so i went and picked up my AOD from the junk yard. didnt get the transfer case because i saw a huge crack in it and decided that since i didnt need it in the first place not to even bother. but i got the tranny. its dirty as all heck with sand and whatnot on it. can i just spray it down with a hose or what is the best way to get all the dirt and grime off of it. i know its going to get dirty once its in again but i dont want dirt and whatnot falling while trying to put her in.
