this is the most recent version of starting clutch piston to be used with multiple spring retainer.
we know about three different pistons for the starting clutch in this transmission. Please check our information data sheet "IDS-SWRA-Starting clutch piston" and "IDS-SWRA-starting clutch" for further details.
complete current and previous starting clutches are interchangeable, but components are not interchangeable. Also the secondary drive gear can be different - with our without oil feed holes.
