thanks for the reply

I contacted Hannys Honda and they can rebuild the box for $1800 or if I find a box they can fit it for $350.

checked some wreckers, Hontoys asking $700 others were asking upto $1300.

As to why the fluid was so low in the first place I have no idea, theres no physical leaks on the outside of the trany, but like you said could be leaking lines or its old fluid thats burnt up.
