Keep your automatic transmission shifting on command with the Standard Ignition Automatic Transmission Control Solenoid (TCS105). This electro-hydraulic solenoid controls the flow of transmission fluid through the valve body so the transmission can engage the commanded gear. It installs as a direct-fit replacement for the listed applications, including the 2005-2006 Scion tC, 2002-2005 Toyota Camry, 2000-2005 Toyota Celica, 2003-2004 Toyota Corolla, 2001-2007 Toyota Highlander, 2003-2004 Toyota Matrix, 2001-2005 Toyota RAV4 and 2002-2005 Toyota Solara.
- Function: Uses an electric coil to open and close a hydraulic passage, directing transmission fluid to control shift timing and engagement.
- Signs it may need replacing: Harsh, delayed or erratic shifts, failure to shift, or a stored transmission fault code — diagnose the cause first, since these symptoms can have other sources.
- Direct fit: Designed to replace the original solenoid on the listed applications.
If a failed control solenoid is the cause of your shifting trouble, this unit replaces it. See the Buyer's Guide tab to confirm the exact fit for your vehicle.
