Standard Ignition Automatic Transmission Control Solenoid P/N:TCS40
Put precise, on-command valve action back into your transmission's hydraulics with the Standard Ignition Transmission Control Solenoid TCS179, designed to block or vent fluid pressure when it is signaled. It fits many vehicles, among them the 2013-2017 Honda Accord, 2016-2020 Honda Pilot and 2011-2017 Honda Odyssey, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list.
As an automatic transmission control solenoid, it works as an electrically operated valve. When the vehicle's control module energizes the coil, the pintle moves to route or release transmission fluid pressure that helps govern shifting.
Signs this solenoid may need replacing include harsh, delayed or erratic shifts, a transmission that seems stuck in one gear, or a warning light with stored transmission codes. These symptoms can have other causes, so diagnose the system before replacing the part.

Will this transmission control solenoid fit my Honda Accord?
Yes. TCS179 is listed as a direct-fit replacement for the 2013-2017 Honda Accord. The Buyer's Guide tab shows every listed application.
What does a transmission control solenoid do?
It is an electrically operated valve. When the control module energizes it, the pintle moves to block or vent transmission fluid pressure that helps govern shifting.
What are signs the transmission control solenoid may be failing?
Signs include harsh, delayed or erratic shifts, a transmission that seems stuck in one gear, or a warning light with transmission codes. Other faults can cause these too, so diagnose first.
How is the Standard Ignition TCS179 built?
It uses a 100% copper winding, a precision-ground pintle and a stainless steel filter screen. Its resistance and inductance are matched to OE.
How do I install this solenoid?
Procedures vary by vehicle, so follow the vehicle's service information. That includes the steps for checking the transmission fluid level after the repair.
