I'm trying to remove the valve body to clean the screens that Todd recommended(car doesn't shift to high gear) in another post. I have the pan and filter off. I removed about 9 bolts(10mm) from the piece where the filter attaches. It looks like it's still attached to the piece in the front. The piece in the front has about 9-10 long 10mm bolts. Should I take them all off? Anyone please help
