Keep your automatic transmission shifting on command with the Standard Ignition Automatic Transmission Control Solenoid (TCS116). It installs as a direct-fit replacement for the listed applications — the 2003-2008 Toyota Corolla and 2003-2008 Toyota Matrix (All engines).
A transmission control solenoid is an electro-hydraulic valve: it converts the electrical commands from the transmission control module into the movement that directs automatic transmission fluid through the valve body, controlling when and how the gears engage. When the original solenoid sticks or fails electrically, replacing it with TCS116 restores that fluid-flow control if the solenoid is the cause of the problem.
- Electro-hydraulic control: translates the control module's electrical signal into regulated transmission-fluid flow for shift engagement.
- Direct-fit design: made to install on the listed Corolla and Matrix applications.
- Serviceable replacement: a component-level fix for a solenoid that has failed rather than replacing the full valve body.
Signs the solenoid may need replacing include harsh, delayed, or erratic shifting and stored shift-solenoid trouble codes. Because these symptoms can have other causes, diagnose the fault before installing.
Manufacturer part number TCS116.
Frequently Asked Questions
What does this transmission control solenoid do?
It is an electro-hydraulic valve that converts the transmission control module's electrical signals into regulated fluid flow through the valve body, controlling how and when the gears engage.
Will the TCS116 fit my vehicle?
It is a direct-fit replacement for the 2003-2008 Toyota Corolla and 2003-2008 Toyota Matrix (All engines). Check the Buyer's Guide tab to confirm your exact vehicle.
What are the signs this solenoid may need replacing?
Common signs include harsh, delayed, or erratic shifting and stored shift-solenoid trouble codes. These symptoms can have other causes, so diagnose the fault first.
Is this the same as replacing the valve body?
No. This is a component-level solenoid that can be serviced on its own, rather than replacing the entire valve body assembly.
What is the part number?
The manufacturer part number is TCS116, from Standard Ignition.
