Moves forward in reverse
So I have a 1992 Ford f250 it has a newer 460 big block engine in it, I got it used, currently the third owner, and the transmission doesn't go in reverse there's like, nothing. However, it goes forwards... In reverse what the heck do I do, is it a vacuum? Clutch plate, keep in mind it's automatic and I have yet to find out what type but I'm at a loss right now, and if you can't already tell, it's sort-of a problem, any help would be obliged.

Hmm, how much is a new one for it? And are you dead sure on the new tranny because it was almost engaging the other day but now... It just goes forewards.

A new rebuilt E4OD will set you back over a grand. Junk yard is your best bet if you're on a budget.
As for what would make it go forward, in reverse? I suspect hydraulic failure inside the valve body, with fluid leaking to places it shouldn't go.

Just a thought, but if the cable/linkage are out of adjustment, it might be going to N when you think it is P and the forward might just be because it not hitting R. Might be worth a look.

So an update on my transmission. It's a neutral safety switch (also known as prndl switch) and mine is actually fried. You can check them with the continuity mode of a multimeter. The the transmission tells the computer what gear it's in. Then the computer puts it in that gear. Makes like almost no sense I know. However all I've been told is correct so far so I'm grabbing a switch from the wreckers to test and hopefully it's functioning.
