What is a lock-up torque converter and why is it beneficial?

A lock-up torque converter has a clutch that mechanically connects the engine to the transmission at cruising speeds. This reduces slippage, which can improve fuel economy and lower transmission temperatures on the highway compared to non-lock-up converters.

What is the stall speed, and how does it affect performance?

The stall speed, rated here at 2800 RPM, is the engine speed at which the torque converter can effectively transfer power. A higher stall speed like this one is generally better for performance driving, allowing the engine to rev higher before the converter fully engages, leading to quicker acceleration off the line.

What transmissions does this converter fit?

This FTI torque converter is specifically designed for early 700R4 and 4L60 transmissions. It's important to verify your transmission model, as later versions or different transmission types may require a different converter.
