What does a torque converter clutch do on a Honda Accord?
It means that the Accord ‘s computer has detected that there is an issue with the torque converter clutch (TCC) solenoid circuit. The TCC “locks” the drivetrain, which allows for a true mechanical connection between the transmission and the engine.
Is there a problem with the torque converter?
It could be a problem with the transmission, or the transmission could be perfectly fine and it could be a problem with the torque converter. Torque converter issues on a lot of older transmissions can be diagnosed by carrying out a stall-speed test.
What causes a shudder in the torque converter?
Shudder in the Torque – You’ll know this is happening if the engine block shakes or quivers even at a slight acceleration, and even on smooth surfaces. The cause of this issue is a torque converter failing to effectively distribute power for the transmission.
Why does my torque converter make a whirring sound?
Whirring sound when starting up the engine – When the one-way clutch within the torque converter wears, it starts making a whirring sound. But this sound could also be caused by the formation of vacuum bubbles in the fluid as the pump fails.
Where is the torque converter on a car?
The torque converter, in layman terms, is designed to transfer the power from the engine to the transmission. Installed and mounted on what’s known as a flex plate, which is located in between the engine and transmission, the crankshaft will spin this plate, creating the conversion effect.
Why is my torque converter not working properly?
If your temperature gauge starts to rise, it can be due to a multitude of reasons, but in some cases, it could be due to the torque converter since a drop in fluid pressure can cause this part to overheat, and because of this, the part is no longer able to transfer power from the engine to the transmission.
How much does it cost to repair torque converter on Toyota Tundra?
Toyota Tundra. $875. Since this a labor-intensive job, the costs can be quite high, even though the part doesn’t cost (about $85 to $175) that much since a mechanic will have to remove the transmission to inspect and repair the part as this part is sandwiched between the transmission and the engine.
Why does my torque converter make a rattling noise?
As the assembly contains a part with a lot of clutches, when it goes bad, a rattling noise can be heard, even while the vehicle is in park. As you put the transmission into gear, the noise will increase, which often points to the torque converter as the problem at hand.
What is the code for torque converter clutch solenoid?
Code P0740 indicates that the control module detects an electrical problem with the torque converter clutch solenoid or the solenoid’s circuit. Note: Although code P0740 is a generic code specified by the Society of Automotive Engineers (SAE), the code’s definition may vary depending on the vehicle manufacturer.
When does the torque converter clutch turn off?
The torque converter clutch is supposed disengage when you step on the brake pedal. It’s also supposed to turn off when the transmission begins to downshift or when the vehicle is moving below 25 mph. When people would complain about torque converter clutch problems and the 125C was installed we ran a quick test.
How does the transmission work on a Honda Accord?
The Accord uses a clutch in the torque converter to lock the engine and transmission together at highway speed. P0741 can register whenever this connection is not happening at all or happening properly.
It means that the Accord ‘s computer has detected that there is an issue with the torque converter clutch (TCC) solenoid circuit. The TCC “locks” the drivetrain, which allows for a true mechanical connection between the transmission and the engine.

What to do if your torque converter clutch is faulty?
If there is an open circuit at the transmission plug or a value far outside of the specs, you need to remove the transmission pan and locate the clutch solenoid. Measure the same on the solenoid when you found the transmission clutch solenoid. Replace if faulty.
What causes a torque converter clutch code p0740?
To fix the P0740 code, you need to diagnose a faulty converter clutch solenoid or a wiring issue causing the problem. To do so, you can follow our diagnosis guide in this article. What causes code P0740?
How to test the torque converter clutch ( TCC )?
Measure the resistance between torque converter clutch (TCC) solenoid pins #1 and #2 ( see the illustration in the image viewer ). Your multimeter should register 12-25 Ohms if the torque converter clutch (TCC) solenoid is within specification. Let’s take a look at your test results:
What happens if the torque converter goes bad?
It is highly likely that the torque converter clutch solenoid (TCC) has gone bad. But, jumping straight to this conclusion without inspecting the transmission fluid and wiring can cause a lot of undue headache. The torque converter itself or torque converter clutch can go bad and throw the P0740 code.
How to test the TCC solenoid on a Honda Civic?
In this tutorial I’m gonna’ show you how to test your 2001-2005 1.7L Honda Civic’s torque converter clutch (TCC) solenoid. The TCC solenoid diagnostic involves to specific tests. The first is a simple resistance test of the TCC solenoid’s internal coil.
It is highly likely that the torque converter clutch solenoid (TCC) has gone bad. But, jumping straight to this conclusion without inspecting the transmission fluid and wiring can cause a lot of undue headache. The torque converter itself or torque converter clutch can go bad and throw the P0740 code.
What are the torque specs on a Honda Civic?
This article applies to the Honda Civic (incl. Del Sol) (1992-2000). Tightening your bolts too much or not enough can cause a part to fail, and depending on the part, can put your life and the lives of the any passengers in danger. Most parts come with bolt-tightening torque specs, and your owner’s manual should have this information too.
