A correctly functioning torque converter is a requirement for a smooth operation of a cars transmission. If there is a problem creating a malfunction then there are some symptoms that your car will show. Here, you will get a short idea of what a torque converter is and some of the most common ways to know if yours is going bad. Keep in mind that other issue with your vehicle might show these same signs, so it’s important to check for more than one of these symptoms to confirm that the cause lies with the torque converter.
Torque Converter; what is it?
In an automatic engine, a torque converter is a component that takes the place of a manual clutch, making the engine to move somewhat independently of the transmission. This is what makes the engine to idle instead of cut off when the wheels and transmission stop, such as when you halt at a traffic light.
The housing of a torque converter, which links to the flywheel, has three parts: the pump, turbine, and stator. If any one of these parts isn’t working correctly, the flow of your transmission fluid will be compromised and many other problems will follow.
1. THE GEARS IN YOUR TRANSMISSION WILL SLIP
If the gears in your vehicle’s transmission are slipping, then you might have an issue with the converter. If there isn’t sufficient pressure to control the flow of the hydraulic transmission fluid, too much or too little will find its way into the transmission and cause the gears to slip during shifting. This can often be due to low or bad fluid as well, so be sure to confirm that first.
2. YOUR VEHICLE DOESN’T ACCELERATE PROPERLY
With gear slipping, you may also experience a loss of acceleration. This is due to the fact that a torque converter controls hydraulics, and if it’s bad, it won’t allow sufficient pressure to go to the transmission and this causes the car to accelerate poorly.
3. YOUR VEHICLE DOESN’T SHIFT GEARS EASILY
Similar to gear slippage, if the flow of your transmission fluid is bad, you might have a hard time shifting gears at all. The transmission might even strain as it shifts.
4. SURGING OR LAGGING TRANSMISSION
Again, due to a bad torque converter means that your flow of transmission fluid isn’t what it should be, you can also have issues will transmission surges or lags when driving. This will be especially seen at times when you’re maintaining a consistent speed.
5. CAR SHUDDERS
When you drive at a lower speed, around 30 to 45 miles per hour, you may feel a shudder, as if you’re driving over bumps. One thing that could cause this is a bad torque converter.
6. DIRTY FLUID
Check the transmission fluid. If there are a lot of black flecks in it, your torque converter clutches could be the issue. Drain the fluid and replace it once you have addressed the problem to make sure there isn’t another cause.
