Transmission Issue, Don't get excited, its the A140E Options

Real quick...Figure i'd get some second opinions here. Noticed a strange clunk noise coming from my driver side when I accelerate (not only from stop, but while cruising). I thought I narrowed it down to a bad inner CV joint, but upon inspection the boot was fine, and when pressing in it while rotating the shaft I didn't feel anything "abnormal". What I did notice was a fair bit of play from where the shaft mates to the differential. Up, down, in and out..there was a lot of slop. I decided to check the diff fluid and about an ounce came out, needless to say I have a real slow leak somewhere...on to the subject. Replace the diff or the whole trans?
I realize it would be a good time to swap to a manual, but I'm missing a few parts and really don't have the time to do that now.
Thanks!

Well that was fun. I managed to get a a140e transmission from a local source for a great price. I pulled the old (in this case the one I swapped out) differential out and slapped the picked up one in. First thing I did notice was the excessive backlash the old one had. I suppose it could of been shimmed or something, but thats way too much work for me. The "new" one fell into specs as far as backlash. And now I have gotten rid of my dreaded clunk noise.
All in all, pretty painful process. Had to drop subframe and raise the power steering rack up to access what I had to get to. I think removing the rack would of been more work, but would of allowed more space. Oh well, next time, right?
