Standard Ignition Automatic Transmission Control Solenoid P/N:TCS40
Standard Motor Products
Standard Ignition TCS179 transmission control solenoid for the 2013-2017 Honda Accord and other vehicles blocks or vents fluid pressure inside the transmission on command. Also called an automatic transmission control solenoid, it sits inside the transmission and bolts on.
Harsh, delayed or erratic shifts and a transmission warning light can be signs of a worn solenoid. These signs alone do not prove the solenoid is the problem; a damaged wire harness can cause them too. The transmission takes a single solenoid, and this listing is one.
The 2013-2017 Honda Accord, 2016-2020 Honda Pilot and 2011-2017 Honda Odyssey are among the vehicles it fits. Its resistance and inductance are matched to OE for proper fit, form and function.
