Gentlemen! ............i couldn't help but notice this thread as i logged in today.
I have the same exact issue with my truck,a 92 ford f150 xlt 4.9 straight 6.
I posted my post about "my oil leak" last month.Long story short: we heard rapid "dinging" noises left and right,checked the oil and had abso no oil on the stick! i aint that dumb to let my engine go nowhere lower than a quart,but abso no oil? we filled it with 5 qts.The next day I drove it home,an 1 1/2 hr drive,and let it sit over night.the next day i rechecked the oil before i left home again,and once again.........no oil! i changed the filter thinking there was a crack in it.removing the drain plug,there was at least 2 qts that came out.I'm thinking the pan gasket blew and not the main seal?
my dad test drove it for a few days,not knowing what he did to it,if anything.
ever since i got it back,there hasn't been no oil leak.someone want to explain that? something major has happened,but just like that the problem went away? yeah right.or maybe it's just my lucky break.
i'm about to go recheck on it again here in a few just for the heck of it.

so did you rebuild the transmissions? something was in the fluid to make it thick. i wonder if it came off the bands or the friction plates themselves?
i just have seen metal shavings the most. shoot i blew the transmission in a 2004 f150 (forgot to take it out of overdrive while towing) when we pulled the pan there was shiny silver and red fluid in the pan. lucky we were able to replace it under warranty. and somehow that caused the gears to go bad and of course we didnt have anything for an open diff just limited slip diff's. what can i say work was slow that week. man i wish i still had that truck.

I was lucky to have some good teachers when I was coming up, if you can listen, you can learn.

My father was a diehard manual transmission man and when he had to get an automatic it was in a new 83 XL 4x2 F150 5.0 AOD and 3.55 . The truck was his daily driver but it also had the trailer package for his TT. He asked the service manager what to do to keep it healthy especially since he was hauling a 4500lb trailer to Florida from Maine and back. The service manager told him to change the trans fluid once a year right after hauling the trailer to Florida. My Dad did just that and we also had drain plug put in so we could change it easily. Good advice the Aod lasted over 218k miles and never gave any trouble.
I was always a Chevy/Mopar guy and was surprised that Dad, who never had owned a Ford since his 36 V8 Coupe after WW2 bought one. He flat out didn't like the 83 Dodge and felt that the two Chevy dealers were trying to sell him more truck then he wanted and didn't feel that they were that knowledgable about their product.
The local Ford dealer worked with him and he got just the truck he wanted. I have know owned three 92, 94, and 95 along with putting the last 90k on Dad's old 83 simply because Ford does make a better truck.
The transmission shop that I have used reflects what some of the others have said, service won't kill a healthy transmission.
Sorry for the long post

So I droped the trans pan and the magnet had about an eight of an inch of metal filings around it. They were super fine, it looked like mud. Does anyone know if that is a large amount or a normal amount of ware?
The fluid was pretty dark, like a dark cherry color, while in an aluminum tray that i used to drain it, however the filter I think was aftermarket so im thinking it was changed at least once in its liftime. The previous owner cross threaded two of the thread on the trans and thats why i had such a bad oil leak, the gasket itself wasnt that bad.
When i go to fill it up with the new fluid, do you keep adding till the level on the dipstick is full, then drive around to get the temp up and refil, or do i need to underfill knowing that it will expand?

I simply use a piece of thread and tie the gasket to the pan through the bolt holes at each corner you can leave the thread there or clip the knot and pull it out after you start several bolts. Keeps the gasket in place and makes it easy to remove next time

I installed the new gasket, which was pretty crappy. It just some cheap rubber. So of course its still leaking now. I chekced the pan, it was not warped. I may have over tightened. I may just cake some RTV on the outside of the gasket. Anyone have any better ideas besides me buying a new gasket and doing it all over again? Does anyone sell a higher quality gasket? I got the standard one they sell at advanced auto parts.
