the biggest thing I noticed was how much fluid was still in the trans after just pulling the drain plug. After taking it out I took the trans and held it over the drain pan and watched about half to 3/4 quarts of fluid come out of the back end. I took apart the case and set it in the drive way, sprayed it with degreaser, took a wire brush to the areas covered in heavy dirt and grime. high pressured it and then did it again to get it extra clean. I didnt take photos of the after but it came out nice. the gears I just wioed down the best I could. There wasnt a whole of of fliud on these after they sat out on top of a paper towel for a few hours.
