Okay, I tried a standard 'easy' transmission filter change.
I can't believe it, I've totally lost two of the screws.

Does anybody know a source of transmission filter screw set for a C6 Auto off a 89 F250??? (not the pan, for the filter)

After just finishing a engine removal/install job on a Subaru, you'd think I'd know how to keep track of screws/bolts.

 

Rats, no reponses eh?
Guess I'll just install with one screw missing.

 

Since it is a c-6 it should be standard thread probably 8-32 or 10-32 thread. If you bring the screw into like say Fastenal or hardware store they should be able to match it something close. I wouldnt put it together with one screw missing.

 

match the screw or go to ford parts department and get some.
