Bill, The build date will be on the transmission's left side, along the bottom of the case, just above the tranny's oil pan. It's a stamped into the side, XXXXXXXX XXXX XXXX. The second 4-digit number will tell the date. Chrysler used a 10,000 day calender starting July 29, 1961 as 0001. I have a chart for the calender if you can get the number.
