• Description:

  This is the Genuine Ford 10R80 valve body separator plate for 18-23 F-150 applications. The separator plate is the precision metal layer that sits between the upper and lower halves of the valve body, with calibrated holes and orifices that meter ATF flow between the valves, accumulators, and clutch apply circuits. The plate determines a large portion of the calibration on the 10R80 because its orifice pattern controls shift feel, line pressure release rates, and clutch fill timing. A worn, washed-out, or wrong-spec separator plate is a documented source of harsh or flared shifts on these transmissions even after a valve body cleaning, because the metering edges no longer behave as the original calibration assumed. This Ford service plate is the correct part number for the JL3Z valve body and is supplied with the engineered gaskets where applicable. Install with new gaskets, the correct torque sequence on the valve body bolts, and clean ATF on all sealing faces. Complete the published adaptive learn routine after reinstallation so the controller resets its shift maps against the rebuilt valve body and separator pattern.
