    Buy a new transgo seperator plate and put it in stock to start with to see if you like the feel. You can drop it out and open the passages a little later if you don't like how the shifts feel. You might consider some new torlon check balls, too. Be sure to check all holes in the plate and deburr any sharp edges on the new plate. Add a drain plug to the pan if you don't have one already.
