4 speed trans p8b14c   #18L336738

p = Muncie 4-speed transmission
8 = 1968
b = February
14 = Day of the month (Valentine's Day  Kiss)
c = M22.  This is the part that doesn't fit because this suffix code (c) was not used until October 1968 and this transmission was assembled on February 14, 1968!?   Huh   Someone might have restamped these numbers!?

18L336738 is the partial vin which the factory stamped on during assembly of the car.  How many times is this partial vin stamped on this transmission?

Do you have a picture of the stamping? Paul is correct, it shouldnt have a C after the date.

You can still get a picture of the transmission code with the transmission in the car.  The partial vin is a little tricky on Los Angeles cars because the vin is stamped on top of the transmission.  I've photographed my partial vin with the aid of a mirror, a droplight, and a steady hand; so it's not impossible.

Well I took some pics but I can't post them since I pretty much suck at using computers.I know how to post them but they are to big and I don't know how to make the file size smaller.I can send them to someone or can someone explain how to shrink the file size on the pics.

Pretty common for 68's to have the small c after the code.

What does it signify?  If I'm following the gist of this thread it would not indicate M-22 during '68

It's not really a "C". It's more of a square with the right side missing and it's smaller than the VIN font. I believe these are Inspectors stampings. There are others as well... Triangle, square, diamond, etc...

I used to have a picture of the "square c" but can't seem to find it. JohnZ? Kurt? Rich? Jerry? Tony? ANYBODY?Huh

Ed, I take it not all transmission got one of these stampings?  My trans is clean except for the P8A08.

Here is something else weird about my transmission.  It has "R-I" embossed in the case.  These letters are not engraved, they're raised.  It had to be drawn into the sand mold by somebody.  Does anyone else have this??  Huh
