What Does a Torque Converter Do?
A car with a manual transmission has a special part known as the clutch. This connects the engine and the transmission. This connection is important, as it allows the vehicle to come to a full stop without killing the engine. To put things into perspective, without the clutch, the engine will have to be restarted every time you stop your car. On the other hand, cars with an automatic transmission have no clutch that separates the engine and the transmission.
Why does my transmission slip?
These slips happen if your car’s torque converter does not generate enough pressure to control the flow of the transmission fluid. Having too much or too little fluid in the transmission will mean that its gears will function in an unexpected manner. This isn’t always solely caused by a faulty converter, though.
Why is torque converter important?
When the engine is rotating at a faster rate compared to the transmission, the torque converter also acts as a torque multiplier. In this scenario, the torque is actually multiplied by at least two or three times the original amount. However, if the engine and transmission move at the same, or close to the same rate, there is actually a small amount of power wastage that occurs. This is the reason why manual transmission cars have better gas mileage when put up against their automatic counterparts that have torque converters installed.
What are the components of a torque converter?
It consists of four major components: the pump, turbine, stator, and transmission fluid. These parts all come in a highly durable housing that allows the entire mechanism to be connected to the car’s flywheel. This connection allows the torque converter to move at around the same speed as the engine does.
How much to replace a torque converter?
This may cost more money upfront, but it actually costs much less in the long run. A certified car mechanic would normally charge $600 to $1000, or a figure around that range, to replace a broken torque converter. While the part itself is relatively inexpensive compared to the price charged – around $150 to $300 – the labor adds a lot to the total. It can take anywhere between five to ten hours to replace a problematic torque converter because the entire assembly has to be taken out for that to happen. Replacing dirty fluids may or may not be included in your bill. This depends on which shop you go to get the needed repairs done.
