Help keep your automatic transmission shifting on command with the Standard Ignition Transmission Control Solenoid TCS123. It installs as a direct-fit replacement for the 2006-2015 Honda Civic and 2007-2013 Honda Fit, and its resistance and inductance are matched to OE. See the Buyer's Guide tab for engine-specific applications.
A transmission control solenoid is an electrically operated valve. When the vehicle's control module energizes it, the solenoid's pintle moves to block or vent fluid pressure, which helps direct hydraulic flow inside the transmission.
- Copper winding: 100% copper winding designed for positive valve actuation on command.
- Precision-ground pintle: moves freely to block or vent fluid pressure.
- OE-matched electrical specs: resistance and inductance matched to OE for proper fit, form and function.
- Stainless steel filter screen: helps keep contamination away from the valve components.
Signs this part may need replacing include harsh, delayed or erratic shifts, a stored transmission fault code, or a transmission that won't shift. These symptoms can have other causes, so diagnose the system before replacing the solenoid.
