My transmission is a 2 speed auto (I've never had the car on the road, so can't even be 100% on that), but I don't know whether it is original... On this site, and in my manual it says I should see a MA code somewhere (my engine is a 326 2bbl no AC), but I can't.

Here's a picture:


I see the numbers:
67
LC190D
1372028 (and then a logo, and then a small 4)

Can anyone help with identifying this transmission?
