What is a flex plate?

A flex plate, also known as a flexplate or flex disk, is a component in an automatic transmission system that connects the engine's crankshaft to the torque converter. It serves as a flexible coupling that allows the engine and transmission to smoothly transfer power and torque to each other.

Flex plates are typically made of steel or aluminum and are designed to withstand the high levels of torque and rotational forces generated by the engine. They are also balanced to ensure smooth operation and minimize vibrations.

In addition to transmitting power from the engine to the transmission, flex plates also help to absorb and dampen any sudden shocks or vibrations that may occur during gear changes or when the vehicle is in motion. This helps to protect the transmission and other drivetrain components from damage.

Flex plates should be inspected regularly for signs of wear or damage, such as cracks, warping, or missing teeth. If a flex plate fails, it can result in a loss of power transmission and may cause serious damage to the transmission or engine. In such cases, the flex plate should be replaced as soon as possible to ensure the continued reliability and safety of the vehicle.
