Walter R Virginia Beach , VA December 08, 2023 Appliance: KitchenAid 5 Quart Stand Mixer KG25H7XWH4 Kitchenaid Mixer Kg25h7xwh4: Grease leaking from transmission. How to replace Transmission Housing. Replaced motor shaft seal and upgraded to metal transmission housing as recommended. Video was spot on. Actual parts replacement only took about 15 minutes, cleaning up the grease/oil that had leaked out took another 45 minutes. Would be good to specify the proper grease to use. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
