I am working on my '66. It was my great grandfather, grandfather, father's...now mine! It has some work to go (has been an old farm truck), but I want to bring it back. It has the original FE 352 and manual transmission. I have the engine out and I am considering putting in an automatic transmission. Thoughts?

What years or Ford transmissions will match up?

Thanks!

What I started with...


Currently...

 

the c6 transmission will fit fine, and was used for many years. it should be fairly cheap to find one (have seen from 50-200 bucks used)

If you have a three on the tree you might need to replace the column(Not sure about converting it to the automatic column) but with a 4 on the floor you can very easily mate up a lokar automatic floor shifter.

 

by the way, welcome to FTE!! you'll find some great guys on here who are very knowledgeable. Also, look on the inside of your driver door (The part that is covered when the door is shut) and write down the warranty plate. Number Dummy (Or someone else) will decode it for you! quite interesting to find out when and where the truck was built.

 

yeah go with the c6 it is alot better than the old fmx c4 cruise-o-matic that i have in mine till i can get the c6

 

ya, I can't wait to get rid of my c4 and drop in a c6.

 

I also welcome you aboard! I would also check the trans hump height for clearance; don't really remenber the different heights; but there is about 2 to 3 different ones. I own a 65 model and had alittle clearance problem installing a C-6 behind a little old 302, which prior to this engine combo I had a 300 & C-4 trans. I had to cut out the center protion of my trans hump and relace with a taller model trans floor plate out of a salvage yard 65 model. Oh; and by the way my truck was a orginial 352 & Cruise-o-matic set up from factory.
Just a thought!!! And again welcome.

C-6's are great heavier duty transmissions.Just remember they suck power to operate(I have heard 35-50hp).It all depends on the job.F-250 it is mandatory unless you like the stick.

as far as small block or six. f100 I will take a c-4 everyday.

heck my 500hp blown small block mustang went 2 tenths faster with a c-4 versus a proshifted tremec.

basically they are both good the job just has to be clear.

 

There is no such thing as an FMX C4. The C4 & FMX are two totally different transmissions.

C4's were only used with 240/300 I-6's, 1969 and later 302's.

FMX's were not used in trucks, except 1973/77 F350's with 300 I-6's.

1965/67 F100/350's used MX Cruise-O-Matic.

 

Just make sure you get a C6 for a FE engine, the C6 off a 429/460 will NOT bolt to a 352.
I'm running a C6 with a 23in Lokar shifter. Wouldn't have it any other way.

 

Hey guys im new to the site and i have found some great info from the group. Im tryn to find a c6 transmission to turn it into automatic. Im having a hard time finding a good source for it. I have. A 352 fe engine in it with a three speed manual tranny which is shot. Any help woikd be appreciated.

 

The C6 was first offered for F100/350's in 1968, used thru 1976 with 360/390's.

Installed in Passenger Cars ~ 1966/67 410 (Mercury Parklane only) / 1966/70 428 / 1968 427 / 1968/71 390.

All these are FE engines, as is the 352.

1965/67 F100/350 352's came with MX Cruise-O-Matic. A good trans in its day, but the C6 is superior, and C6 parts are much easier to find.

1965/67 Passenger Cars with 352's & 390's also used MX Cruise-O-Matic.

1968 was the only year Ford offered the 427 HiPo with an A/T.

 

I know that this is an older thread. I am a new member and have a 1965 F100 with a 352 CI. It has an "A" for the transmission code in the warranty plate. So with researching threads on this site (and I did a bunch before asking my first question) I was able to figure out that of the seven or more different trannys, it is the 3-speed Ford Standard Duty Transmission. I have a C-6 transmission from a 1978 Ford F250 that was paired with a 460 CI engine. I saw someone posted that a C-6 from a 460 will not bold up to my 352. Is there a conversion kit/Plate? Or is this just not possible. Also, is this worth doing? Benefits/Drawback/Headaches??? Thanks in advance. This site is priceless!

 

No, the 351M/400, 429/460 pattern transmission is not worth adapting. The FE uses a stand alone bolt pattern for the bell. Find a specific FE C6.

Look on craigs list an in older yards. They will be found in pre 77 trucks and cars equipped with FE engines.

Thanks for the info. Maybe I can find someone on craigslist who would swap a FE C6 for my 460 C6. Thanks for the help.

 

You might even be able to swing a deal with a yard honestly, especially if its good working order The BBF bellhousing pattern is far more in demand than the FE bellhousing pattern.
