Original stamping?

[dechev]

Hope I can get an opinion as to whether or not the following item on ebay, a muncie item# 230215310614 is a restamp or not. Thank you

That transmission is September of 1969, making it a 1970 transmission, not an early 1969 as listed. The stamp on that case is P9P10 P= Muncie, 9=1969, P= September, 10= 10th. Here is a 69 stamp comparison from a Camaro Muncie that I recently sold. I don't know why that transmission listed isn't stamped "C" for M22, as it should being a 1970 trans.

P9P10 Muncie build decodes as...

P---Muncie assembly plant
9---1969 model year
P---Sept.
10--10th day of Sept.
This is an early build trans, Sept. 10th of 1968 for use in a 1969 model year car...
It has no A-B-C ratio designator because that didn't start until the end of Sept. 1968 calendar year, a little more than a month later... Hope this helps... Crash

That's a common decoding mistake with Muncies. As Crash said, the number after the "P" is model year of the car and not the calendar year of the trans assembly.

Thanks for the additional information about this trans stamping. Would any of you venture an opinion as to whether the stamping is original or is it a restamp?

Looks original to me.

Thanks to all who responded to my questions. Always nice to have more information to work with and see if a person is on the right track or not.

He said "the NUMBER AFTER the "P" is model year. You decoded it perfectly above. As has been stated the 9 represents the model year vehicle this was used in , Not the calendar year it was built.

I have a Muncie with build date P9R03B, this one is Oct 69 based on the VIN derivative.

I would bet that the trans came out of a 69 camaro, since production was extended until Nov of 1969. Again camaros built in this time frame were still considered 1969 model year camaros. The VIN is what identifies the year in which it was built. The Vin most likely starts with 69xxxx or 70xxxx.

This is stamped PR14B (Muncie, Oct 14th, M21) The 702xxx VIN derivative indicates trans was built for a Norwood camaro built in late Oct of 69. http://www.yenko.net/attachments/314708-Octof69trans.jpg

1969 model year Corvette's was a 16 month production(Sept 1968 thru Dec. 1969) like 1969 Camaro's... Hope this helps... Crash
