4r100 issue need help

Hey everyone new to the forum, I have a 2000 f350 with the 7.3 powerstroke couple days ago I was pulling my car trailer out of the snow here in MN and was having to rock the truck back and forth a little to get out of my yard got about half way out and lost reverse! Got the truck out today and truck will do the fallowing, move forward in park until park pin catches, do nothing in reverse, drive in neutral, and drive like normal in OD, OD off,2nd, and 1st gear selects. I took it down the highway in drive and trucks shifts as normal nice smooth firm shifts has this ever happened to anyone or is my trans toast any ideas?

P.s. Tranny temp was at about 150 but it was -15 outside trans has a aftermarket TC, HD Gears and rebuilt clutch packs about 1.5 yrs ago

Sounds like the shift linkage needs to be adjusted.
It should not drive in neutral.
This sounds like shift linkage only.
Give it a try.

I think the neutral switch could be the issue as well. Look on the driverside of the tranny, its a strange looking thing the shift linkage attaches to. I think its attached by either 2 or 3 small bolts and the holes the bolt are in are slotted. See if it looks like the neutral switch has shifted on those slots.

That is not the neutral safety switch it is the shift linkage there should be an indicator to align it to.
Good luck

Go to youtube and search for "Ford Steering Column Loose Shift Rail". He shows how to replace the shifter tube and shows the bracket on the end that usually loosens up on them.

I was trying to rock my 01 out of some snow last year and the shifter just went limp. I didn't have time to f with it and thought my trans was toast. Ford stealer charged me $600 to "replace the shifter rail". My 99 I just bought had a floppy shifter so I did some research and found all it needed was $6 worth of tube bushings and 45 min of my time. I also found the bracket on the end ready to fall off so I tightened the bolts down and am good.
