I have a Muncie M20 laying around with the first letter U stamped as part of the vin# I guess. What plant is "U". Is this Pontiac or Olds??? Thx

Are you sure it's a U? I'm definitely not a Muncie expert but I believe the letters in the serial or VIN number are "P" for the 4 speed made at the Muncie plant or M for the 3 speed. Other alpha characters are for the month it was made, so they would only be the first 12 characters (A to T) of the alphabet. I found this stuff out today as I'm decoding my Muncie to get ready to sell it. Lots of info out there on the various markings. If I've stated something incorrectly someone will speak up.

U is for Lordstown, Ohio. They built full size Chevrolets and Pontiac Firebirds. We need the full VIN before we can tell you what it came out of.

Yeah Carl, there's usually 2 seperate stamped codes on a transmission case; 1) a trans code and 2) a partial VIN. Sounds like you've got the trans code down. The "U" as mentioned above, is part of the partial VIN....the plant where the car was built.

I bet you already knew that !?!....

Thanks for the replies guys. I dropped the trans off to be freshened up and will get the vin# when I get the trans back. Thx again.
