Ok, and update. I have a 6ykm-y-00258537 stamp on my 700r4 above the pan. I did some digging and it's a 86 and from what I've read the 82,83,84 700r4's will burn up if the lock up isn't used since if it isn't locked up it blocks some kind of oil movement in the valve body. I read that 85 and up wont burn up if left unplugged but obviously locking up the converter drops your rpm's and increases gas mileage and should make your trans last longer. So I found a link that decodes the 6ykm to the exact car this came out of. 86 5.0 v8 "b" car wagon. here's the link which has year by year changes:

I read 82,83,84's have 27 spline and are weaker than the 85 and up 30 spline and the burning up part is an FYI-do your own research kind of thing before you run unplugged.
