Lockup Solenoid
WARNING: This page is about a different car, the 2008 Subaru Tribeca, 2008 Subaru Outback, and 2008 Subaru Legacy. However, it is still accessible from the selected car via links, so may be relevant.
The lockup solenoid is mounted on the control valve and is directly controlled by electrical current instructions from the TCM. It then controls the lockup control valve to provide smooth engagement and disengagement. It also enables stable slip lockup control while supported by learning control and real time feedback functions.
