New guy, here. This is a great place, by the way! Learning much. I am however, having some trouble id'ing my tranny on a beautiful 1966 F-250 Custom Cab that I just purchased. Found the id tag on the tranny, and it reads, PHB Z5... on the top line, and D40BAJ13B on the bottom line. Sure could use some info. Thanks

 

I can't decode tag's but I can count pan bolts & shapes to determine type trans on auto's. I'm sure someone alot smarter than me can decode your numbers. Post the truck vin /warranty tag info and it also can be decoded as well.
Welcome aboard.

Mitch

 

Thanks Customcab, for the welcome and the info. I am pretty sure that this tranny is a ford-o-matic, but not sure if it came with the truck as an original piece. From what I can tell from the numbers I put out, the trans is from 1974??? I didn't thind Ford used those transmissions after 68, but I could be mistaken. I would post the vin/warranty tag if there was one, but unfortunately it no longer exists on the truck. The vin is factory, but has been issued as a CA tag id. Don't have too much history on the truck.

 

Hey your local. I'm on the East side of EC. I'd be happy to stop by take a look and show you where the frame is stamped. Welcome to FTE Neighbor.

 

Welcome to FTE

It is not a Ford-O-Matic. No Ford-O-Matic's installed in trucks after 1961.

It's a transplanted FMX. These were not installed in trucks, either...except for 1973/77 F350's with the 300 I-6.

PHB-Z5 / D4OP-BA = 1974 Torino 351 FMX w/a column shift.

Parts catalog only says 351, it doesn't say if it's a 351C or 351W...both were available in 1974 Torino's.

J13B = Assembled September 13, 1973.

Info source: ID tag decoded from the 1973/79 Ford Passenger Car Parts Catalog, Section A70, Page 4.

btw: What engine does your truck have? No 351C's were installed in trucks. The 351W was first installed in F150/350's in 1981.

As original: If the VIN of your 1966 begins with: F25A = F250 2WD w/a 240 I-6 / F25B = F250 2WD w/a 300 I-6 / F25Y = F250 2WD w/a 352 2V.

352 = 5 valve cover bolt holes per side / 351W = 6 valve cover bolt holes per side / 351C = 8 valve cover bolt holes per side.

The Warranty Plate TRANS code will be the letter G if the truck originally had an A/T.

Ford confusion: Thru 1978, Ford used the letter G for ALL A/T's.

One had to know which trans came with what engine.

1965/67 F100/350's with a 352 came with the MX Cruise-O-Matic // 1965/67 F100/350's with either the 240 or 300 I-6's came with a C4.

The FMX was introduced in 1969, shares some parts with the MX....which was the Heavy Duty C-O-M, refered to back then as the BIG Cruise-O.

 

Bill, first off I would like to say thanks for all you do for everyone. Your knowledge is incredible. And thank you for the welcome. The warranty tag I assume went missing long ago, and the truck was issued a CA id tag. The vin is F25YR8805185. However, after receiving your info, I had to go and check the valve cover bolt pattern. There are 8 valve cover bolts, meaning 351C, which is what kind of motor? Is it a desireable motor? Obviously not an FE!! I re-read the trans tag and those are the correct numbers on the tag, but can't tell if they match the stamp on the trans. Possibly... Running into a few problems with kickdown and up shift, other than that, motor runs good. Thanks again

 

cobraguy, yeah I just live over by Greenfield Jr Hi. Am kinda busy til Fri, but will be in touch with you asap. thanks for "lend a hand" offer. Finding out more and more everyday. Take it easy!

 

The 351C (Cleveland) is a very good engine originally installed in 1970/74 passenger cars/Ranchero's.

Your F250 2WD (F25) 352 2V (Y) was assembled in San Jose CA (R) in June 1966.

 

351Cs come with two different heads 2V and 4V. The 2V(2 bbl carb) is an excellent all around street motor. The 4V makes more power but has less street mannners and a bigger fuel appatite. The FMX is a good trans commonly found behind a Cleavland, they say its basicly a C4 with an iron case. All I know is I've flooged a couple and they held together. I live off Washington by Granite Hills. You need a few more posts then you can PM info you don't want to share with the whole world. You can try clicking on my user ID in any post and see if it gives you the option to send me an e-mail. The option isn't available from me to you yet but I think that you have to have a number of posts before you can use them. I'm sure it is all spelled out in the forum rules.

 

The FMX is an upgraded FX C-O-M that was used 1958/67 with 292's and 332/352's in passenger cars, with 292's and I-6's in 1961/64 F100/350's).

The FMX's pan is the same as the FX C-O-M, has 14 bolt holes.

The FMX shares some parts with the FX (and MX C-O-M used in 1965/67 F100/350's and behind 390's in cars), shares next to no parts with a C4.

The C4 pan has 11 bolt holes. The MX C-O-M's pan also has 14 bolt holes, but the pan, gasket and filter are not the same as an FX or FMX.

The FMX was introduced in 1969 Passenger Cars, and was commonly seen behind the 351W (also introduced in 1969) and to a lesser degree with 302's (all passenger cars).

Some 351C's used C4's and FMX's (Torino's for the most part), most 351C's use the C6.

 

Hey, Bill, checked on the trans pan bolt configuration. I have 14 pan bolts, so I am assuming I have an FX or FMX until I can dig a little deeper. As this truck is my daily for right now, I can't pull motor or trans, but maybe this winter. Where do I look for motor ID on the 351C? Is it stamped on the block? Thanks for your help!
