Standard Ignition Automatic Transmission Control Solenoid P/N:TCS379
Help keep your automatic transmission shifting the way it should with the Standard Ignition Automatic Transmission Control Solenoid, part number TCS45. It is a direct-fit replacement for the listed applications, including the 1998-2005 Dodge Durango, 1994-1999 Jeep Grand Cherokee and 1996-1999 Dodge Dakota.
A transmission control solenoid is an electrically operated valve. When the vehicle's electronic control module energizes it, the solenoid regulates the flow of transmission fluid in the hydraulic circuit it serves. This helps govern how and when the transmission shifts.
Signs this part may need replacing: harsh, delayed or erratic shifts, a transmission that stays in one gear, or a check engine light with transmission-related codes. These symptoms can have other causes, so diagnose the system before replacing the solenoid.
