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.

 

It isn't a vacuum problem, it is a failed transmission. Sorry.

 

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.

 

I put a rebuilt E4OD in my 97 a few years ago. It cost me somewhere around $2,600 installed.

 

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.

 

You might want to check these screws.

Is that on the transfercase?

 

No it is at the bottom of the steering column.

 

Hmm, alright, thanks I'll take a look tomorrow

 

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.

 

Reverse in the E4OD is fully mechanical/hydraulic. Electronics are not involved in reverse. You could completely unplug it and it will stil go into reverse.

 

If it's fried it needs to be replaced. But it won't fix your problem.

 

Except for my truck is only going forward now. And only in 4low with hubs UNLOCKED.

 

It sounds like either your transfer case is broken, or you have burnt up clutches inside your transmission.
