In automatic transmission vehicles, the torque converter plays an important function. If you want a beautiful and smooth ride, it must be in good functioning order. You're in big trouble if it doesn't work.

The torque converter is a fluid or hydraulic connection that transfers the rotational power generated by the rotating driving force of the vehicle into mechanical power.

In automatic transmission vehicles, the torque converter replaces the mechanical clutch disc, plate, and fork. The torque converter is normally located between the engine flex-plate and the transmission.

You will understand the many sections of the torque converter and the symptoms of a faulty torque converter. You'll be able to determine the difference between a faulty torque converter and a bad transmission.

Before booking you next MOT testing service , ensure that any issues relating to the torque converter are fixed as this ...
... could result in a MOT failure. The main reason for this is that it will prevent the MOT tester in checking the compulsory sections in a MOT test.

Parts for Torque Converters
Every automatic gearbox vehicle's torque converter is made up of four pieces:

1. Stator
The stator is the torque converter's reel conductor. It is the torque converter's brain. The stator controls the flow of fluid within the converter and is responsible for torque amplification. A one-way clutch within the converter helps the fluid go through the converter.

2. Impeller pump
When working on an industrial torque converter, the impeller pump should be the first item to look at. An impeller pump, comparable to a centrifugal pump, is used in the torque converter. Like the centrifugal pump, the impeller pump is designed to circulate fluid in a rotating pattern. The vacuum created by the impeller pump draws fluid into the centre of the pump, which circulates it through the converters outside the wall before expelling it.

3. Turbine
The impeller pump's ejected fluid enters the turbine's blades. The turbine is attached to the gearbox's internal components, spins the transmission, and drives the wheels.

4. Clutch
In high gears, the clutch is utilised to lock up the gearbox and prevent it from sliding. In a contemporary clutch converter, the clutch is frequently found. Friction clutches are the most common name for them.

Although the transmission fluid is not part of the torque converter, it plays an important role in hydraulic coupling, great starts, and preventing the engine from stalling when the gears are disengaged. When the torque converter breaks, you don't have to worry about rebuilding or replacing the complete automatic gearbox. You can rebuild or replace the torque converter as a single item because it is self-contained.

Ensure that you stick with the manufactures recommendations when it comes to gearbox/transmission service. Simply search online for garages in Reading and book your car in with a professional car mechanic.

The Signs and Symptoms of a Faulty Torque Converter
Transmission difficulties are sometimes misconstrued as issues with a malfunctioning or faulty torque converter. As a result, vehicle owners will be forced to pay thousands of pounds to replace or rebuild their transmissions. They may be unaware that the problem is with their torque converter, which is separate from the transmission.

Let's take a brief look at the signs of a malfunctioning torque converter:

1. Gear change issues
If your gear changes are mushy or delayed, you most likely have a bad torque converter. This is mostly due to a reduction in pressure production. You will have a rough and odd gear change instead of a pleasant and precise transmission change. Increasing the torque converter output pressure by increasing the engine RPM is the greatest technique to attain that sharp and pleasant gear.

2. Car speed issues
If the torque converter output pressure is irregular, the torque converter may suddenly raise or reduce the vehicle speed. Because of the fluctuating fluid pressure, the throttle will begin to fail at that point. It may be risky to drive your car if this occurs, so don't do so until you've fixed it. You may feel a shiver, but don't forget to call your professional car mechanic to have the gearbox mounts inspected and tightened if they are loose before evaluating the torque converter.

3. Shuddering
If your vehicle rattles or shakes when travelling at 30 to 45 mph, it's likely that your torque converter is malfunctioning. The vibration may resemble that of driving on a rough road, making it easy to detect. The trembling sensation will not be constant. It frequently occurs and then vanishes. Once you detect it for the first time, you should contact your technician to get it inspected.

4. Transmission slippage
A faulty torque converter will quickly reveal itself due to its inability to correctly regulate fluid. It will either put too much or not enough fluid into the transmission, resulting in gear slippage and sluggish acceleration. There will also be a reduction in fuel economy. It's possible that the transmission fluid will be reduced as well. When you observe transmission slippage, you should always check your transmission fluid.

5. Unusual noises
Every vehicle makes some form of noise, whether it's whining or rattling. If you listen to the car sounds while driving for a long time, you should be able to determine when something is wrong. When a vehicle torque converter malfunctions, the vehicle makes a poor torque converter noise-a whining or wailing sound that sounds like a power steering pump with little or no fluid. When the clutch mechanism in the torque converter breaks, you'll hear a whining or rattling noise that may or may not be audible when the car is parked. When you engage the gearbox gears, the whining sounds becomes louder, indicating torque converter difficulties. What causes a torque converter to fail, you might wonder? Many things can cause a torque converter to fail. Excessive friction, which can be produced by a broken torque converter needle bearing, can cause torque converter failure. A bad clutch solenoid and faulty seals might also be to blame.

6. Overheating
Some vehicles include a transmission temperature indicator that alerts the driver if the transmission is overheating. When the temperature of the vehicle gearbox rises over the ideal working temperature, you may notice that your vehicle begins to perform strangely, or even goes into fall date, with hard gear changing or no gear changing at all. When two problems occur at the same time, it's possible that something is wrong with your torque converter. A gearbox overheat appears to suggest that the torque converter is unable to adequately transmit power from the engine to the transmission.

7. Contaminated transmission fluid
As a hydraulic and fluid coupler, the torque converter will not function correctly if the transmission fluid is contaminated. Let's say the transmission fluid is tainted. Everything that uses the fluid will be impacted to some degree. If your transmission fluid is polluted and you have any of the symptoms listed above, you most likely have a malfunctioning or bad torque converter.

8. Fluid leaks
If you see fluid flowing from between the transmission and the engine, it's possible that the torque converter seals have been broken. The torque converter seals can be harmed by a variety of circumstances, causing them to leak. Fluid leaks indicate that the torque converter isn't keeping the proper quantity of transmission to transmit power from the engine to the gearbox. In the long run, this will harm the transmission and the engine.

If the torque converter fails, the car engine must perform more tasks in order to maintain the same engine speed. The engine will need more revolutions per minute to run, lowering fuel economy and fluid pressure. In the worst-case situation, the system will generate more heat, causing problems with other components. As mentioned earlier, this can result in an MOT test failure, so it is recommended to check MOT status of your vehicle and have this issue fixed.
