94 dodge 4x4 nv4500 blew all gears
Well, today was my unlucky day, lost all the gears in my NV4500
driving about 60MPH on engine brakes down a hill, it jumped out of 5th (4.10 gear ratio), I clutched, put it back in, and kept driving for about a mile, where there was a long hill, I rolled into it a little just to maintain speed, and suddenly I had nothing, tried 4th, nothing, stopped, and it seems like the clutch doesn't want to disengage properly, but can't quite tell, got it into all the gears and didn't have anything.. seems to be noisy and there's an occasional scratch in most gears. (I didn't think of trying reverse), tried low range on the transfer case, nothing changed, and no the driveshafts aren't turning
Any idea what let loose? since the clutch doesn't seem to behave properly I'm thinking an input shaft bearing/gear could jam the clutch a little if the shaft gets cockeyed (yeah, not very likely)... what about output shaft-Tcase splines? it would be strange because I was under pretty low power and the clutch issue
I have another tranny with 250,000 miles on it... no 5th (I'd steal the guts from this one)
details of the truck in my sig

Well, I'm told the clutch may have sheared the rivets on the hub, the long and the short of it is that I'm going to go home, and in the next few days take it all apart (take PTO covers off first) and unless you're going to place bets on what's wrong, I'm not going to be needing this post anymore
cheers all anyhow

Well, I dropped the tranny last night (internals are fine), but the clutch came out in about 30 pieces.. the center hub totally blew up... Getting a Southbend 475HP with 13" flywheel.. that should solve that problem
