I HAVE A 2014 F250 WITH THE 6.7. THE TRUCK HAS 127K MILES ON IT. I HAD THE TRANSMISSION FLUID CHANGES AT A FORD DEALER AT AROUND 100K. THEY USED THE MACHINE THAT EXCHANGES THE FLUID WITHOUT REMOVING THE PAN OR THE DRAIN PLUG. YESTERDAY, I NOTICE TRANS FLUID ON MY GARAGE FLOOR. A SMALL AMOUNT, BUT ENOUGH TO GET MY ATTENTION. I GET UNDER THE TRUCK AND NOTICE IT IS COMING FROM THE DRAIN PLUG. I CHECK TO SEE IF IT'S TIGHT AND IT WAS. I THOUGHT IT MIGHT BE OVER TIGHTENED. I BACK OFF ON THE PRESSURE A LITTLE AND THE LEAK STOPPED. TO MY KNOWLEDGE THE DRAIN HAS NEVER BEEN TOUCHED. HAS THIS HAPPEN TO ANYONE ELSE.
