Looking for part number 2204359, which would be a 20 tooth speedo pinion for a 1962 up automatic transmission. Next choice would be a p/n 2204360, which is a 21 tooth pinion. Anyone can help, please reply privately at: <mailto:crossram@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx> crossram@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx By the way, only way to identify the number of teeth is by either counting them, or by looking with a magnifying glass at the top of the plastic gear for numerals identifying the number of teeth (20 = 20 teeth). I have found that the color coding indicated in the parts book (specific color plastic for specific tooth count) is for the birds and not to be depended on. However, if you really want to know, the 20 tooth unit is SUPPOSED to be green, and the 21 tooth unit is supposed to be gray .
