Antone ever heard of restamping the transmission
I was under the 63 correcting a few things and notice some numbers on the side of the transmissio case. Got closer to them and it was the vin number. Been a lot of threads about stamping blocks but what about transmissions, I have no doubt this is the real deal, First time I've ever own a car where I could proved the transmission was original to car. Love those numbers.

I was never clear on whether or not transmission stamping started at the same time that engine stamping occurred.
I seem to recall that it did not. I don't recall 1960 or 1961 C1 cars having the transmission stamped, even though the engine was.
I am also thinking that there was a difference in the time frames for stamping manual trans cars vs. automatic cars.
Somebody help me out here.

Yes there are people who restamp Muncie cases. We don't believe in it at all. There are also service replacement castings that were sold either over the counter, or used in a warranty, that were never stamped. Technically not a re-stamp in this case since the term implies removing the original stamp and replacing it

It was at some point during the 1960 production run, that Chevrolet started adding a "hidden" VIN, to the transmission cases of all transmissions installed at St. Louis. On manual trans' it was stamped by the date and trans code, while it's placement varied on automatics.
People have been restamping transmissions, as long as they've been doing blocks, at least the early 70's.

I don't know who Antone is, but I've heard of it. I know of one back in the late 80's that had a crack and the case was replaced the original gears installed and the case stamped with the vin.

I was told once that if an engine pad's VIN stamp had a certain identifiable "look" to it, it would be consistent in the trans stamp and that would be another way to check for authenticity of the car. I have not really been able to compare them on many cars so I don't know. Anyone ever hear this?
I guess a restamper could do both the pad and the trans, but I have to guess most stop at the block. Still, people are getting better and better at this.
The trans stamps on my 2 cars are pretty straightforward. Its hard for me to imagine restamping them cleanly. My pictures below... the '63 is the one with the red box to show where it is (you see the number after your eyes adjust) and I dont know how you grind off another number there and restamp it. Anyone have a photo of an actual restamped transmission VIN?

I was under my car again and you would have to be a blind man not to spot a restamp. The proplem is you loose that roughness that is part of the alum cast material when you grind or mill the number off.

I believe that most stamps are a "Gang Stamp" meaning done all at once rather than with hand set stamps. This means the numbers should be aligned or misaligned together; with the impression deeper at the top and more faint at the bottom

Identified letters please.
I think I have these numbers identified correctly but can someone check it. The letters by the vin number are WA 1731. W= Warner Gear, A=January, 17= 17th day, 3=1963, 1=First Shift, thanks

The statement about an anomaly in the engine VIN stamp also occurring in the trans VIN stamp is correct, at least in one case.
I used to own a 73 Convertible that had the last digit of the VIN of the engine over-stamped. The digit was originally an 8, then was over-stamped with a 7. The correct last digit of the VIN was a 7.
The very same over-stamp was on the automatic transmission case as well.
The was a base motor, automatic, full option convertible.
I have a picture of the engine pad with this over-stamp somewhere.
