What is a Lock-Up Torque Converter?

The torque converter, like its name implies, can transmit and multiply engine power. It is known as a type of fluid coupling or hydraulic coupling, though a torque converter uses much more power than a regular fluid coupling. A fluid coupling is a device that is created to transmit rotating mechanical power. Torque converters work alongside the engine by transferring the rotation power that is produced by the engine.

Automatic transmissions rely on the torque converter to supply the load with power, and manual transmissions rely on the clutch. Torque converters are considered a mechanical clutch alternative. The location of the torque converter is between the transmission gears and the engine.

Lock-Up vs Non-Lock-Up Torque Converter

A lock-up torque converter is the modern-day torque converter. It is created with a built-in locking clutch mechanism. The lock-in torque converter uses the clutch to lock up a connection between the output and input shafts. This helps to maximize efficiency.   

Non-lock-up torque converters were used in the past before the invention of the lock-up torque converter. They would experience slippage that resulted in energy loss during the transfer of power between the transmission and engine. The lock-up torque converter was invented to maximize efficiency to prevent energy loss due to slippage.
