Can somebody ID this trans?

[eskelton]

Ive got a transmission ive been told that could possibly be a ford 400. How do i id it if it is? I have the numbers off the side of the transmission ( Driver side of it ). Can someone tell me by these numbers what it may be?

Hi, D4 only means that part was introduced into the line in that year....D=7 4 is the first year of production. To the best of my knowledge Ford didn't have a model 400.........General Motors did.........Show us a complete photo & we can tell you what you have............Donnie

looks like it may be a fmx trans for a ford 400m motor.

I think that HIboy is correct....looks like a center support bolt showing above the case #'s....donnie

Whats a fmx trans?? Is it a good trans to build or is it junk to just toss?

Here's the other pictures i have of it.

I think there are 3 bell housings for the C6 and several variations.

The FE, Series 335/385 (351m, 400, 429, and 460), and the small block (inline, 351c, 351w, 302, 289). The 351m and 400 were a variation of the 351c. Do an internet search for more details.

The cruise-a-matic to AOD were continuous development of the same design. Each was built for a specific purpose, some weaker, some stronger.

The (mx-hd in 1967) FMX can be rebuilt but upgrades are limited. The C6 is better for modifications. It all depends what you are trying to do and your budget.

Thanks for the info. Ill look em up and see what i can't find out. I am just debating on whether or not to take my truck and convert it to a auto truck or if i should dump the ole 3 speed and upgrade to a 4 speed

another thing you can try is pull the pan and get the filter or screen number and ask the auto parts store what application it fits. kinda like reverse dissection....should be able to give you a application at least.

There should be a tag attached to one of the extension bolts....that info will narrow down your search...they are not a difficult trans to build, they just use a diff. geartrain that the C4 & C6......That trans has been in use since the 1950's, various version's of it are still using the Ravigneaux complex gear train...harder to repair than the C4 & C6 which use a Simpson gear train...E.G.. 2 separate planetary gear sets..on those units you can replace either 1 or the other planetary if 1 is faulty..where with the French gear set things get more complicated....Not a bad trans, but it would be my 3rd choice of the 3 speed's......donnie

It looks like a bolt on bellhousing. I know C4s had them ,did the FMX too ?

[Donnie]

Yes, the Iron case units actually bolted from the rear, where as the C4 bolted from inside the bell......Donnie
