Just changed the tranny fluid on my 93ATX. I put a PROFormance filter on it (P/N's are SAG F254, ATC 86011E-E). I got it at the local Advance Auto (SKU # 5150655). Two things about the kit :
1) It has a neoprene Fel Pro Gasket on it - flexible & tough to line up the holes to put on, but no leaks
2) Ther is a rubber gasket on the neck of the filter. It was too long and would noot go far enough up into the transaxle. I had to use the old neck gasket, which was about half as tall (~1/4"-3/8"). Other than that, the kit was good.
If you want a rubber gasket with reinforced metal rings at the bolt holes, the tranny pan gasket from my wife's 3.8L Windstar lines up ewith the AXOD pan on my Sho. That P/N was FD6DP-7A191-AA (some other stuff beloew it was K9BOS and PA65-GF33<). Not sure if it would work very well becuase of the raised lip around the bolt holes on the SHO pan.
Hope this helps......
