Muncie 4 SpeedTransmission

[Don kelley]

I an trying to determine what year this transmission is:

I have a rear casting number of 852254 and a code stamp of O 3 1 could be D3 1

I am somewhat sure the D 3 1 means a April 3th of a 61 71 or 81. I am hoping my casting code will tell which of the 3 years.

Re: Muncie 4 SpeedTransmission

What is the casting number on the side of the main case? There will also be a number starting with a "P" stamped into the side of the main case toward the rear of the main case. These are the numbers you need to ID the trans, but it is not a '61, (None Built) and Muncie had ceased manufacturing after '75 or so, so it isn't an '81.

Since there were no Munices in '61 or '81, it would have to be '71.
