rkestenb The way my grade brake works is when going down a hill using your grade brake each time you step on the brake it will shift to a lower gear to slow you down more. The grade brake will not let you shift low enought to over rev the engine. My grade brake has never released by putting on the brakes only when you give it gas. Hope this helps a little. Good Luck Sonny
