I am trying to find out what transmission I have. It came out of a 1969 Corvette Convertible. There was 3 numbers on the transmission not including the patent number. That 2 numbers that are on the transmission are:

392566
P00264

And the number that was on the tail-shaft was:

70S416517

Hope somebody can help me out. I cannot find anything on google as to figure out what this is.

This is the cars serial number 70S416517 but this indicates it is a 1970 car. What is the serial number on your bill of sale? do they match? Not sure about this one P00264 but I think the P is for Muncie. they didn't use a t10 in 1969 or 1970.

This is a link to a Muncie History page, with alist of the codes stamped on the transmission.
I hope this helps.

Thank You both for the help. I have some new information. I went out to the garage this morning and took some pictures of the numbers.

When I looked at the pictures I realized that the number is not "P00264" but is "P0C264" I did not see that yesterday. The "C" would be a March code correct?

I also have pictures of the other numbers I will post.

Hopefully with the rest of this information I will be able to find out what gears are in this.

EDIT: There also looks to be a "1" after the "392566".
EDIT2: The code is not "P0C264", It is "P0C26A"

That's better. P0C26A = 1970 march 26 and A = M20 ratio
