FAQ

Frequently Asked Questions

No. The torque converter is a key component within an automatic transmission, acting as the fluid coupling between the engine and the gearbox.

It depends on the failure. Some internal parts can be serviced or replaced in a rebuild, but severe damage often requires a complete unit replacement.

Typically, no. Electric motors provide maximum torque from zero RPM and don't need to idle, so they usually use a simple single-speed reduction gear or direct drive, eliminating the need for a torque converter.

It means a internal clutch mechanically locks the turbine to the impeller, creating a direct 1:1 drive connection to eliminate fluid coupling slippage, improving efficiency at highway speeds.

A fluid coupling in an automatic transmission that transfers rotating power from the engine to the transmission, allowing the vehicle to stop without stalling.
