i was just cleaning my tranny and t-case and was getting pretty pissed when i decided to use some easy-off oven cleaner. needless to say, i was WAY impressed. i let it sit as recomended and used a nylon bristle parts cleaning brush for the cracks and corners. no more pain in the a$$ cleaning for me. it worked better than any other engine cleaner or degreaser i have ever used. matter of fact, it worked so well, i wished i had taken before and after pics to post with this.
