How does a torque converter work

The correct direction, in this case, is the same as the direction of the pump. Those were the three major parts that make the torque converter work. A flywheel from the engine is connected to the casing of the torque converter. This makes the entire casing rotate at the same RPM as the engine. The pump is connected to the casing and thus rotate with the same rpm and direction. There is fluid present inside the casing which is thrown around by the pump using centrifugal force.

This fluid then goes towards the turbine which has small grates in it. These grates allow the fluid to go in and move the turbine. The turbine absorbs the torque and starts to rotate. The turbine is connected directly to the output shaft. After the fluid comes out of the turbine it has almost no momentum left and is in the wrong direction of what the pump wants it to be. Hence the stator is used. It rotates the direction of the fluid and makes it similar to what the pump requires. This concludes the cycle which keeps on rotating to move the car.

The torque converter does it all by itself thus making it truly automatic. So without a clutch, when slowing down to a stop, an engine would stall as the load from the transmission would drag it below its workable rev limit.

The clutch allows the disconnection required to keep the engine running and then the re-engagement along with some throttle to get the car up and running again. It needs to do the same job as a clutch — allowing the engine to stay running while the transmission and wheels slow down to a stop — but it goes about it in a different and rather ingenious way.

It can replace a clutch due to the fact that it allows the engine to rotate freely by vastly reducing the torque delivery from the powertrain to the transmission. The torque control is achieved through the use of a pump that sends fluid around the torque converter depending on the rotation of the crankshaft. The casing of the torque converter is connected to the flywheel which therefore spins at the same rate as the crankshaft and within the housing is the turbine, the fluid centrifugal pump or impeller and a stator.

The centrifugal pump effectively flings the transmission fluid into the fins of the turbine which in turn spins and transmits torque through to the transmission.

The stator is there as a barrier to fling fluid straight back to the turbine instead of back to the pump, vastly increasing the efficiency of the system. Most owners will never interact with this part in their entire driving life. Getting to know about its working could help you know how to diagnose problems attributed to your transmission, saving on time and cost of repairs.

Thank you. Came in with a transmission U And.

Came in with a transmission issue, fixed the problem and advised along the way as to what is happening, what went wrong etc, no one does that love their customer service and they really know what they doExtremely recommend.

Great service friendly and efficient. Bonnie Hall. Great service, they fixed my Dave Porter. Great service, they fixed my car very quickly and for a great price. Very professional. Highly recommend! After visiting a few other Becky Mclennan. After visiting a few other shops I went to Mister Transmission for the free diagnosis and wow am I glad I did.

The other shops I went to quoted me several thousand dollars for the repair I needed. Dave was great to deal with and was able to fix my car for significantly cheaper than the other shops.

If you have car issues I highly recommend this location. Customer service was fantastic and David Ellis. Customer service was fantastic and they were very efficient. Thanks to this very knowledgeable team for your help! Kyle is fkn great, give Joshua Creasey. Kyle is fkn great, give him a raise.

Blew my clutch line and brought it in and he fixed my beater like it was a mercedes.
