If you changed the head gasket, it is likely that you had to disconnect some vacuum lines. My tranny shifted perfectly before I replaced my head gasket, and now I have flaring. I know it is vacuum related, but i haven't figured it out yet.

The K1 spring kit is a cheap $10 fix. Might as well try is. It made the difference on my two SD's.
