The adapter is TG but the 4.7 gears in the rear case are MC total spline, all 23-spline. I'm pretty sure it's not the clutch because there is very clear grinding coming from the t-case area. I'm going to tear them and figure it out this week. I haven't had them out without the tranny as one big unit. Is it reasonable to just unbolt the crawl box from the tranny and drop them down (still supporting the tranny, of course)? I can't remember what's easiest...
