P2884 AND P2885 Engine disconnect clutch codes

[Jabkissmya]

I had these codes come up last year and after 2 months at the dealer they replaced some aux pump in the transmission. I had one come back a month ago went back to the dealer and they said it was a clear and retest code and they could not get it to duplicate, satuday it threw both codes while towing my box trailer ( these codes put you on the side of the road with powertrain failure and pull over safely displayed in the cluster ). has anyone else had these codes before and after repairs? I am not a fan of taking my truck to the dealer only to have it there for long periods of time with no solution.

Haven't seen that one but will be watching for replys.

The clutch has its own solenoid so it could be something with the clutch's feed. If a clutch is ''stuck open', it's either solenoid or something else. That clutch is fed through one of the 'tubes' in the pan of the MHT trans and uses those little rubber jumper pieces to be fed.

Let's be clear, this is a really expensive issue and I'd be raising hell w/ ford. The hybrid drive unit where that clutch resides is 'non-serviceable', and is quite expensive (covered under hybrid warranty). It's what keeps your ICE connected to the trans. At the very least they should drop the pan and inspect the valve that operates that clutch. I'd also get them to replace those rubber 'jumpers' -- forget the part number, they can fall out when the pan drops.

I can't find the old invoice, last year they replaced the aux pump and some lines. it was under the original warranty. My problem is thie is very sporatic, best I can come up with is that the drivetrain has to be "strained" for this to happen. All but one time was at highway speed in throttle. the ones time it wasn't at highway speeds was wot in the snow spinning tires. It shuts off the engine and I have whatever power left in the hv battery to get to the side of the road then truck is dead. You have to do a complete shutdown of the truck ( power off, open and close drivers door, wait for screens to go blank ) and it will start back up like normal with no more warnings on the dash.

Every time I jump in my truck, I think to myself "is today the day?" These PB's do not inspire confidence, but they sure are nice when working properly.

There's half a mil or more PBs on the road. Not every one of the is perfect, but the statistics are in your favor. There's just a very select few things to worry about and ANY issue like the above I'd rate as "serious". I've seen the end result of ignoring signs of a failing pressure circuit on the hybrid and it's a $10k bill for new OEM parts.

For less than 2 grand one can rebuild the 10r80 themselves making it an even stronger / higher reliability trans. There's just nothing that can be done for the hybrid drive unit as of yet. If I find one cheap enough I'll buy it just to tear it apart to see what can be done to it. I suspect the hybrid clutch borrows parts from the trans, and if so, then it can be rebuilt w/ GPZ parts. It's real dumb to consider the hybrid unit as non-serviceable given that it's got 3 different components in it that are all very unique parts, though I do suspect some welded attach points.

Yeah, the 10R80 really is the worst part. Mine started acting up, so I made an appointment for 3/10 to have the dealer look at. The service advisor asked me to describe the behavior/issues I'm having, and then says, "oh yeah, we replace 3-4 10R80's every week". They have 2 techs that do nothing but 10R80 replacements.

I only have 9800 miles on it, and haven't had any PB related problems, but am asking them to look at the exhaust gas heat recovery nonsense and the recall for the PCM reprogram in my app. (24N04, 24E04) as well as the parking sensors that never work and give me a warning every start up (Pre-Collision Assist not available).

Just an update, the truck started making a random spooling noise while driving at low speeds, best I can describe it sounds like one a starter bendix doesn't engage a flywheel when starting. and when it does this I feel a buzzing through the floor and accelerator pedal. It like the fault codes are sporatic and not consistent. So, we dropped it off at the dealer yesterday and I gave them a detailed report of everything I have experienced the past 2 weeks with this truck including what appears to have been some hesitant shifting from7-8 and 8-9, it would literally rev up in between shifts. Heres to hoping something can be at the minimum figured out about the fault and it shutting off in the middle of the interstate. Will let everyone know when I hear from them which probably won't be anytime soon. The wife did say she heard/felt the noise/buzzing, so hopefully they will be able to duplicate that as it has gotten worse.

Hello mate.
I would like to ask if you have solved your problem with error p2884 and p2885 because I am struggling with the same problem and I am looking for a solution. If you have some interesting information on this topic could you share it?

Dziękuję.

U mnie też po odłączeniu kilku wtyczek wszystko wraca do normy. Najgorsze jest to, że gdyby to się stało na przejeździe kolejowym, to ja bym nie przeżył?

@Piotr you shouldn't be stopping on the tracks, ever.

Also if you're too small to move a vehicle from tracks, another vehicle will do

Quick update dealer was able to duplicate shiftability issue as well, so they did the cdf bulletin and put another auxillary pump on it. and unit failed again on road test. That was yesterday, so they said the have to call ford to go futher with diag.

Thanks for the updates. I look forward to the final diagnosis and resolution. I'll keep you posted. Thanks again.

Mine died on me last year as described (engine shuts off, coast to side, restarts after a few minutes). I’m my case I went through an aux pump, the electric drive motor and eventually a new transmission/new drive motor. Well this year (few weeks ago) same thing happens. They put another aux pump in and it seems to be ok for now. Honestly I’m waiting for it to die again on me somewhere . I really hope not
