Mush-O-Matic

Hello Gentlemen !!! I'm a newbie with a question . I've got a 57 Ford F100 with a 223 inline six . Behind it I have a Ford-O-Matic thats gone south. Will a C4 bolt in place of the mush-o-matic if I change the torque convertor ??? Or is there anything else that will bolt in its place ??? I've been on other boards and all I get is "find a donor car with a V8 and change it all over " The old 223 runs like a champ and I hate to throw it to the side ...



Thanks

 

The short answer is, no, on the C4. It may be possible to use a FMX, depending on a couple of things. The FMX is a descendant of the Ford_O-Matic/Merc-O-Matic with a full, separate, three speed pattern (as opposed to the "hidden" gear on the Ford-O, & some actually only had two speeds, period). For the most part, considering the truck side bell mounts, bell pattern, & so forth, the easiest thing is to rebuild the Ford-O.

If the shifting of the Ford-O-Matic doesn't thrill ya but you want/need to keep it an automatic, Jim Paquet of JPT Transmissions or Jay at Broader Performance can do some performance mods to the Ford-O. There may be some trans guys on the HAMB that can help out too...

Nothin' wrong with a 223.

If you want, I can scrounge up the FMX swap details, though it might take a day or two.

 

Thanks Homespun91 for the reply ... Your dealing with a newbie ...What's a FMX ? Is it a auto also or a manual trans ? Are they easier to locate than a Ford-O-Matic or easier to rebuild ? Sorry for the dumb questions but this is all new to me

Thanks

 

So'm I.

Yeah, the FMX is an automatic. As mentioned, it's a direct descendent of the Ford-O-Matic, but with a conventional 3 speed pattern of P R N D 2 1. It has a cast iron case, too.

They are easier to find; generally behind a 302 or 351C in mid-size cars like a Torino, & in Mustangs, Rancheros, etc. Late '60s- mid '70s. They aren't harder or easier to build necessarily, but more trans guys will have seen them than have seen the Ford-O. They are fairly similar to the Ford-O internally & some parts interchange. Be advised that it's not exactly a direct bolt-in for a Ford-O, but not too bad.
