P2722 LUBRICATING FLOW SOLENOID VALVE

TRANSMISSION: GR6Z30A

P2722

Description


  • The lubricating flow solenoid valve is installed on the front control module and controls the lubricating flow of the clutches A and B with the signals from TCM. This subsequently controls the lubricating flow of the gear train.
  • The lubricating flow solenoid valve is a N/H type (normal high) in which control oil pressure is built up when no current flows through the coil.
