Gerald, the lack of aftermarket support is surprising. I've got the same tranny in my LJ, and when AA came out with the Rubicrawler, I thought that would prompt other companies to come out with some additional pieces, but there hasn't been much. I think there is a guy on JF who has had excellent success with some different valve bodies. I haven't paid much attention as I plan to put an LS motor and GM tranny in my LJ when the driveline grenades.
