    Ford oil change mileage.

    After several rentals, I noticed the transmission of short wheelbase non tow package expeditions generally performed better than my private max with the tow package.

    Not too happy with 2024 Expedition

    Here are the three things my dealership found on the valve body: 1. The oring seal inside E cluch piston is torn; 2. Scoring in valve body bores; 3. A clutch valve sticking "THER MOST" (thermostat?);

    Not too happy with 2024 Expedition

    My 2024 had the same symptom, harsh downshift from 5 to 3, sometimes 5 to 4. After dealer replaced the valve body, it behaves better now. However, I feel it comes back occasionally when transmission temp reaches 200F above. Anyway, it is still much better than before. Before the valve body...

    Missing Front Skid Plate???

    Insane. I can guarantee you this specific plate costs Ford less than 600 RMB (abt $80 USD) per piece from a factory in southeast China.

    Harsh downshift after rebuild

    10R80's valve body is a mystery. I would suggest going back to dealership and get that checked.

    5 to 3 harsh downshift only after warmed up is fixed after dealer replacing the valve body

    Flying Wrenches's youtube video metioned the MSRP of Valve Body was increased sometime early this year. Hopefully it comes with some upgrades too like the new CDF drum and outer shell.

    5 to 3 harsh downshift only after warmed up is fixed after dealer replacing the valve body

    2024 max XLT with heavy duty tow pkg and 3.73 axle. Specially thank Ted Britt Ford@Chantilly, Virginia. They don't mind if it's a warranty work or not. They just get things done. It's hard for me to find such a professional dealership nowadays. Dealership tech has three findings: 1. The oring...

    Cost to do trans filter service?

    The tranny flush service takes about $680 here in Northern Virginia. You may negotiate a little discount if you have good relations with them.

    Transmission Reset TCM Reset

    This is obviously an TSB issue. Something is going on hardware level. Software reset can't fix it. I deactivated TCM self learning feature for at least three time so far. Each time, transmission worked even worse than when I kept the self learning feature on. So I just leave it on.

    New owner with questions

    I don't understand here. Smaller rims just make the sway problem worse. If you do not do offroading, you don't have to replace the 22 rims. 9k is too much for CDF drum issue. Usually dealerships charge 3k to 5k for CDF replacement. You can get a brand new transmission with 9k. If I were you, I...

    Yes, I am right. lol. I've replaced mine early last year and it's night and day difference for the problem you described. Thank me later. lol As for the front bar, my personal feeling, you do not have to replace the front unless you like driving violently. Front bar improves the stability when...

    I have nothing to do with the Hellwig company. Just a nickname here.

    Concern 1 is absolutely factory rear sway bar problem. Just replace it with Hellwig product, and problem is solved.

    Does Ford Performance Tune void ESP coverage?

    Someone on Bronco forum emailed Ford and got an unclear response. My translation of that Ford's email: Most likely FP tune doesn't affect ESP coverage if it is installed by a dealership, but it depends on how dealership works on the claim paperwork when you have to use ESP.

    Does Ford Performance Tune void ESP coverage?

    M-9603-EN35 can increase horsepower and torque for 2022 to 2024 expedition. It definitely affects the engine block, turbos and the transmission. Ford Performance warranty only covers 3yrs/36k and it starts from the day when vehicle is purchased. Say, if the transmission fails in a couple of...

    Temperature gauge behaviour

    Thank you! This important feature was deleted by Ford soon after. I had to purchase an UltraGauge device to read my tranny temp on real time.

    Temperature gauge behaviour

    How could your vehicle show operating temperature of transmission? Is the model year 2018 or even before?

    Temperature gauge behaviour

    Look the new engine still goes with the old thermostat. I agree. 230F still seems higher than normal. Perhaps it is caused by dealership not using the upgraded thermostat (RT1252) for model year 2022 and afterwards. I replaced mine with RT1258 and engine operating temp fluctuates from 176F to...

    Maintenance and small upgrade.

    Does this kind of modification void manufacture warranty and/or service contract on transmission?

    Complete newbie looking for 40k Expedition - tell me what I should know?

    I just checked my order sheet. My vehicle is XLT with 202A. But it doesn't have moon roof. I guess it is a standalone option and I didn't order it.

    Complete newbie looking for 40k Expedition - tell me what I should know?

    If you do long road trips and camping, the extra cargo space would be useful.
