Go under the car. On the side of the tranny just above the pan is a metal label. Clean it off with carb cleaner so you can read it. It will say something like this:
Model #03-70L
1208-604
Serial #89LK80337

The above is an AW70L (with lock up torque converter)
It was manufactured in 1989.

Keeping in mind that I know little about transmissions, per the above table you have AW40 (A341E). This is your 965, right?

By the way, any idea on how to make the above link "clickable"? ([url] and [/url] don't work on this board).
