transmission ID Q

[65rivogden]

I have a 1965 riviera with a 401, and I am trying to figure out what transmission I have. Can anyone help me?

It would have come with ST 400. It is much like a TH 400, but has a variable pitch converter with a low and high stall. There should be a tag on the side that has the last 2 digits of the year and a two letter code. You can confirm what it is from the tag.
