What Does A Torque Converter Clutch Solenoid Do?

The torque converter clutch solenoid is positioned between the back of the engine and the front of the transmission but What Does A Torque Converter Clutch Solenoid Do? What is the purpose of torque converter clutch solenoid?

The torque converter clutch solenoid controls the behavior of the engine in different driving problems. The converter is responsible for transmitting the engine’s force and power to the transmission.

To stop Slippy at bound speeds (normally speeds exceeding 37 mph) a lockup clutch settled within the convertor locks the engine’s output drive to the transmission’s input shaft to attain a 1:1 ratio which means 100 percent of the engine’s power is currently reaching the transmission.

The fluid pressure that applies and releases the torque converter lockup clutch is controlled by the converter clutch magnet.  The opening and closing of the TCC magnet valve are controlled by the transmission management module (TCM) or powertrain control module (PCM), depending on the vehicle.

Torque Converter Clutch Solenoid Do

Engine Speed

A car’s torque converter magnet could be a hydraulic coupling between the engine and transmission. It activates once a vehicle moves forward from a complete stop. This movement puts a lot of pressure on the fluid than at idle or low speeds. The magnet regulates this pressure to take care of a relentless engine speed.

The magnet closes the connection to the engine and engages or disengages the transmission clutch. An indication from the engine management module that controls the magnet. once commanded to interact, it sends out an electrical current.

The current actuates 2 magnetic coils that are settled within the magnet switch. The field created by these coils pulls on ferrite cores, which push on a grounded plunger that opens the contacts within the switch.

Advantages Of TCC Solenoid

The major advantage of the converter clutch solenoid is that it permits a smoother acceleration and retardation method. the first function of the TCC magnet is to lock up the converter once an engine’s RPMs exceed a particular level. This technique stops the transmission from over-revving. Moreover, it improves fuel potency by lowering power lost once the transmission spins up and down.

Saving On Prices

You tend to avoid wasting on repair prices because the magnet could be an element that stops engine slippage. Slippage happens once the gears within the transmission slip and grind against one another. This produces plenty of noise and wear. The TCC solenoid perpetually lubricates the gears within the transmission to stay them from grinding against each other.

This considerably reduces repair prices for your vehicle. The engine’s force is limited when in use, therefore preventing it from spinning and sporting out. It can control the shifts in your vehicle. there’s hardly any slippage once the TCC is locked. The components within the transmission have reduced friction, meaning less wear and tear.

Fuel Efficiency

The convertor clutch magnet will increase fuel potency. you’ll decrease fuel consumption by engaging the convertor once the engine is running. It will increase fuel potency by creating it attainable to slide the clutch with less effort. Engage the clutch only if required, because it reduces wear and tears on the engine.

A Slippy clutch makes the engine idle at an identical time because it is popping, which saves fuel by reducing friction. The torque mechanism reduces the quantity of energy required to start, stop, and coast. This ends up in shorter periods of your time wherever the engine must run at high speeds, which saves gas by decreasing the frequency of gap and shutting valves.

Reduces Clutch And Transmission Wear And Tear

A car’s TCC solenoid is sort of a small switch that automatically turns the clutch on and off. The magnet will do this by causing an electrical current to the clutch, that controls engagement. Once there’s no power, the clutch can disengage. Once the magnet gets power, the clutch can interact and keep in place as long as the magnet has power.

The TCC solenoid works in conjunction with the transmission. It engages a rubber diaphragm once the magnet is activated. This cuts off the flow of fluid to the clutch so that there’s no slippage. Hence, it reduces the damage and tears on the clutch and transmission. once no gears are Slippy, no components are moving with further force.

Prevents Stalling In Heavy Traffic

A car’s converter solenoid helps stop stalls in significant traffic by controlling the fluid within the transmission. The position of the magnet is in a very position that will regulate pressure once it’s operating. So, in stop-and-go traffic, it’ll get ready to keep automotive from stalling out

The convertor magnet responds to the vehicle’s speed and throttle position. It prevents the vehicle from stalling once idle if the accelerator is engaged. The magnet starts by eliminating low-speed creep so that the vehicle won’t stall while loading. It conjointly calibrates the idle speed of the engine to permit smooth acceleration under heavier masses.

Allows For Smoother Shifts

A car’s converter clutch magnet permits for sander shifts by electronically dominating the clutches. The control permits it to match the engine and transmission speeds. This makes it easier to travel from one gear to a different one as a result it lessens the jarring feeling which will happen once you shift gears manually.

It permits smoother shifts by sensing once the engine speed is just too high. Then it disengages the clutch from the regulator. This not solely prevents more injury to the transmission however conjointly reduces the strain on the engine. The solenoid reengages the clutch once the engine speed decreases.

Improved Performance With Clutch Solenoid

The magnet improves performance by disengaging the clutch for a definite period. Thus, fuel economy and performance increase. It engages the clutch quickly to permit you to modify gears while not having to abate. You oughtn’t to use any force that might harm the transmission.


Now we know what is the function of a torque converter clutch in the car or What Does A Torque Converter Clutch Solenoid Do? But sometimes it can stop working or start working improperly so simply you should visit mechanic he will fix it.

Frequently Asked Questions

How will a defective torque converter clutch coil cause the vehicle to stall once the vehicle is fastness to a stop?

When the solenoid is open, the engine is locked to the transmission thus there’s no transmission slip. With the transmission unable to slide, the engine can stall once the vehicle involves a stop. this sort of coil failure can set a Diagnostic trouble Code inflicting the Check Engine light to illuminate.

What happens once the converter goes bad?

A bad converter will harm a transmission. dangerous force converters will result in harm, warming, friction, and transmission fluid degradation. If these issues continue, it will cause even a lot of harm to transmission.

Can you drive with a bad converter clutch solenoid?

It will effectively damage other engine components and find pricey on your car’s transmission. However, you’ll drive an automobile even though you’ve got a lousy converter coil. As long as the shift coil doesn’t shift on the far side of a selected gear, you’re good to travel.
