What's missing? 727 BB

Old Tired Rebel said
There is a drum still in the case at the tailshaft but I don't know what it is. There is a lot missing. I was hoping to figure out what is gone and look for the parts to replace it. It seems like it will be easier to find another 727 for a donor or a rebuildable trans.

If the low/reverse drum were in it you wouldn't be able to see the Sprague. You can clearly see the Sprague. For an experienced torqueflite guy it wouldn't be no deal acquiring what's needed to rebuild what you have but if your not real familiar with what's what on torqueflites you might be better off getting a complete core. They made some changes down through the years and if you use incompatible parts it may bolt up but it won't work.

I forgot to ask how to tell what year the trans is?

There's a flat machined area right above the pan rail on the drivers side. There'll be 2 sets of #'s there. The 7 digit set of numbers that starts out with 2 letters such as "pk" will tell you what year it is.

Go to this link [ame]http://mymopar.com/downloads/transguide.pdf[/ame] and you can look up your trans. by those numbers
