This is what needed to be done, the washer was against the bottom of the unit and I think that was where it was leaking from. Either way I picked up a Sioux Chief 2" non caulk drain at home depot and put it in. It said to use silicone under the lip between the drain and the inside of the shower but I've read other things that said to use plumbers putty so thats what I did (used putty that is). Huge PITA to pull the pipe down from the bottom and get it into the new since there was almost no play in the drain. In fact it appears it angles UP as it meats the main drain which explains why the water in that drain is always so high. The top of the drain is at least higher then the hi point on the way to the main drain so it should be ok. If I ever have to do this again though I think I may just cut the drain and put a new one in that's angled correctly. I ran cold water in the shower for about 15 - 20 minutes and didn't notice anything leaking, at least not obviously.
Once I finished that I took my cordless drill and a 3/4" spade bit and removed a little more wood from around the drain just to make sure that if it does leak again it will not drip on the subfloor and instead just to the basement floor (or a ceiling if I put one in...still better then the subfloor). Once I made the hole bigger I used a solution of 1/4c bleach and 2 1/2c water in a squirt bottle and coated all the wood and the floor where it was dripping with that. Also used the same solution to wipe down my tools and drill. I forgot a respirator and coughed/sneezed out some black gunk a couple times but I'm sure I'll be fine. It was leaking maybe 1/4 cup of water every 5 minutes in the shower so it was really noticeable before. I'll check it again after showering tonight but I think it's good.
