Flexplate is an important part of the Powertrain in Automatic Transmission Vehicles. It acts as a coupling between Engine & Transmission and connects the output of engine to the input of a torque converter for transmitting power from Engine to Transmission. It also acts as dampener & avoid transfer of vibrations from Engine to Transmission. Flexplate along with Torque converter takes the place of the flywheel & clutch assembly, which is typically found in a conventional manual transmission setup.
