To change confrim the ATF has not been changed yet, my local dealer say it doesn't need doing as BMW say it's for life ???

currently looking for a independent specialist to carry this out. I think the oil is around £500 and two hours work.

As there are no fault code on the car I think the best way forward is to change the oil as I'm sure this is the issue as it only happens when warm so the properties of the oil at high temps are effecting the boxes operation. it does happen quicker in the journey if the car is in charge mode at the EV motor heats the box up quite clear under charge.

its better to bit the bullet, rather then spending more time with the dealer for them to try and diagnose this issue at their hourly rate. The cost of the oil change would be 6hours investigation.

When 330e transitions between ICE and EV, do u feel/see ZF 8AT shifting up/down?

My guess is that PHEV induces more gear shifts, hence the AT fluid gets more stressed overtime than pure ICE.

shifting is as normal, the shudder is only when you put additional load through the box, like when going for an overtake. or semi hard acceleration. (but before kickdown)

[bavarianride]

For those changing ZF 8AT, do pay attention to @5:50 for draining F30's transmission oil cooler(which should be done first).

here is a link to the service kit.

for reference I've had my 330e from 900 miles, now at 100k. this issue has only happed in the last two week and prior to this no problems at all.

I wouldn't say is always thrash the car but do on accession have a spirited ride.

Only need to last 6 months, until my replacement is delivered. But I cant have the car letting me down as I travel across the UK.

ZF has a service center @Nottingham, does it offer ZF 8AT fluid service for passenger car?

[rm56well]

it's only an office. and I think it's for rail equipment

[nuts about BMW]

Hi all

I bought a 330e last month. I have had many BMWs and this one is everything I wanted it to be, but I experienced the same fault on the way home from the car sales garage where I nought it. It's a 2018 with 106k miles, main dealer serviced. I find this harsh shudder occurs only in 6th gear, and between 1500 and 2300 revs when under acceleration. The fault only occurs when the car is very thoroughly warmed up.

The car is under warranty from the garage. As I live a distance from where I bought it, the trader agreed for me to take it to a local independent garage to have the gear box oil changed, thinking was a sensible first step. I am disappointed to say it isn't fixed. The trader is considering how to proceed.

Has anyone else who has experienced this issue had the problem resolved?

I think it sort of depends on what your asking of the car. When driving EV in eco pro and you floor it. Then i believe the car could switch down a gear to have a better rpm for the ICE. But i am not 100% sure of this.

I think the electro motor is also cooled with the transmission oil. So my guess would be that the temperature in our transmission could be higher then usual.

Hi nuts, sounds exactly the same issue as mine.

There are no issues. in all the same scenarios to get this to happen.. For the first hour of driving. so leads it to be a temperature issue.

does anyone know if there is a way to see the gear box temp from the hidden menus on Speedo cluster?

[nuts about BMW]

I agree it seems to be a temperature issue as the gearbox runs fine for the first half hour, but then the problem occurs when fully warmed up.

I am tempted to get the transmission oil cooler replaced. My thinking is that after 100k miles or so the oil is degraded, the cooler begins to clog so cannot operate efficiently, and the flow becomes restrictive, thus the oil temperature rises beyond optimum. Any further thoughts?

[rm56well]

do you know where the oil cooler is on the car, might be worth checking to see if it's coils are damaged, in not I would suggest removing and cleaning (flushing out).

you mentioned the garage changed the oil do you know if they changed the pan and filter at the same time, ?

I datalogged my car with Bimmerlink today. Transmission temperature never got above 78C and it was still doing it in 6th. Not sure this theory holds water. Surely there would a light on the dash if it was overheating.

Just wondering if anyone made any further progress on this issue?

Hi 330ed have you fixed this issue? Would like to chat you on what's app about it as I am chasing down the same problem and I'm based in Dublin also

I am having exactly the same issue with the same car on the same mileage!

i just bought my dream car, a 172 330e m sport with all the bells and whistles, it runs like a dream except for this shudder in 6th gear.

same as you:
103k miles on the clock
full bmw service history
Happens in 6th gear
violent shudder through 160-2200 rpm range with semi hard acceleration that dissapears when you push through it.
i can actually hold on to the shudder for up to 4 seconds if i try!

i have it booked into a gear box specialist, the dealer i bought it from said they had 3 other 330es with the same issue. they said they will cover it.

there was me thinking i was being sensible staying away from diesels!

Hi be interested to know how you get on and what exactly is wrong with the gear box. I'm having the same issues as you right now be chasing it down for months

[heifetz17]

I'm also having a similar issue so it isn't just the e models. I'm at 90k miles, fluid was flushed at 68k. I noticed it after all my bolt ons and tune/trans tune. Occasionally upon spirited acceleration I'll notice this shutter, so to speak. Almost the sensation as if the wheels were slipping on some gravel. I have an inspection scheduled next month and they're going to check the trans and drive train and I'll report back if there's any findings. Otherwise no issues and the car drives and shifts beautifully.

Interesting to hear your findings I was told I would probably need a new transmission and another garage said it could be the metatronics

[Fyodor]

Hi someone figured it?

[heifetz17]

Update: my issue has been more pronounced lately and finally today I got a drivetrain malfunction and cylinder 1 misfire upon heavy acceleration. I swapped my coils around and the misfire followed, so I'll be replacing the coils.

I suppose this whole time what I've been feeling may have been a coil getting weak and causing a mild misfire at high rpm. I'll report back after changing the coils next weekend if this issue is still present.
