I would say you have a problem in the hydrastatic transmission itself,and that could be a number of different things and hard for you to fix yourself,it would be best to have professionally checked out.

I have a 42 inch craftmas mower and the fluid is leaking from the hydrastatic area, can I replace it with transmission fluid.

If you transaxle is leaking badly adding oil may not help long term,if you remove the back hitch plate there is a allen wrench plug or a rubber vent hose, you can add oil there,measure down from the top of transaxle and fill to within 1.5 inch of the top,always allow 1.5 in of air space in top to allow for expansion. Add amsoil or mobil 1 synthetic motor oil 15w-50 or 20w-50. Do not use transmission fluid or hydraulic oil.

Far as I know the warranties are not transferable. Some hydrastatic transmission fluid can be checked by removing the battery and underneath there is a place to put the fluid and to check it. But not all models or makes gives you this option.
