Ford Mondeo Powershift problem...

Recommended Posts

I have 2018 Mondeo 2.0 Diesel (150 Hp) with automatic gearbox and it started to have issues around 150000 km. According to Ford service, problem relates to EGR valve and when that is not functioning properly it somehow reflects to gears in lower speeds. Over 80 kmh it stops working completely. So they said that nothing wrong with gearbox, but EGR valve needs to be changed. Gears are hopping up and low when you go from lights for example but then steady drive at 40-50 kmh, no issues.

This is a really old post, post a new topic and include the transmission spec please

Sami, what are you actually asking - as your dealer say's it COULD BE the egr valve. See my post in this thread on page 1 dated Feb 2nd 2020.

As DaveT70 suggests - you need to post up a new topic with full details

Has the transmission had the correct oil and filter changes - every 3 years or 37,500 miles (60,00 km) whichever occurs first

Dear friends.

I have also ford mondeo MK4 2014 year 2.0 diesel 163 hp automatic powershift 6 speed transmission that I bought it from Germany from a private person who has changed the car's engine and gearbox that was under warranty (the gearbox is actually rebuild with less than 10000km passed after the rebuild)

I have driven the car from Germany to my living place, so it is driven already few thousand km. 

When the car is still cold, the gearbox shifts perfectly, but when the car warmes up, the powerbox starts to change strange from 3rd into 4th gear (and I think also from 5th into 6th gear). It is like it hesitates when to change especially if you are pressing the gas pedal more. Sometimes it gets the "transmission limited function" and gets into limp mode with engine reduced power and then the 1st, 3rd and 5th gear don't work. 

If I restart the car, the gearbox is working agan with all the gears, but you can still feel the banging harsh changing on 3rd into 4th gear and 5th into 6th gear if you pres the gas pedal more. 

I have also noticed that if I keep the 3rd gear under constant gas, the rpm arrow goes up and down for few hundred rpms. If I drive like that in 2nd 4th or 6th gear for example, the rpm is steady. 

I got into the mechanic who read the code problem that was saying that the pressure control solenoid C got stuck off, and changed the whole mechatronic, and tested the car, but the problem was still there. So he returned back the old mechatronic saying that it works good. (So he won't have to charge me around 1000€ for nothing)

He changed the oil and the filter of the tans box and he said that the old oil was black (I asked for the old filter to check if there are some plastic debris, but as I saw, the filter was having no plastic peaces). The mechanic said that maybe the mechanical part of the transmission is having issues, but he is not willing to take a risk to open it and suggest that I find other gearbox. 

Can anybody tell me their professional opinion if possible what might be the problem and how to fix it because I don't believe that the gearbox can be faulty after less than 10000km of rebuild (unless if was done by some inexperienced mechanic)

I wouldn't like to spend another 2-3 thousand euros for other gearbox (second hand of course) because the brand new ones I hear are too damn expensive.

If any of you have similar experience Please any advice would be appreciated 🙏

Hi. Sorry to ask this, but do you have evidence that the gearbox was actually rebuilt less than 10, 000 km ago?

Hello Alan.

Yes I have an invoice for the rebuilt that the previous owner gave it to me.

There's a big difference between the mechatronics and the shift solenoids.

Because the fluid hasn't been changed regularly, the solenoids are clogged up.

Remove and clean the solenoids, change the oil and filter, reset the adaptive shift learning

Dave, how can you say "Because the fluid hasn't been changed regularly, the solenoids are clogged up." How do you know that for certain.

In any event iIt has only done 10,000kms since a rebuild/recon - clearly the job was not done correctly - end off - needs a full strip and rebuild as required by someone who knows what they are doing - and they are like flying pigs

Thanks for your suggestions. You say that the job wasn't done correctly, so does it worth to get it to a good mechanic to remake it, or perhaps I should look for other one better? 

Could it be the problem in some of the sensors example MAF sensor, cause I have read that this can also cause these rpm variations...  Just saying what I have read so far....

According to the code, you only need to be looking at the solenoids, they will be clogged or faulty, try that they are clogged first, if cleaning them fails, change the faulty ones

Sounds so easy to do Dave, ha ha

My same interpretation still applies - clogged or faulty = In any event it has only done 10,000kms since a rebuild/recon - clearly the job was not done correctly

For the record, I do have admiration and respect for anyone who can recon one of these transmissions correctly

There is lots of info if you spend hours of trawling the net - I learnt loads of good info off I guy I had contact with in Sweden. things like DO NOT USE RECONDITIONED FRONT CLUTCHES (which even Ford dealers can and do supply)

The rebuild on this would've been a new mechatronics and clutch, because that's what they always presume is wrong. But the solenoids are also faulty, well, at least one

Dave, how can you say what the rebuild consisted of unless you were "on it". Who knows what quality of a job it was - clearly not good enough, only 10K kilometres = 6,250 miles in round figures

I have noticed that when keeping the gas pedal constant on the 3rd gear, the rpms are going up down a bit, and that I believe is causing the problem to occur  the limiting transmission function. However, i have driven the car for some time after the oil change, the rpm variations on the 3rd gear are still here, but no transmission limited function has occurred so far... 

I have been reading multiple experiences with this transmission and I also agree that fixing these hell trans is really difficult job for everyone. 

Here for example in my city and country, no one is willing to do it...

I guess I will see when I will go in Poland-Germany the next time to check there with an authorised and experienced mechanics to see the transmission and finally reveal the true issue and then see if it is worthy fixing it, or just replace the transmission with another (second hand). Because the brand new ones are still quite expensive I think 🤔  And really, I have no other complaints about this car, the engine is just perfect, everything works just great. Too bad that I didn't know this before so I could just look for manual one ☺️ but I think that this can be fixed for some small amount of money 🤑

Volvo use the same Getrag 6DCT450 transmission in some of their models.

You may get help from a Vovo dealer or Volvo Specialist
