Question Help!... 1996 Ford F250 7.3l 4x4

ok so please bear with me as this will very much come out sounding like chick talk.....
so i have a 1996 F250 xlt 7.3 4x4 a couple weeks ago pulling a loaded horse trailer down interstate. The truck was seeming to run fine. i did have some trouble with gear shifting (its a manual and im rusty) so i didnt think much of it.
but all of a sudden it makes a loud sound (almost felt as if we hit something) similar sound to when a transfer case jumps out of gear or whatever. (forgive me im female and truck knowledge is slim but i love my truck) all the while we basically lost power while the RPM shot way high. Now the truck cranks and runs fine but no gears so to speak it will go into 5th and still try to pull if you rev the rpms up enough but nothing with the lower gears or when clutch is pressed in. please help. Trying to figure out whats wrong with it.
I was told it could be the fly wheel, the clutch, or something with a transmission sensor??????
need i mention she has 360K miles

I would suspect the flywheel/clutch.

Do you know if it has ever been changed out? I know 360K miles is a lot if it is the factory clutch but even if it is on it's second or even third it is something to look at.

The transmissions on these trucks are fairly robust, and there are no sensors on a 5 speed manual.

By the way I'll have a moderator move this up to the 96 7.3 forum since it is a Powerstroke.

Im not really sure. Im not very truck/engine savy. i bought it only about a month ago to pull my horse trailer and get better fuel mileage than my chevy gas burner and it did do that. ive been doing tons of research and im not scared of dirty work just need a place to start . but i will try to ask the previous owner. and thanks for the tip on the sensor as well as having the post moved

It might be hard for to to see what is happening but it might give you a clue but you can pull the inspection cover off of the bellhousing under the truck where the transmission attaches to the engine.

If the clutch or flywheel is or started to come apart there will be pieces of material in the pan type cover. There are only 4 bolts that hold this pan on and it should come right off.

Welll..... i know exactly what part you’re talking about as that cover is missing..... 😐 if i can get this to cooperate I’ll post video of it running and flywheel spinning (it threw sparks there right after it happened)

The truck cranks and runs but it only seems to catch in 5th gear.

If it is throwing sparks it sounds like it is still the dual mass flywheel and it is starting to come apart. It is held together with springs and the springs coming loose could be what is throwing the sparks as the grind away.

Take a good look at the transmission bellhousing to make sure it hasn't cracked, which does happen with dualmass flywheels that go bad. Cheers!
