Grab the old filter that we set aside earlier and a pair of side cutters. You can get a good idea of what is happening inside your tranny by inspecting the internals of the filter. While many people just throw away their filters without even thinking twice, you can learn a lot by looking at the insides! These are easy to take apart too... just use the side cutters as pliers (more or less!) and while using a twisting and pulling motion, break the two pieces apart.
