What is transmission flexplate?

A transmission flexplate is a component found in automatic transmissions that connects the engine to the transmission. It is a flat, circular plate made of steel or aluminum. It is attached to the engine's crankshaft and provides a mounting surface for the torque converter in the transmission. The flexplate is designed to bend slightly, or flex, in response to the engine's torque output and transmission load. This flexibility helps to absorb shock and vibration and allows for smooth shifting of gears. An improperly functioning flexplate can cause transmission damage, engine overheating, and drivability issues. Therefore, it is important to keep the flexplate well-maintained and replace it if necessary.
