My conversation with Lenny at UCC was that I wanted as tight a converter as I could get given the limitations of a 9" converter dealing with gobs of torque. He said this is as tight as he can get a 9".

He also recommended that I run the thicker John Deere Hy-Gard rather than ATF. And not the generic brands of hydrostat fluids either. It seems that the Hy-Gard has the standard and then has a low viscosity version. Most generic brands tend to be the thinner viscosity. And, of course more viscosity helps tighten up the converter. I also run a big tranny cooler to help all it can. Hy-Gard is roughly equivalent to 10w30 oil. I have thought about trying some 50 or 60 weight oil mixed with the tranny fluid, but I just haven't gotten around to it. I do have some ATF in there just to give it some color, making it easier to see on the stick.

As for the snout, I just lightly touched up the snout and crank until it would go together.
