Keep in mind when looking at casting numbers, that the number itself does not mean the year it was cast. Something starting with CONN could have been used for 3 straight years. It only gives you a rough idea.

Also, a bunch of castings could have been made in 1960, and then machined and assembled over the next few years.

Thanks for the input. What confuses me is this. With Ford part numbers, the first letter indicates the decade and the following number the year when the part was given the part number, and usually put into use. But the New Holland parts catalog states the DDC was used starting January 1963, which makes sense with the C3NN part number (1963), but C0NN (1960) would be before that date so theoretically would not indicate a DDC. I suppose the part could have been designed in 1960 for the DDC, but not actually used until 1963, but that"s a pretty big spread in years. Or maybe the New Holland catalog date is wrong for the DDC implementation.

The C0NN casting number just means that the casting was designed in 1960. The design could have been finished and the designs filed with their records department on 12/31/60, and then they could have started using that casting to build transmissions as early as May or June of 1962 for tractors they would be building in August of 1962, which was about when they started making the new 1963 model year tractors, but since they were officially 1963 model year tractors, the part number would have started C3NN, not C2NN. So that's a spread of only about a year and a half between designing the casting and starting to build transmissions using that casting. I figure in reality it was probably somewhere in the 1.5 to 2 year range. That makes sense to me if they wanted to build some DDC transmissions to field test the new design before they started rolling them out to customers, especially after the black eye that they had already taken from rushing the first S-O-S design out the door.

It makes total sense that they would have redesigned the casting back in 1960 to build some research and development models for the DDC before going into full production in 1963. Don't know why that didn't occur to me. Guess I'm used to the car part numbers where the decade and year usually refer to the first model year the part was used. I'm sure there was more development time allowed on the SOS DDC, especially after their ORC debacle. Thanks Sean.

This has been an interesting thread. Didn't think it would create so many responses. Thanks everyone.

Hello Sean , The C0NN7006B transmissions were installed in the 1962 BLUE and GRAY TRACTORS built in AUGUST of 1962 until Dec. of 1962 and they were sold as 1962 tractors(since there was only 5 months of 1962 production that is why there is only a small amount of C0NN Trans.'s around versus the C3NN Trans. which had a three year 1963-1965 plus warranty and over the parts counter sales) they were not sold as 1963 tractors until Jan. of 1963 , it is the same as Ford selling the the 1963 1/2 Galaxie 500 not a 1964 Galaxie 500 or the 1964 1/2 Mustang not a 1965 Mustang that's the way they did it back then not the way they do it today where they sell cars 2014 cars in 2013 . Just as in Mid Year 1954 Ford brought out the 600 / 800 tractors during NAA production and sold them as 1954 tractors not 1955 tractors . Thanks Tony

Read Sean's first post again. I think you're still confusing a part number

and its meaning with the casting number.

Other than that I can't help much. I bought my first SOS last fall.

It does seem that I heard something about a different shape in the case,

might find something on that in the archives too.

Hello Royse , It does not make any difference between Part Numbers and Casting Numbers they both are identified the same way . The prefix c0nn means 1960 tractor , c3nn means 1963 tractor , b9nn means 1959 tractor NN is always tractor the first two are the year always . 7006 is transmission in car , truck , tractor it makes no difference . 6015 is engine block in car , truck , tractor it is always engine block . Example D2NL6015J IS A 1972 INDUSTRIAL 172 4 CYLINDER ENGINE BLOCK CASTING NUMBER . Thanks Tony

Tony, You have a lot of knowledge, and have helped me and many others, but I think you've got the information about the casting codes incorrect. If a casting code of C0NN means a 1960 tractor, then why do the 1962 S-O-S tractors have a casting code of C0NN on their transmissions? Shouldn't the casting coed on those be C2NN then? You just got through explaining that the C0NN transmissions were used on 1962 tractors didn't you?
My 1973 4000 has casting codes of various years and even a couple of different decades on all of the different major components. My transmission, which has the same 1973 serial number and production code stamped into it as the number on the foil sticker under the hood, has a C7NN casting code, while my engine has a D0NN casting code, yet my tractor is a 1973, and the transmission and engine are both original. The production codes stamped into every major component match the numbers on the foil sticker, yet the casting codes on the various components indicate different years.

I have seen explanations on the web from former Ford engineers that the first 2 characters in the casting codes designate the decade and year within that decade that a particular casting was designed, not when a particular machine was made or when a particular part was cast. A particular casting design might have been used for many years in a row, so it will show up as the same casting number on machines of many different years.

Hello Sean , Thank You , but the casting number and part number info is correct . The C0NN code was used because there was no update or revision until after 1962 . There could be some C2NN codes on other parts less visible then the common blocks , trans. , rear axles we speak of most often but every piece has a casting number(there is C0NN, C3NN, &C5NN casting on Sherman parts)Yes C0NN codes are on the 1962 Blue and Gray tractors but not the Red and Gray ones . If you look at the 310835 and 310837 4 speed and 5 speed trans. cases for the 01 series tractors there is no change from 1958 - 1965 , yet 801 rear axle center housings go from 310363 to 312480 to C0NN4024F , and I know the 310 to 312 was a Metal change from Pearlitic to a Malleable Steel as were 24" wheel centers going from 311701 to a B9NN1036A casting number were steel related because of cracking problems as were the rear axle housings . Casting numbers changed when a casting was revised or updated for some reason . Sometimes the revision was the same year as the original casting or not until two or three years later , so sometimes the prefix changes and sometimes only the suffix changes . Example the C0NN7006B DDC Trans. case has no drain underneath the case but C3NN7006B does have a drain plug under the case , without having all of the original Ford Blueprints I don't know of any other differences but there may be . Example B9NN6015B Block gas or diesel 1959 tractor factory installed spin oil filter adapter , C0NN6015C block gas or diesel 1960 tractor factory installed spin on oil filter adapter , C0NN6015J Block gas or diesel block is now cast for spin on oil filter and used past the end of tractor production in Dec. 1965 . Finally the rest of what you said is also correct which is just what I trying to explain . Thanks Tony
