Anyone know how to identify a C6 without the tag? The ID tag is missing.

I've got a 1978 F250 Custom, 460, C6 (did have air, cruise, etc. but that's all gone). It does have water cooling lines.

AutoZone seems to think they just look up the year and that's good enough. If so that's fine but I'm a little shy of trusting that. :-) Surely it can't be that simple, can it?


Have misplaced all the engine stampings. Don't know if they'll help or not.

If I recall correctly the engine stampings say the motor came from a 1978 Lincoln.

 

ALL 1978/79 C6 transmissions used with a 460 engine have a transmission ID code prefix of: PJD.

The code for 1978 LTD/Mercury/Lincoln: PJD-AP3; AP4

The code for 1978/79 F Series trucks: PJD-J15; J16; L16; L17.

The transmissions internal parts are essentially the same.

If you need parts (or Ford part numbers) for ANY C6 transmission, I can post them.

NOTE: D1VE-6015-AC is the block casting number from 1971 thru early 1979 for ALL 460 engines, regardless of what the engine is in.

 

While you were writting that I found one of your other posts about the stamp number on the left side of the case. Didn't see it before, it's dark under there and 30 years worth of grease and dirt. :-)

The number I got doesn't look like those in this post though.

What I saw was D7AP-7006-AA. And there is a raised oval Ford emblem a couple of inches above and towards the front of the stamp.

 

D7AP-AA = 1977 Ford/Mercury/Lincoln C6 (D7TP is F Series; D7UP is Econoline).

1977 Car codes are: PJD-G10; G11, G12 / PJD-AH1 / PJD-AH2; AH3 / PJD-AR1 (whew!)

Regardless of all these &^$&&%^ codes, the internal parts are essentially the same.

What parts do you need? (Example: The front seal, O'ring and front pump gasket are the same for ALL C6's from 1966 to the end of production).

 

The whole transmission. :-)

I just want to make sure I get the right one the first time.

 

Oh...

Well I'd rather not have to list the entire trans..part by part...we'd be here for hours!

Just ask for one for a 1977 Lincoln Town Car.

Will you actually get this exact one?

NO!

Rebuilders remove those Ford ID tags for a very good reason. The ID can be tied directly to a certain year and model, what they don't want you to know. They'll sell you one for a 1976/78 model, or...

Why not rebuild your old one? You'll need seals and gaskets, small parts kit (snap rings and the like) bushings, filter, and the forward, direct and reverse clutches (steel & lined). Not much else goes wrong, usually.

Ford and parts stores sell a master overhaul kit...all the above parts are in it except for the filter.

 

That would be a hell of a list!! :-) AND if I put them all together the truck might go up but never backwards or forwards.

Anything particular about the transmission from a 77 Town Car?

I appreciate your help, again. I don't know why you have "dummy" in your online alias. From what I can tell you ain't no dummy about this stuff.

Thanks!

 

NumberDummy = old slang term for a Ford partsman.

NumberSmarty = CPA.

1977 Lincoln 460 C6 will be essentially the same as any 460 C6 from the mid to late 1970's.

 

Interesting FYI on prices.

AutoZone couldn't even order one. Advance Auto can.

If I order it for a 1977 Lincoln Town Car with a 460 it's $700.

If I order it for a 1978 F250 with a 460 it's only $500.

You know which one I'm ordering. :-)
