The ***** can only fall out of valve body if you take the valve body apart.
To change the filter you don't need to take the valve body apart :P
I'd change the filter on the table just cuz..... I'm sure you've noticed by now, the valve body will leak way more fluid than you'd think possible, so be wary about flipping it over and more will gush out randomly.
The valve body to transmission (3/8 head) bolts are 100inch lbs. The rest are listed below in a picture I took.
If you don't have an inch lb torque wrench just get them tight with a nut driver, or a speed wrench. Under tightening isn't a massive issue, just don't get crazy over tightening them.

Just to finish off the thread, turns out for me it was the outer O-ring on the kick down that failed and caused the leak. I went to a local transmission shop and the guy at the counter gave me a new one, no charge. He gave me the new "flat" style seal that isn't actually an o-ring, but looks more like a tiny little tire. I popped it in no problem and the leak stopped. Thanks for all the info guys. I appreciate it!
I'm having the same issue and reading this thread has me wondering - if it's the O-ring on the kickdown linkage, which (to me) would be the last line of defense, so to speak, wouldn't that mean that there is a leak further in? Meaning the seal at the shifter linkage? For my sake, I'm hoping my leak is the outer O-ring. But if it is, I'm afraid that means the inner seal is also bad to allow fluid to get to the outer O-ring. Unless, this is by design.
From what I read, it doesn't sound all that bad to change out either, but, I'd only like to do what's necessary to stop the leak. So, far I've done all the work on my truck to get it running again, but, I've never worked on a transmission before, so the thought of opening mine up, scares the bee-g-sus out of me.

Reason: add picture
Anyone know what size that little o-ring is at the kickdown? I replaced the seal and the o-ring, but I don't think the o-ring I used was exactly the right size. I still have a leak at that point. So, now I need to find the correct o-ring to put in there. Any help?
I have a '75 F250, FE390 w/ a C6. There is transmission fluid slowly leaking from the linkage on the transmission where the shifter levers attach. Is there some kind of seal that might have failed? It's the area highlighted with light in the photo.
Also, there seems to be some sort of plug next to the linkage, I tried to tighten that in case it was loose and the source of the fluid, but didn't make a difference. What is that plug for?
IIRC, that “plug” is actually the intermediate band adjustment.
you may want to loosen it and torque it to proper setting, if you messed with it.
