Sonnax has introduced a Zip Kit (#6R80L-6R100-ZIP) that targets the root cause of multiple complaints by sealing the critical circuit pressure losses in the Ford 6R100 and 2015-later 6R80 valve bodies. The kit contains uniquely designed parts to prevent the loss of pressures within the main line, solenoid regulator, reverse, clutch control, and solenoid apply circuits. Installation is quick and easy with no special tools required.
