How to Unplug the TCC Solenoid

This blog is effortless, though it is not easy to use a unplug tcc solenoid. Below we have analyzed in brief how to clear the tcc solenoid. You should know how to open the tcc solenoid works before using it. Sometimes it’s the case that you have to do an emergency repair. A coming step is to learn how to get to the unplug tcc solenoid. No matter where your vehicle is, you have a good chance.

How to Unplug the TCC Solenoid

A Step By Step Guide to Unplugging TCC Solenoid:

If you are talking about the TCC solenoid, you should use the following instructions: 

  • Remove the air cleaner lid and disconnect the battery. It does use to prevent the engine’s accidental activation during the next steps.
  • Remove the cabin air filter box and unbolt the TCC Solenoid. 
  • Gently pull the TCC Solenoid up and out of the way. 
  • To remove away any dirt, use a rag that might be in the TCC Solenoid bracket or the vacuum line. 
  • Use an electronic tester or a multimeter to test the vacuum hoses attached to the TCC Solenoid. 

If the multimeter indicates a vacuum leak, use the list below to determine which vacuum line leaks. It was not a contributing vacuum line to the TCC Solenoid failure if it’s not listed here. 

  • Vacuum hose manifold to the TCC Solenoid. 
  • from the engine air cleaner box to the TCC Solenoid. 
  • Vacuum hose from the TCC Solenoid to the transmission. 
  • The vacuum hoses connected to the TCC Solenoid are vacuum hoses C and D.

Some Other Ways to Unplug TCC Solenoid

How to Unplug the TCC Solenoid

Way 1

The best way to unplug the tcc solenoid is to use a Scan tool. With a scan tool, you will check the codes and reset the codes to check the tcc solenoid for a diagnosis. The best way to unplug the tcc solenoid is to have the proper tools to open the tcc solenoid for a better look. If the tcc solenoid is misfiring in a specific scenario, you can have the ability to unplug the tcc solenoid to find out what is going on.

Way 2

When you’re ready to remove the tcc solenoid, remove the four bolts that hold the tcc solenoid onto the engine. You can pull it without carrying off any additional elements.

Then, you can rotate the spindle until you find the Solenoid. You can use a flathead screwdriver. It is to pry the Solenoid up and off the engine. Behind that, you can substitute it with a unique one when you have a period.

Way 3

You can use a jumper wire (a wire with a stripped end used to connect two wires). The jumper wire should be thin enough to fit between the two pins on the TCC solenoid. You can try the following: 

  • Unplug the connector and ignition from the TCC solenoid. 
  • Tape the jumper wire’s end to the connector wire’s back for the TCC solenoid. 
  • Stick the tape end of the jumper wire into the hole on the Solenoid and turn on the ignition. 

· Rotate the steering wheel toward the poor TCC solenoid. 

  • Plugin the connector to the TCC solenoid and depend on the ignition. Keep turning the steering wheel until the TCC solenoid is closed. It should unplug the TCC solenoid.

Way 4

The best way to unplug the tcc Solenoid is to check the service manual to identify the Solenoid and its function. Then, check the wiring harness and the connectors. Inspect the electrical terminals of the Solenoid. If the Solenoid is harmed, convert it with a fresh one and your vehicle does equip with a snap-type connector, follow the pry bar method: insert a pry bar into the connector and push it into the Solenoid terminal. If your vehicle will equip with quick-disconnect terminals, follow the push-in procedure: go the connector onto the Solenoid terminal.

Way 5

You have to open the solenoid holder case and remove the Solenoid springs. After that, you have to pull the Solenoid off the base carefully. You have to remove the compression springs to change the valves to loosen the screws that are near the valve and then remove the valve, and then you have to remove the isinglass seat. You have to slide the new valves inside the Solenoid and then put the Solenoid back in the holder case to maintain accomplish the overhead stages in the reverse directive.

Frequently Asked Questions

What Happens When The TCC Solenoid Goes Bad?

If the Throttle Control Cable (TCC) solenoid goes wrong, there’s no way for the computer to tell the throttle body to open up. The car will run with a lean air-fuel mixture around 25% rich if this happens. It will induce misfires acceleration issues.

Do You Drive With A Bad TCC Solenoid?

No, you may not go with a poor TCC solenoid. The traction control system relies on the servo pressure from the TCC solenoid to provide stability for vehicle movement in inclement conditions. Without the TCC solenoid, there is no servo pressure, and strength cannot offer.

What Does A TCC Solenoid Do?

A TCC solenoid is an electromagnetic device that controls the transmission clutch on vehicles with manual transmissions. Without it, the gears would grind together and eventually break or strip. Transmission clutches are necessary for cars to move smoothly, significantly when accelerating from a stop.

Is There A Fuse For TCC Solenoid?

The Solenoid for the transmission control system is not directly fusible but instead does monitor by the Electronic Control Module (ECM), which can detect an under-voltage condition. If the Solenoid fails, the ECM will turn off the TCC and lock out the problem.


The communication management solenoid (TCC) valve regulates liquid discharge in an automatic transmission. When the TCC valve is engaged, the information is in “drive,” The vehicle can shift without pressing the accelerator. When the TCC valve is disengaged, the transmission is in “neutral,” The car can change by pressing the accelerator pedal. We hope that you have gained some new knowledge from this post.
