For the most part they shift faster and hold tighter. That is stock for stock. With all the upgrades available you can upgrade them to anything you want. As Dnmfranco said, It has an extra clutch plate in the clutch packs. It also has a better valve body with quicker shifts, special apply pistons to dump oil out of the clutch pack faster, and many other little upgrades. I have always wondered if they had better sprags in them? I would bet not but not sure?
