i only know basics of the auto tranny, but my guess would be that you may have lost a planet carrier, or clutches...

Before you get into the tranmission check the slop in the clutch pedal bushings mine had massive amounts of play and when I replaced them it made a big differance. Royal purpel ATF helped alot to. O yea our manny tranys use ATF.
PS You do have a manual trans right?

I've noticed that if I let mine idle in neutral for a while and then try to stick it into reverse that it will grind, especially if the trans is cold. But if I first try to stick it into first or second and then go to reverse it will not. I don't think R is synchronized, so there's nothing to help mesh the gears smoothly when everything is rolling in there.

Your right that reverse in not synked. I have never had a problem with grinding going into reverse but it would pop out unless I double clutch it. Do you guys have that problem to? The pedal fix and royal purple helped.

Scatgo, I don't have any troubles popping out of gear. I changed my axles, xfer, and transmission over to RP a few weeks ago, but didn't notice much change in the shifting. My rig has ~228K on it, so I'm sure the transmission is well worn. I'm thankful it still works.
