Solenoid Assembly
WARNING: This page is about a different car, the 2002 Dodge Intrepid, 2002 Chrysler Intrepid, 2002 Chrysler Concorde, and 2002 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
Solenoid assembly is controlled by PCM. PCM provides voltage to transmission control relay, causing contacts to close which supplies voltage to solenoid assembly. Solenoid assembly controls transaxle hydraulic circuits. PCM completes ground circuit, operating solenoid for proper hydraulic circuit control. Solenoid assembly may be referred to as solenoid pack.
