the gear selector is stuck in park , even with the engine running and the brake

thanks for the " check fuse " suggestion ..... fuse was good , turned out that the " Brake Light Switch " was defective , it was under recall by MB .... so had MB dealer replace it ..... runs good now . Once again , pushrod , thanks a lot .

Thank You , Marlene222 ..... I had the problem solved , it turned out to be the "Brake Light Switch" .
