Well...let me study that for a few minutes...just kidding. I know a lot about how engines work, but I only have basic knowledge of transmissions, but I think I get basic point of what you are saying and I think I could tell if it was messing up. What would it cost to replace that piston at your shop for example? Thanks again for the well-written reply.
