Flex or Drive Plate


Drive plates or Flex are used by automatic transmission vehicles. This component is a meta disc which connects transmission’s torque converter to the engine’s crankshaft. The flex plate has a ring gear at the circumference to mate with the starter motor of the engine. With such direct connection, the plate delivers power to the transmission. The plate can be reused if it is in a great condition and the teeth aren’t worn out, but flex plate replacement is one of the most challenging jobs for the mechanics. The clear indication of flex or drive plate repair & replacement are knocking or rattling noise from rear of engine or abnormal noise when operating engine starter. As the flex or drive plate connects the engine to the automatic transmission, Universal Motors recommends that a broken flex plate is a problem which the car owners should not ignore.

The most common reason is the misaligned gears between the engine and automatic transmission, which cause the flex plates to bend and crack. The flex plate can also break due to excessive crankshaft lange run-out. Under whatever circumstances, broken or damaged flex plates should be replaced immediately to prevent potential accidents on the road.
