to the gearbox
Working principle:
* An electromagnet converts an electrical signal into a mechanical action.
* When the electromagnet is activated, it creates a magnetic field that moves the plunger.
* The plunger opens or closes the hydraulic passage, directing the flow of transmission fluid.
Peculiarities:
* Usually installed on the torque converter housing or on the automatic transmission housing.
* Works with the automatic transmission control unit and vehicle speed sensors.
* Important component for smooth torque converter lock-up and improved fuel efficiency.
Components:
* Electromagnet
* Plunger
* Hydraulic channel
* Electrical connector
Control:
* The automatic transmission control unit sends an electrical signal to the solenoid valve.
* The signal determines whether the torque converter lock-up is turned on or off.
Malfunctions:
* Faulty electromagnet
* Clogged hydraulic channel
* Break in electrical wiring
* May cause torque converter lockup problems, which reduces fuel economy and performance.
Service:
* Clean the hydraulic passage and electrical connectors.
* Replace faulty components as needed.
*Check the torque converter lock-up system regularly.
