What kind of tranny is this?

ridelikehell · #1 (**permalink**) 07-01-2005, 11:15 AM

I've got a transmission that I split from a 351W; I was "told" that it came out of a 1970 Mach 1, but I don't really know for sure. All I KNOW is that it's an automatic, and I don't know nearly enough about automatics to identify it. I've posted 4 pics of it in my album so hopefully someone can tell me what the heck it is.
Thanks all.

I think C6's had integrated bellhousings....

Maybe a C4?

Can you post a pic of the Ford engineering number? Looks like an early C4......
the engineering number will look like C4ZZ-6010-AA or some such (this number is actually a block!).

The cast iron case suggests to me it's an FMX (an evolved Cruisomatic).

Here is an id chart by pan shape that might help.

The engineering number from the side of the case is C9ZP-7008A-3 (i think)

I'll check that chart and see what I can come up with.

Thanks so far.

I'm pretty sure on the FMX. A C4 would have an aluminum case and a servo on the upper left rear. Probably isn't a performance transmission but don't throw it out, I think the Y-Block guys use parts from them to soup up their Cruisomatics.

Chuck..right on...an FMX.
C9ZP-7008-A is a 1969 Ford large car hd transmission, 3 speed.
A C3 has a round governor port on the R/S only, a C4 has them on both sides. A C3 has 13 bolts on the trans pan, a C4 11 and is a 3 pc trans (trans/bellhousing/convertor). A C6 is 2 pc (integral bellhousing) with 17 bolts on the pan. The FMX and Cruise-O-Matics (same basic trans) have 14 bolts and a cast iron case (others are alum). A Ford-O-Matic is an REALLY old 2 speed trans, 2 pc,, 14 bolt pan with 1 round governor housing on the left side.

Sounds like its a FMX...I matched up that diagram chart and that matches up to the FMX too.

427sharpe you're sure its a 1969?

If so how much should I look at asking for this tranny? I have no reason to keep it and I only bought the combo for the 351W so it's really useless to me. Any ideas on how much I could get for it; given that I really know nothing about it?

Thanks again everyone!

Not much, I'd guess < $50. A C4 would be much more valuable. As far as I know they weren't used in any performance applications, therefore not much call for them.

Sorry, Chuck

The predecessor to the FMX, the Cruiso, as pointed out are pretty much the same tranny (mainly a valve body upgrade) was used in a REAL performance application. It was the trans used in automatic Thunderbolts of the mid sixties. They were the Lincoln version (more clutches) with a revised valve body, I think that would definetly qualify as a performance application. They have,however, fallen by the wayside as the others have been developed (the inner workings of an AOD were derived from the FMX though) and don't command much attention or money.

Yes, sure it's a 69. the engineering number breaks that out for you...C=1960, 9= 1969. So C4=1964, C5 1965 etc...
B4=1954, D6=1976 and on....the next letters (ZP) tell you who made it and for what...Z=foundry and P=large Ford. The 4 digits after are assigned to specfic parts, 1000=wheels and chassis, 6000 are engine parts, 7000 drivetrain, etc... A '7008' is an FMX transmission, a '6010' is a block. The last letters are design changes...'A' is for the original design, B the first change, C the second, AA the 27th, etc....A really neat and orderly parts system.
The FMX is not really a good performance choice per se, due to WEIGHT...but they are bullet proof when built right. For a Cobra, find a good performance C4 and get the best of both worlds, reliability and light weight. Avoid standrad rebuilt C4's, the bands are incredibly weak and one day you will want to go for a drive and the shift lever wont come out of park.....

Thanks everyone for the help.

427sharpe your info has been great...

I've got a quick question regarding these casting numbers however,

The engine that came with this tranny is a 351W with the casting number C90E-6015-B, and the heads that were on it have a D00E casting number...
I'm just confused on how a 1969 car can have a '69 block, but with 1970 heads? Were these actually manufactured like that? or were the heads more likely swapped later on?

Thanks again.

427sharpe · #13 (**permalink**) 07-01-2005, 11:15 PM

It could not have come like that...just because a block is mfg in 1969 doesn't mean it will assemble in 1969...one good instance, a block mfg in Sept of 1969 will wear a C9 date, but a head design may be current to the model year...D0, since the model year changes over in August, the C9 block may very well end up in a 1970 car with 1970 heads. Now, this cannot be reversed....a D0 casting CANNOT be original to a 1969 car, so your heads had been swapped at some point.

I thought you said it was a '70 mustang?

In that case it all jives right?

The numbers we are looking at are casting numbers, which are like a design revision. There are also casting dates which usually (at least for engines) should be within a month or so earlier than the build date of the car to be "numbers matching".

There also may have been a small aluminum tag under the coil bracket of this motor? There is a production date on the lower left of that tag.

All the date codes are a number, a letter, and a number. You might see 0L13 which is 1970 (0), L = November, 13 = 13th day of the month.

The casting date on the heads will be under the valve covers I believe. The casting date on the block is (I think) right above the casting number near the pan rail?

Probably more than you care to know... but I pulled out a ford shop tips that announced the '70 model cars. You could get a 351 2barrel with an FMX in a '70 mustang.

On the vin tag of the car this combo would have been engine H and trans code X.

I agree with Mr. Sharpe, there is no reason you couldn't run the FMX in your cobra if you want. It's a bit heavier but it should live a long healthy life in a light car like a cobra, even if you wail on it some.
