Consequently, torque converter design is a very complex science where simple changes to the length, size, and shape of its internal blades and fins dramatically alter its performance characteristics.

So what purpose does a converter serve, and how does it work? “A torque converter is a fluid coupling that functions as a means of transferring power from the engine to the transmission.

ATI Performance Products shows you how to determine the stall speed needed and torque converter selection for your Chevy.

Rated torque converter stall speeds vary due to engine size, engine torque output characteristics, vehicle weight, camshaft, and other factors.

If this is the case, the electrically operated torque converter clutch solenoid is sticking, maintaining the differential pressure in the converter housing that keeps the clutch engaged.
