    Help tracing drivetrain ATF leak

    I have a 2004 Expedition 4WD with the 5.4L V8 and 183k miles. There's a drip leak from the drivetrain that collects on the crossmember and drips to the ground. It doesn't seem to be the transmission pan. I degreased the undercarriage to try to find the leak and it seems to be coming from...

    Engine sputtering with momentary Eng light flashing

    Today, I was driving my 2007 Expedition XLT 4x4 and it started sputtering/whole truck shaking like it couldn't make up its mind on gear maybe? Then the engine light started flashing. Only flashed for a few seconds and before i could pull over it stopped. Any thoughts?

    5.4 or 3.5

    I got rid of my '99 Expy and picked up an '09 a few years back, both with the 5.4L engine. Six months ago I purchased a "new to me" '17 Expy EL with a 3.5L and the turbos! I kept the '09 to haul my utility trailer and boat. While I'm mostly happy with the '17 and it's 3.5L, I mostly prefer...
