To change the fuild and filter you have to drop the pan. Start by getting a few of the pan bolts out so you can have the fuild go to that side of the pan and let it leak out and drain into a pan. Keeping lowering the pan until most of the fuild is out and then drop the rest of the bolts to get the pan off. You will then see the filter right on the bottom. Remove and replace with a new one. You can get a filter and gasket at a local parts store. Make sure you clean the pan before you put it back on. Bolt it up tight and fill it with dex6 tranny fluid. Shold take anywhere from 6-8 quarts.
