Where would you find a picture of a car or truck transmission diagram?
in Ebay ie really easy, you find anything you looking for Also, about the best supplier of info I've found is transtarindustries.com. If it's an automatic, it is most likely the 700r-4, which is a very good tranny. They have all the data + parts lists in pdf format for just about any tranny you can imagine.
