What is a torque converter lockup?

In a vehicle with an automatic transmission, the torque converter connects the power source to the load. Some of these devices are also equipped with a "lockup" mechanism which rigidly binds the engine to the transmission when their speeds are nearly equal, to avoid slippage and a resulting loss of efficiency.

People also ask, how do I know if my torque converter is locking up?

You can see this by looking at the RPM's, once moving at steady speed give the car a little gas, you will see the RPM's rise but the car will not speed up much. When a lock up torque converter locks the and you give it a little gas the RPM's will not rise until the car starts moving faster.

Additionally, do torque converters need a lockup? If you are going to be towing, you want a lock-up torque converter. Towing will add heat to the transmission. A non-lock-up torque converter will add more heat. With a lock-up when you get to speed, the torque converter will lock-up, which creates a direct drive from engine to transmission.

One may also ask, how does a lockup torque converter work?

The innovative lock up system connects the impeller with the turbine, transforming the torque converter into an absolute mechanical coupling. The result of an implanted lock up mechanism includes improvement in gliding transmission power and less waste heat.

How do I test my torque converter?

Testing for Bad Torque Converters Turn the ignition key and start up the engine. Wait for a few minutes for the engine to warm up, then gently press the accelerator twice and rev up the engine. Once it returns to its idle state, press the brake pedal all the way and shift into drive.
