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.The 42rle has been completely gone thru but there is not much after market support for it. Any plastic parts have been repalced. It is a electronically controlled OD so we are using the OEM computer to control it.
The torque converter is were we spent money to make it last. All of the plastic has been removed and the fins brazed so they don't detonate at speed. Then balanced and tested.
Atlas 3.0 behind the tranny.
