Curious if anyone with a manual trans has had this issue. It happens about once a month in our AWD Clubman S. In second, normally going down a slight incline and bam - trans pops out of 2nd gear. Had it happen to me the other night, put it back in gear and bam, happened again. Car nearing end of its warranty and will bring in, but thought I would check here.

 

Haven't experience that (yet).

From some clever googling it looks like some others have experience the issue: https://www.northamericanmotoring.co...ion-issue.html . Usual result was to replace the transmission. Kinda curious what year is your F54 All4?

And knock on wood it doesn't happen to me . I've got another year on the warranty still, but do plan to keep this car for a long long while...All4 with manual transmission isn't available anymore and I'd rather not have to hunt down a used one...

 

Thank you!
Our car is a 2018. I expected the dealer to give me crap, so I actually had my son make a video!
Car Popping out of 2nd gear

 

Oof yeah that looks not-fun. How many miles on the 2018? Mine has 20k miles and so far no problems. Although, we don't exactly have hills here in Iowa...

Reading the other thread it sounds like they tend to go with quite low miles though (3k miles sure does sound like something wrong from the factory, not something wear-like). Reading that thread carefully though, I think I have had some occasional issues when shifting quickly into second gear (clutch pedal fully down, gear would grind slightly, once or twice...I guess there is a 'clutch delay valve' that may contribute to this problem, but who knows).

Anyway I'm quite curious to know what a transmission replacement would actually cost. I've still got 1 year and 30,000 miles of factory warranty left, but would be interesting to know what I'm looking at, if the unfortunate thing should happen to me. Finding another AWD manual transmission vehicle does not sound appealing to me.

 

I have a 2017 manual with 66k miles and no problems. I did the recommended transmission service at 60k miles and am happy with the tranny and clutch so far. If I ever have to replace this car (I like manuals too) , I would get a 2019 JCW clubman S all 4. That is the last year you could get a manual.

 

Car has 30K
My son has reported this issue for two years - he is mad we did not believe him. The key is you have to be going down hill. We never put two and two together on that and if you think Iowa is flat, man, Illinois is worse My service contact at the dealer is back tomorrow - he has always worked with me so I'm praying that there will not be an issue. My only REAL worry is that this was a BMW corporate car and I think the in service date was January and HOPE it was not December...

 

Car went in today and of course they could not duplicate. They did find a damaged motor mount which they replaced. My son says he is not able to get it to pop out of 2nd now - so we shall see!

 

'Twould be really interesting if the transmission issues are caused by our rather notorious motor mounts...I'm going to guess it was the passenger side mount, closes to the passenger cabin? Seems to be 'the one' that goes bad for everyone in the Gen 3 cars.

 

yes, that was the one.

except it is doing it again. 10 days till warranty is up. Back to the dealer today.

 

Well, this time, the video of it happening was enough. Transmission ordered. I'm going to have them put a clutch in too (at my cost).

 

also having this problem on our ‘17 Clubman s all4. We are at 60k, and I’ve noticed when it’s really cold that our second gear shift has a slight crunch, but only for one shift and it seems to warm up after that. I had it pop out of second gear going downhill only once right out of our driveway but was unable to replicate it.

here’s the big question, can an all4 bell housing be compatible with a front drive transmission? I ask because a front drive six speed is half the price, and as long as final drive ratios are the same, it wouldn’t be a lot of work to adapt. Thoughts?

 

I have a 2019 clubman jcw and the same happening to me too. 2nd is tricky not to grind. Have to really put a pause in before shifting after depressing clutch. I keep thinking the synchros are gone, but maybe a device to force slower shifts. Also getting 2nd gear to pop out but haven't noticed if it's on hills or just random. I'll try to get a video as well. Don't want to swap tyranny but if that's what it takes. Maybe warranty would cover it

 

Warranty did cover it - I paid for the clutch - which I wish I had just signed up for the extended service plan that would have covered that. I now have that plan however (too late).

Car has been perfect ever since (although the clutch pedal felt funny for a while).

 

So my manual was replaced at 22k miles in Dec 2022. It was good for about 18 months and got the same issue with 2nd gear. Seems they fixed the symptom but didn't address the root cause.
My guess is there is something not right with the Getrag trans in these Mini's. Looking up part # information it seems BMW / Mini has discontinued the original manual in these vehicles and have replaced it with a new part #.
Old part: 23008672172 (GS6X60BA – YAC)
New Part: 23008672175 ( GS6X60BA – TYAC)
Looks like my dealership installed the old one even though the work invoice listed the new part #. My guess is they still had old ones on the shelf and wanted to get those out first before servicing the new part #.
I'm guessing if BMW / Mini changed the part number with that transmission, it must have been to all these issues with the shifting.

 

I don't believe the F54s had the Getrag. The unit is a Aisan box that is also used in the Lotus Evora....

 

The Automatics were Aisin I believe, but the manuals were from Getrag.
I'm pulling info from RealOEM and ChatGPT (Copilot)
RealOEM.com - Online BMW Parts Catalog

 

AI is not always correct....see this article as it applies to the F54. Also, your info comes from 2016 which is when the F54 was 1st was built. It was likely not widely publicized at that time about the transmission. It's correct only for all other Minis.

 

There is some confusion there. I definitely have a GS6, and not a BG6, in my car as I have checked the label on the transmission.
RealOEM does not mention that the F54 ALL4 variants had a BG6 trans from Aisin. Mine is a 2019. Maybe some model years got a different one. But still conflicts with RealOEM, as they only list getrag manuals for other model years.
Lotus Evora was RWD. The BG6 was seemingly a FWD 6-sp manual according to Aisin's website.
High Torque Capacity FWD 6-speed Manual Transmission (BG6) - AISIN World Corp. of America
List of Aisin transmissions - Wikipedia - wiki only has the toyota, mitsu, and lotus listed for that BG6 transmission and not Mini.
That article from MotoringFile is a little confusing to me as I thought all F54 JCW's were AWD (All4). I'm not aware of FWD JCWs in clubman and countryman's.

Did Aisin perhaps build the transmissions for Getrag? that would seem strange if that were so. But who knows. Magna was also buying out getrag sometime around all of that.

 

Definitely a mix of information, good and bad. Based on the description in the Motoringfile article, I believe I have the Aisin transmission based on the way it shifts. I've always thought it to be the weakest part of the car. I've not ID'd the trans like you did, but might look into that....

As far as the Evora, it is a mid-mounted, transverse engined car so it's possible they could have re-purposed the transmission or had Aisin modify it for their use. Just a thought....
