C6 transmission

I bought a used F150 with a junk yard FMX tranny in it. It originally had a C6 in it. I need to know if there are any variations in a C6 transmission other than 4wd or big block or small block bell housing? Thanks, novie777@bellsouth.net

C6 came with bell housings for small block, FE and 460. What motor do you have?

There are some internal differences, more clutch plates in the clutches for bigger motors and different valve bodys.

Hi, I've got a 351m with a FMX in it. I think the FMX is a junk yard tranny and not the original. The guy I bought the truck from said he had to re-route the cooling lines for the tranny he put in it. I understand the C6 is superior, but I'm looking at one out of a Lincoln and don't know if it will work. Thanks for your help. Novie

351m has the same bell housing as 385 series engines (351m,400,429,460). That lincoln tranny might work if it is a big block.

The shift lever probably is different. The yoke is different. It might not have provisions for a neutral / reverse switch. Rear mount may be in a different location.
