FORD FOCUS TRANSMISSION REVERSE

Hello I Have A 2010 Ford Focus Se And All Gears Work Except Reverse. What Might Cause This Problem?

Had Shuttering And Shaking Going On For A Week. Then All Of A Sudden, The Engine Light Came On And I Have No Reverse, But Still Drives...

I'm Having A Few Issues With My Car. The Transmission Keeps Overheating, The Horn Barely Blows, My Car Will No Longer Reverse At All...
