Thanks for posting. I've been thinking about doing mine for awhile but haven't had a chance to crawl under the car and figure it out. I always change the transmission and rear end oil with quality synthetics. Most people don't realize how transmissions and differentials break-in just like the engine and can create substantial amounts of metallic contamination.
