o k my #3 son & i are working on his 79 thunderbird ,& we r doing a tranny oil & filter change. The car has a 351 windsor with a supposed c4 tranny . Went to toon town( 60 miles) to parts sourse to get filter. Well the c4 filter not even close , c3 closer but no cigar, c6 way out in left field. Oh by the way its a 3 speed auto no od no lock up . I called a friend of mine & he said there was yet another tranny ford used amx or thx or something wierd like that .I told the parts guy the type(remembered proper name then) & got one of those r u crazy looks.So any help greatly appriecated , the filter is held on with a small single clip at the rear & a wire hooked kitty corner on the front there is a found hole in top where filter plugs in . I think there is 13 bolts in pan,its small the c4 is close but not good enough . later bake.
The transmission is probably an FMX. Look up the parts yourself on RockAuto.com, then give the part number to the parts store. http://www.rockauto.com/catalog/raframecatalog.php
my 1977 LTD Landau has the FMX trans behind the 400 engine on the door sticker,the trans code will be "X" for the FMX trans ya want weird? how about their V8 firing orders, now THOSE are weird! uzzled:
Judas priest i knew u guys would come through .I dont think i've stumped any one yet with my silly questions. Now i know why i just ask here about any of my cars . many,many thanks. bake
The FMX is an older design, from the late 50's early 60's. Might be heavy,but very strong. The C-4 & C-6's were 60's and later in most installations. That FMX that you have is still working, almost 30 years after it was built. Be glad it's not an early C-4.
If I recall correctly, the C6 was generally thought to be the strongest Ford transmission, generally used with the FE and 385 series big blocks, but they were only used behind the 351 in the late 60's and early 70's, and are hard to find. (Ford small blocks have a different bolt pattern than the big blocks) Next would be the FMX, which has a cast iron case. It is a stout unit, which could be built to withstand some serious power. I had one done many years ago, and could not break it. The C4 is the everyday small block version, good in stock form behind a stock small block. I broke about 4 of these behind a mildly built 351 Cleveland in the late 70's. Yes, I was stubborn, but I could always find them cheap.:laugh: Then I put in an FMX, no more breakage.
Hey guts thats bloody great to hear, a least its not a boat ancohor . Got on pro kings web site and asked about a filter kit.The local parts stores seem to mostly carry pro king. And low & behold the #is fk-111 & its found at canadian tire part# 17-4704.Hope this helps any of my fellow canucks, i dont think crappy tire as we callit up here is south of the 49 th. Later bake
I do not believe that your FMX will bolt up to a 460. You will need a big block C6 trans, which most likely would already be attached to the 460. What is currently in your LTD? I'm betting it's a 400 M engine, which is a tall deck version of the 351 C.
yep, it has a 400 M in it. seems to be fairly good on gas (future plan is to put a 460 in it, and make an unmarked police pursuit car clone :Brow: ) and I also found out, that 5 on 5 bolt circle big Buick wheels will fit on a Ford I have a set of like new mud/snow radials,mounted on Buick wheels on the rear of My LTD (after I removed all those studs) they fit perfectly.
Now that you mention it, that is correct. Thus, The Buick Nut should already have a C6 in his LTD, as I do not believe that the FMX was used with those engines, but I could be wrong (again:laugh: ). I'm a Ford guy from way back, and even I get confused by their combinations.ou: I do know that the small block Windsor, and probably the Cleveland engines, did not share the big block bolt patterns.
and here are the trans code letters : C4 = W C6 = U FMX= X CW=Y C6 = Z (Police and trailer towing) mine has the FMX
Now that I'm late to the post. I'll put my 20 years of Ford parts epcerience to work. The conclusion you have arrived at is correct about a FMX. The code for the trans, trim, engine, rear end, etc. is on the certification label. It's too bad that you don't come across a experienced "parts counterman" as easily as in the past; I was expendable at the last dealer I worked for. Then they threw away my library of info soon there after along with cleaning house of almost everyone in the department. Within three weeks a combined 120 years of Ford parts knowledge walked out the door. Remember to use type F transmission fluid in it so it will continue to function if it has never been overhauled or rebuilt.
