I was driving my 95' f-250 with the 351w and E4OD and lost all gears including park and made a clunk sound when taking off. I pulled the pan and did not see any chunks but there was a good amount of shavings (transmission fluid probably had not been changed in 100k miles its my dads old work truck). Pulled the cover off the transfer case and it looked good. Filled transmission back up to test pressure and it went into park so I ruled out the transfer case as being the problem. Tested the pressure it was in the ballpark where it should be. Got the codes from it with a OBD 1 scanner, 632, and 452. Check engine light comes on at 3k rpm in drive, and overdrive light flashes. I'm out of ideas to figure out what's wrong with it and could really use some help, truck still has not moved since it lost gears. Thank you in advance for your response!
Losing all gears including park is either a broken output shaft or a failed transfer case. Neither one can fix themselves. So your symptoms don't make any sense to me.
Neither of those codes can explain it, either.
I'm sorry, but I have no idea other than a broken output shaft (this would be the first output shaft breaking that I've ever heard of) or a failed transfer case.

confirm you are actually connected to your shifter on the trans , maybe while holding brake have someone actuate it without the shifter attached, see if you can get detents and any engine load differences
I thought about that but it doesn’t roll in PARK has me stumped. Unless there are a couple broken teeth and it rolls a little bit until it gets to a good spot on the gear then stops
