Transmission rebuild, was quite the saga.
Nothing has come easy with this car, after installing a trans-go pressure regulator the trans decided to act up even more to the point I flat bedded the car home.
Called my rebuilder in Chicago (I live in Texas) and arranged to haul it up there for repair.
After rebuild things still weren't perfect, ended up buying a replacement valve body from Erikkson Industries. This cured the rest of the trans issues.
