    inconvenience or safety feature?

    This feature seems pretty useless on a vehicle with an auto tranny. Is there something I’m not getting?

    2019 Expy XLT halogen to led swap.

    Where are people finding Morimotos in the HB3 size (stupid choice on Ford's part, that)? I’ve looked on Amazon and on the Morimoto site and can’t find them.

    Help!! Dealership doesn’t know what’s wrong

    If the two low cylinders are next to each other, it could be the head gasket.

    Hellwig 7696 is installed on 2024 Expedition

    Just ordered a Hellwig rear bar for my Max, as we experience the wobble and want it gone. I won’t do a front bar, because stiffening up the front will increase under steer. Are upgraded links for the rear bar a necessity? If so, are there any links with heim joints? Wouldn’t be terribly hard...

    Transmission fluid change interval

    With the dealer, at least there’s a chance they’ll use the correct fluid. Places like JiffyLube, not so much. I’d bet they have one “universal” tranny fluid for all makes & models.

    Transmission fluid change interval

    It didn’t seem too different from other trans fluid changes I’ve done on modern-ish autos (not too many as I daily and prefer cars with three pedals). Sure, I wish it had a drain plug and a long dipstick & tube you could fill from the engine bay, but it’s not a bad or terribly hard job overall...

    Just who you want servicing your trans—a pimply teenager who’s watching TikToks while he does it.

    2020 Plat Max Transmission Normal Temps

    With my 180° tstat, I just drove for a little over 4 hours on hilly interstate, 75-80 mph. Tranny temp never went out of the 170°s. Not heavily loaded.

    Transmission fluid change interval

    I changed my tranny fluid out at around 70k. Followed ford tech makuloko's video. It wasn’t too bad at all. Got the fluid & filter from Rockauto, by far the cheapest place. Torque spec for the pan bolts is very low—felt light hand-tight at best. I felt they should be a bit tighter, but...

    2020 Plat Max Transmission Normal Temps

    I just filled it from the degas bottle and squeezed the hoses until it wouldn’t take any more. Started it up and let it get to op temp. It sucked a bit more in from the degas bottle, and I then topped it up again. Been fine ever since.

    2020 Plat Max Transmission Normal Temps

    I put in the 180° tstat myself. Took less than an hour, and the gallon of premixed coolant I bought at the dealer was enough to replace what was lost. My original (brass collar) tstat was sticking, causing temp spikes to over 235° on the highway, loaded but not towing. Temps are now normal and...

    new 2019 expy platinum owner - no HD towing - help with controller

    I bought a Ford trailer brake controller. The plug for it is not behind the coin holder but a little cubby, right of steering wheel and left of the center console. I tried a generic oem-style one off Amazon, but it didn't work and caused a parasitic drain. I also had to enable it with Forscan.

    Ford quietly redesigned the thermostat in 2022...replace it

    Just looked at the link you provided—I would not buy that thermostat. It’s got the brass tail piece, which on my original one would bind, causing temps to rise. Looked in my Amazon history, and there it was. Part number is RT1258, $24.

    Ford quietly redesigned the thermostat in 2022...replace it

    Yes. Original is a brass piece. Comparing the two before I installed the new one, I noticed the plastic tail piece slid smoothly. The brass piece would bind sometimes. Not sure if that was causing my higher temps (and warning on dash), but it makes sense.

    Ford quietly redesigned the thermostat in 2022...replace it

    I don’t remember exactly where I bought it, but it was not on eBay. Thinking Rock Auto or Amazon?. It's a Motorcraft part.
