This is a remand converter that is ready to go. Dyno tested leak checked new clutches and all the billet parts that makes a revmax special. This Is a 1500 dollar converter plus core. I am wanting 800 plus shipping no core. I build for a living so when say you can run this in a 48 with out the sealing ring on the stator I know it can be done as do it often. Not recommend on stock ones but these triple disk hit so hard when locking it won't hurt to have that ring off on a 48 and run it just as the 47re uses it so can go either way or an older 618.
