Standard Ignition Automatic Transmission Control Solenoid P/N:TCS40
Put transmission fluid pressure back under precise electrical command with the Standard Transmission Control Solenoid TCS108. It is a direct-fit replacement for many vehicles, among them the 2011-2016 Ram 1500, 2004-2010 Dodge Ram 1500 and 2011-2016 Ram 2500. See the Buyer's Guide tab for the full list and engine details.
This automatic transmission control solenoid is an electrically operated valve. When the transmission control system energizes it, the internal pintle moves to block or vent fluid pressure in the transmission's hydraulic circuit.
Standard is a global manufacturer that maintains quality control across its entire production process.
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 cause before replacing the solenoid.
