2021 FX4 Tranny problems STILL after CDF fix

[Soliyou]

I’ll keep ya’ posted

As far as I know, the neutral out condition is caused by valve body issues and park hydraulic circuit leak and not the CDF drum failure.

I still got a new CDF drum in the process with mine.

This is absolutely criminal that transmissions are failing in low mile conditions. Does anyone know if these problems have been resolved on 2024 Expy's or is it still ongoing?

Well, considering that the older vehicles are being rebuilt with the new parts that should be the same ones in the 2024 models, and still having issues post rebuild...

Guess we'll have to wait till more of the 2024 models have 30-50K on them to see.

This is interesting. I tried comparing transmission parts from 2020 and 2024 Expedition Limited on Tasca Parts, but no 2024 parts were listed, so I compared 2023 and 2020 and the Valve Bodies are different part numbers. Additionally some of the solenoids show as discontinued. Maybe, just maybe they are improving what (at least to me) seems to be a disastrous product quality / customer satisfaction situation.

In the meantime, I'm going to sit on the sidelines and keep my 3 existing full size SUVs.

Keep us up to date please.

Trans is “toast” according to the dealer, they’re getting approval from ford to install a crate factory remanned transmission (still under factory power train) Should know by end of week.

New crate transmission approved and on order from Ford. 3-4 weeks until install.
