Trouble is, they won't know. Nobody there will know. The model of the automatic transmission is not relevant to anything in daily use, and the transmission itself is completely out of sight.

Google is your friend. From just a couple minutes (I'm kind'a busy) it looks like the 647 is a beefed up version of the 643.
