    How to disconnect transmission lines from radiator

    I'm replacing a radiator in a Gen 2 Expy. I think this was mildly overheated at some point and so that may be affecting things. The core problem is there seems to be absolutely no way to disconnect the transmission lines into the radiator fittings. The gap between the locking ring and the...

    Transmission - Hard Downshift / Sticking and Clunking Noise

    I have a 2020 with 57k miles. Recently I've been experiencing hard downshifts, especially from 4th gear and down. It feels like it's sticking, and then releases with a clunk that I can hear. I had the software upgrade done a few months ago. Any ideas for what's causing this? Thanks!

    2020 post drivetrain warranty (63k miles) transmission shift issues - options?

    All, I have a 2020 Expedition XLT. In the past I've occasionally experienced the rough shift and two or three times we had the 'bang' that seemed to come with a large downshift (with the warning lights that went away after re-start, etc.). This is my wife's car, and I only noticed it when I...

    Transmission issues?

    Hello all. I’ve got a 2006 Expedition that recently started having what I believe are transmission issues. From 20+ mph it’ll rev up to about 4k and not accelerate any more. If I shift manually from 1st to 2nd it works fine. I then try to shit to D and same thing. We are thinking it’s the...

    Just bought a 2010 EL limited. Shudder, help.

    Hi So beginning of this month I bought a 2010 EL limited and today a mechanic told me that I have transmission problems. He said he wasn’t a transmission guy so he couldn’t be for sure. But he was pondering it could be a solenoid. It shudders when shifting and makes an intermittent groaning...

    Hello all, Thank you for accepting me. We are in the market for a 2018-2019 Navigator L or maybe an Expedition Max Platinum with probably around 55-70k miles. I have done a lot of research on these and so far anticipate for the cam phasers to go bad soon when not done yet and probably...

    Mishimoto: Has anyone done any of the upgrades? They seem to have some good stuff!

    Mishimoto, Has anyone done any of the above upgrades? I have a 2018 Expedition XLT Max tow package. I have transmission and radiator heating issues, so I thought this would be a great place to start. Or move to a truck, but we love our Expedition. And it is a lot cheaper than moving to a new...

    Transmission compatibility: 6R75 vs. 4R75E

    Are these two transmissions swappable, by chance (i.e. will an Expy 6R75 work in an F-150 King Ranch of the same model year)?

    Navigator ZF5 Manual Swap

    I'm about to embark on swapping a ZF5 into my 2003 Navigator. Bought it for cheap with a bad tranny, happen to have a donor 2001 F250 w/ V10 and a ZF5 sitting behind my shop that my wife REALLY wants me to get rid of. Figured I'd save a little money, build a fun daily driver, and give me an...

    I have a 2010 Ford Expedition Limited... When I start the vehicle, it makes a squeaking noise, not very loud, but constant. It does not appear to speed up when I rev the engine, and I don't think it speeds up when accelerating. It appears to come from the transmission, but the flex plate looks...
