    Are these symptoms of the CDF drum isue?

    Yeah unless this issue causes permanent damage to the transmission I am fine with it. As long as it runs for another 70k lol

    Are these symptoms of the CDF drum isue?

    I agree. Whenever I accelerate quite a bit, I don’t feel it as much. I definitely feel it when I don’t have enough speed and it shifts up. Are there good tunes to fix the programming ?

    Are these symptoms of the CDF drum isue?

    Here are the symptoms I have on my 2020 Ford Expy Max: - Slams into D or R - sometimes- 4->5 is rough - 7->8: used to be rough. No longer rough once I cleared the learning tables - Scariest symptom: Happened only once. I was accelerating on the highway, and heard a loud thud with the back of...

    TSB 23-2250 - 2018-2023 Expedition/Navigator + Other Models - 10R80 Auto Trans + Others - Harsh/Delayed Engagement And/Or Harsh/Delayed Shift

    So do the rough shifts from this eventually kill the transmission ? Or just make for some rough driving ? ?

    Adding Brake Controller - Gain not working

    Thank you for your detailed message. Here is how I tried it: I put up the wheels on jacks, rotated them and then got someone to hit the brake. Even though the "no trailer" message shows up in the dash, the tires stop after a while. But I am not sure if the brake pressure is being respected...

    Adding Brake Controller - Gain not working

    Sorry that is the dry weight. GVWR is 3500lbs. I am fairly certain they have brakes but can double check.

    Adding Brake Controller - Gain not working

    I bought an "OEM brake controller" from ebay. And plugged it in. Used Forscan to enable a brake controller module. It did not have the Brake Controller Gain module in Forscan. With this setup, when I plug in the trailer I get a "Trailer connected" message and I can setup the blind spot...

    OEM brake controller question - did you enable it yourself? If so I have a question (gonna make another post on it, but thought I might ask). I bought an "OEM brake controller" from ebay.

    Transmission Cooler for 2018 Expedition/Navigator 4x4

    So I've read that the optimum operating range of the 10R80 transmission on these cars is between 200-220... and they don't perform well when it is 170-180F: have heard that they get jerky below this range. How are you accounting for that?

    Towing Advice Needed

    the GVWR of the trailer is only 5500. So even in your math I have another 500left. And I think max tow for me is 6300

    Towing Advice Needed

    Fair - I am coming to the same conclusion to go for a smaller trailer. I might not go as low as 3100 dry, but end up at 3500 dry. Thanks for the suggestion!

    Towing Advice Needed

    Hi folks - I own a 2020 RWD Expedition Max, without the HD Towing package - so 6300lbs tow capacity and 1600lb payload capacity (from the label on the door jab). I've read all 4th gen threads so far as well, using the search function, but want to get y'all's feedback. I am looking at a trailer...

    2020 Expy Max: Is there a good step by step for upgrading the suspension DIY?

    Oh that is awesome. Another question - can I just start with the rear (suspension and sway bar) and do the fronts later? Would that affect ride quality?

    2020 Expy Max: Is there a good step by step for upgrading the suspension DIY?

    My 2020 Expy (which was previously a rental and so probably abused) with 65K miles has a shot suspension (see this thread). I want to take the suggestions and install: - Bilstein 5100s on the front and the rear. - Upgrade my coil springs with OEM at the same time - Add a rear hellwig sway bar...
