if your family lives in the centre area of israel, you can go to one of the junkyards lokated at the arab village of Taibe. there are several of them on the main road (no# 444). any way, i doubt if they would let you take a transmittion apart to salvage parts. it is usualy sold as a full assembly.
or, you can ask your family to contact one of the local mechanics close to them, who deal with subaru, in advence, to try and get a used part for you.
there is one in kfar saba.
