FMX didn't come out until 1966....

I know. I was basing this on the theory that the trans may have been the original to the motor in the Tbird. In 56 it would had to have been a Ford O. I did not notice that you had positively ID'd as a FMX
 
If an FMX, there is no TV rod. It should have a modulator valve unless someone put a manual shift valve body in it. All you will need is a downshift cable, again if not upgraded with a manual valve body.


It was introduced in the 1968 model year. Is the shift pattern 1-2-3 Select Shift?
 
I am 99% sure you have a 1956 Ford Ford-o-matic (early) trans. Early was air cooled, late 56 was liquid.
That ugly throttle BRACKET you are referring to, is for a 1956 car with a Teapot 4 bbl.
That bracket has been modified in the front area to accept a CABLE of some sort for throttle activation.
The existing ROD going to the carb is to insure that the kick-down rod (going down to trans), gets activated properly.
That's all I can tell from the photo with my old eyes

CrazyTed, could you crawl under your car and snap and post a picture of the vacuum modulator on the back of the trans? Hopefully this will end the endless speculation about what trans you have! Thanks.
 
OH CrazyTed ?

Would this setup look any nicer to you? It will also operate a FOM -

What I was trying to get across was the use of a 55/56 bracket on a ECZ-B. Both ST and AT transmission brackets are similar in appearance.

It may be that this setup would be more pleasing to the OP's eyes.

I'm not sure an FMX will fit a Y-block. They had FOM and COM transmissions back in the day but the FMX is a bit different. It's is a cross between the FX small case and MX medium case Cruise-O-Matics. Sort of the best of both worlds.

I'm thinking (maybe just assuming) that a Y-block Fordomatic bell housing will bolt to a FMX case.
 
Yes the FMX can mate to a Fordo bell housing with a few modifications. I also used a FMX torque converter.

I used Lokar cables for throttle and kickdown. That was a few years ago. Now I am running a C-4 with a Gear Vendor. Still using the same cable setup tho.

Nice looking car CrazyTed...:cool::cool:
 
Sorry to drift OT, but,

“ Now I am running a C-4 with a Gear Vendor.”

Now that has to be a sweet combo. Great looking set up.

I think the Hoosier Hurricane has a number of post over at yblocksforever regarding the FMX/Yblock conversion.
 
A lot of stuff is adaptable between all of the Borg Warner designs. Folks used to adapt COM parts with FOM parts to get a dual range shift. I'm not surprised that the FMX can fit in the mix even though it has more than one tail shaft type. I hear that those 58 to 62 COM/Y-Block transmissions are getting harder to source. The bell housing is a must for conversions. I think I'd look into an AOD transmission since it is based on the FMX and has the overdrive. That would be worlds better than just a 3-speed with 1 to 1 final drive. It would make it worth the effort for certain. This is a link to some info on an adapter kit. http://www.secondchancegarage.com/public/277.cfm

Plus, with the AOD you get overdrive and lockup converter without any electrical/electronics whatsoever!
 
OK ...

Just to clear-up my original post regarding 55/56 throttle linkage use on a 57 intake (the photo showing OD linkage), here is a photo just recently posted on the other forum showing a 55 BIRD with an ECZ-B intake using the original 55 throttle linkage. One other poster in the same thread said his bracket install needed to be shimmed.

The FMX came out in '58 or '59 for sure. Dad's '59 had an FMX for sure. The C6 came out in '66 and won't fit the Y block. The FMX will fit with the right parts.

The FMX was introduced in the 1968 model run. FORD acquired BW design rights and put the MX internals into the FX main case and deleting the rear pump.

The CRUISE-O-MATIC (market name designation) DUAL RANGE SERIES (FX - MX - HX) was introduced on the 1958 model run. The FORD-O-MATIC was retained for certain models and the F/M/2 was introduced in the 1959 model year. The modulator valve was incorporated in the 1961 model year, eliminating the TV shift control.
