What is a torque converter stall speed?

Stall speed is the RPM at which the torque converter will lock up and transfer power directly from the engine to the transmission. A 3000 RPM stall speed means the engine can rev to 3000 RPM before the converter fully engages, allowing for a stronger launch off the line.

What does 'billet' mean in this context?

Billet refers to a solid block of metal that is machined to create the part. In this case, the front cover and lockup piston are machined from solid billet aluminum, making them much stronger and more durable than cast components.

What transmissions does this torque converter work with?

This FTI Performance torque converter is specifically built for use with the 4L80E and 4L85E automatic transmissions. It is not compatible with other transmission models.
