Topic: C-4 Markings/Daubs

[bryancobb]

Hi Folks,

Can anyone provide some insight (hopefully pictures) about the hand-markings or stenciling on the case of a C-4 transmission.

Specifically, my MAR 66 Metuchen C-Code convt.  There was no evidence of paint marks, etc. on the case, tail-cone, or bellhousing.  I have cleaned all 3 pieces and they look brand new, and I want to recreate the markings.

The car's history is very complete and there's no evidence the transmission has ever been replaced.  The tag is date-appropriate.

Thanks,
Bryan

Unfortunately not a '66 nor a V8, but here are some nice detail pics of a Jan '65 San Jose C4 from an I6:

Bryan,

Here are a couple of pictures of my late 65 Dearborn 289 C4.  I know it's not the same as yours, but they may help you in some way. 

I don't have the before pictures on this computer, but I replicated everything I found originally.

Thanks Charles,
Could you tell what that black rectangle says?  I can't tell in the picture.
And...  I would think these markings were applied at the transmission assembly plant and shipped fully assembled to the three car plants.  Is it reasonable to assume that all plants had similar markings on the transmission assemblies?

The challenge I've found with markings on Automatics is that the vast majority of them have been rebuilt and either stripped of marks (during cleaning of the case) swapped for another at the rebuilder (so 68-up check for the VIN) or painted with paint at the rebuilders

I would agree that most (not all) of the marks would be similar (inspector and assembler marks would vary of course) between the different plant if you compare trans from similar periods of time

Bryan, I posted below the pictures of the markings I found on my May 66 C4 w/200. I only found 3 marks. On the tail piece I found a shot of orange spray paint. I found an "OK" stamp in a dark blue. And I found a sequence of 4 numbers in dark red. I could only make the last two digits out and they were ??15. I noticed on Charles pictures his has a number stamped "4615" so maybe the same.

Thanks Dave,

You guys are great!

The black mark is a reverse 'OK'  I actually have one of the original stamps, given to me by a retired worker from the Sharonville C4 plant.

I THINK YOU BETTER POST A PICTURE OF THAT!!!!

[CharlesTurner]

It's just a regular rubber stamp, nothing fancy.

[bryancobb]

How big is the rectangle and how big is the OK?

[CharlesTurner]

Probably about 1 1/2" high.  It's the same type of stamp used on top of that 6 cyl. trans I shared pics of.

[bryancobb]

I guessed that, but I just didn't have a good reference in that picture.  It looked a lot larger that 1-1/2"

Did you see my question about AUTOLITE or FoMoCo script coil?

The black OK isn't unique to 66 Dearborn. From 68 NJ,
