Solenoid valve 5550

Solenoid valve designed for 55-50SN / 55-51LE / 55-51SN / AF23-5 / AF33-5 / AW50/51. It controls the oil flow in the hydraulic controller based on the signal from the transmission controller and determines the moment and smoothness of the gear change.

A damaged solenoid valve is manifested by hard or delayed gear changes, the transmission of the box to emergency mode and pressure errors in the controller memory. Before assembly, compare the color of the connector, the resistance of the coil and the marking with the disassembled element.
