Default c 4 ? trans

I thought I'd double check with all the experience in this forum.
A 1969 Mustang 351w 4 barrel , did it come with a c4 transmission.
Is the tranny marked somewhere I can check?
Thanks

It could have a C4 or an FMX. Easy to tell:
C4 - All aluminum removeable bell
FMX - cast iron case aluminum removeable bell
C6 - all aluminum no removeable bell

I have never seen a 351 with a factory-installed C4. Of course, any "Bubba" could put one in there. Look for the iron center case, as mentioned above.

All 69-70 351-equipped Mustangs had the FMX. 71-73 typically had an FMX on 351C 2V engines, and the C6 on 351C 4V engines, although exceptions have been noted.
