Cruise o matic help

[5lmustang]

I've got a 67 f100 with a 352. I want to put a cruise o matic back into it like it had from the factory, it has a c6 right now. What I need to know is what cruise o matics will work in my truck? What codes , can I use one from a car or is the gearing useless for a truck?

You may want to introduce yourself on the welcome page.

Why do you want to use a '67 transmission?

According to the factory manuals, the 1967 ford had a HD MX transmission which some call it a FMX. From what I have read, the transmission is difficult to find and not many parts are available. Cruise o matic was a generic term for a number of transmissions. I suggest do some additional research. I plan to install a c6 in my 67 when the time comes.

Thanks for the help blue250 it sounds like you've already gone through the transmission ordeal. I want it to look factory new when I'm done restoring it that's why I was looking into the X transmissions. I guess it dosent have to be a x tranny and c6 parts are more abundant...

Damn it, now I have to consider another transmission option!

I will probably keep the c6 for practical reasons. Thanks blue250

Hi, if your truck had a COM in it originally, & you want to do a completely original restoration. They are iron case units, not that difficult to build, somewhat harder than a C4 or C6, & yes a bit more difficult to find, but they are out there...The C4 & C6 are better units as they were designed after the COM & made some improvements .But the MX/ FMX were OK in their time. If you are judged in original construction, A sharp judge will pick this up. All depends where you want to go....If you are just building a good rider, the C4 & C6 are easier to find & less costly to build...... ON the COM, The gearing is the same pick up or car....The case is iron & the bell housing bolts on....There is not much in the way of HD parts available for these...as some one else noted---Ford called everything COM...., but there were 3 diff. units used..........Donnie

I've got an original 67 COM in my Ranger, never gave it much thought, haven't researched it much either. Good to know it's an odd duck... like half the **** in the 67's LOL

The 67 MX Cruiso is a one-year only transmission. Earlier models will bolt up, but they have the early shift patterns. In 1967 all manufacturers changed from a hodge-podge of shift patterns to a standardized shift pattern.

I don't remember the exact code for the transmission although I think it may have been PFB-A. 5 years ago I had 3 of them on the shelf, but have since parted them all out.

You could install an earlier MX and change the valve body to a 67 valve body, but then the numbers won't match the vehicle.
