Fluid Puking from Rear of Trans

So I was scheduled to go look at a truck this weekend. Been searching for another PSD for a while, and thought I'd nailed down just what I was looking for. After the 4 hour drive, found not what I was looking for, but was able to get the price down enough that I now have a new project truck. Now if you all could help me with the first, and most important issue of the project.

Basic Truck info: 2000 F250 Crew 7.3 4x4. 190k miles. Other than this fluid issue it also vibrates really bad from about 45 mph and higher, stopping when the accelerator is let go. Shifts just fine

There is a crazy leak from the top, could be where the tailshaft extension seal is, but it seems to be coming down from the top somewhere. Now idling in park or neutral it's leaking a good bit, but when I put the trans in reverse it just start puking out all over.

I will be dropping the trans and transfer case down as soon as I can, but with this not being my daily driver I'm not in a rush. I'm trying to find out as much as I can ahead of time.

If anyone can bounce some ideas off of me I would appreciate it. My next steps is to bring it down and check for case cracks and change the tailshaft extension seal, but otherwise I need some ideas.

Thanks

David

Before you drop the transmission check your drive shaft for slack, could be carrier bearing that caused the issue to begin with or a u-joint going bad.

That was in the plans as well. I'm hoping the u-joints are the reason for the vibration I'm getting. Although I was planning to get a picture posted of my driveshaft, definitely doesn't look like the same one I had in my old Excursion. It looks to be a one-piece.....

How about another bump for more ideas. Still haven't had a chance to get back to it. After some more reading I'm also going to check the vent tube, as well as the trans cooler to see if they're clogged.

Also trying to get Ford to run an oasis for me to see if the reman was installed at Ford with a cooler flush or replacement.

The fact that it spews when put in gear makes believe it's fluid passage somehow, and the fact that the trans shifts great leads me to believe it's not an internal passage blockage.

Well I have a small update. Crawled under this afternoon and was able to chalk the wheels while I put it in reverse neutral and drive. The leak is slow in park, neutral and drive and is still a steady stream in reverse. What I can tell is that it seems to come from the passenger side top extension housing bolt. I haven't been able to check it with a mirror yet but I will as soon as possible.

My hope is that the bolt is simply loose, although it wouldn't turn with my fingers. My biggest concern at this point is that the case is cracked there.

Any opinions or suggestions are welcomed as always.

Another update.

Took down the transfer case and extension housing tonight to replace the gasket. This gave me a better view of the top. I wish I were kidding but check out this picture, this case has been caked in JB WELD to cover a crack or pinhole. Unbelievable...the only thing left to try is to get somebody up try to weld up the case. I will be pulling the rest of the trans down tomorrow to scrape that junk off and check it out.

There is someone locally that has everything for a zf swap but I was really hoping to save the funds for an interior revamp.

As always. Suggestions and opinions are welcome.

Bueller......

Okay got the trans down tonight. And another stone is uncovered. Top Driver side bellhousing bolt hole was cracked when I pulled it down. The plan now is to wire wheel off the JB Weld that is smeared on there and then braze closed the hole with some aluminum.

At this point I still have put any money in to it, just a bunch of time pulling the trans down. Hopefully I will button it up and put in back to use, but if it ends up still leaking, or begins to perform poorly I will be putting in a ZF.

All comments welcome.
