I bought a used 400 transmission anyhow I am just getting to putting it in. When I dropped the pan to change the filter and the bolt to the filter was loose I took it out with my fingers. But my question is when I went to put it back in there is the bolt and a spacer. Well when I tighting it up the bolt gets tight but there is still room between the spacer and the trans so the filter moves up and down a bit. I am assuming this bolt that is in there is wrong and I need one that will tighten down so the filter cannot move? or is this the way it is suppose to be?
