I have just seen on the minimania website that it is mentioned that the oil capacity is : 5.8 quarts (5.50 liters).
So, if I understand well, it means that when you change the transmission oil by yourself, only 55% of the oil comes out ( as people says above they got about 3 quarts out ).............!!


As far as I know Mini does not tell consumers about the exact quantity.
I believe they claim ATF as 'LIFETIME' meaning you don't have to change - that I NEVER believe.


Even if you know the exact quantity, you will never extract that exact quantity by simply draining from the drain bolt because torque converter holds about 40-50% of the total.


So, putting in what you drain out is as best as you can do.


If anyone else has a better or more accurate method of filling in correct quantity after draining, please post!


It's a shame for Mini and all other manufacturers those who claim ATF as lifetime and not installing a ATF dipstick to save a few $$.

Thank you for your answer.
Even if knowing that I will only get out 40/50% of the used oil isn't really a good news

So what I do is frequent ATF change like every 20,000 miles or so.
And, amazingly, you can feel the improvement of smoother buttery shifting with only 40/50% change!

OK.
My mileage is 30.000.
I'm gonna wait a little bit more and will do the job by myself.

Yes, low miles it might not be worth it unless you are tracking or racing it.

Post No fluid from first plug

Hi all,

Not sure if anyone is going to end up seeing this but I went to drain mine today and when I took the first bolt out of the drain plug nothing came out but a single drop... Could mine be low on oil and need some extra put in when I top it up? or should nothing come out?

Also can anyone confirm is it indeed a 17mm hex?

FYI From the UK so I don't know if anything is different but I have ATF6 fluid from Febi Bilstein who said it was the right one and BMW said it was definitely ATF6 fluid for the gearbox.

Cheers

Did you remove the overflow standpipe from inside the drain hole?

Nothing comes out of the first bolt, its the plug to the overflow tube, which you must also remove.

ahh, from earlier replies I thought some came out of the first bolt too! thanks

Then when it is drained just refill with the same amount through the top bolt, sounds easy enough!

That’s assuming the trans has the correct amount of fluid to begin with. There’s a temperature range the fluid should be in when checking the fluid level. When colder it will be lower and might have been the reason you didn’t get anything out when you pulled the drain plug. If the fluid is too hot when setting the level, the transmission will actually be under filled, or overfilled if too cold.

I had just been for a 'fun' drive so it was quite warm which would explain it, thank you!

Strange, if the fluid level was correct the hot expanded fluid should have drained out more than a single drop after your fun drive.

It’s really important to have the fluid in the correct temp range when checking the fluid. If the level is set when too cold, the fluid will be condensed the trans would actually be overfilled when in the proper temp range. Too hot and you’ll end up underfilled.

On a 3rd gen car you should be able to get a trans fluid temp reading with a scan/diagnostic tool, or on your gauge display when in a diagnostic mode. Same with 2nd gens, but 1st gens need to use a thermometer in the fluid.

I tried getting my diagnostic OBD reader to work before but BMW has it locked down for the basic ones, need one better than mine I think.

It was jacked up on the left side so I could get under, possible that it was just all on one side so never came out I suppose... I will try ramps next time.

From the few drops that came out with the bolt it was dark/black so I reckon it could do with a change.

Thaks for the help

Do you need to run the engine during refill process and changing thru the gears as these instructions suggest?

So is the ATF 6 compatible redline D6 ATF 70/75w gl-4

D6 is the same but with a lower viscosity shear stable fluid which is what the newest Aisin MINI transmission recommends F56+. Will it do anything if you run JWS 3309 in the F56+, might not. It's hard to tell as it would have to be a long-term analysis.
So the Redline D6 ATF is safe to use on a third gen Mini?

Based off what it looks its close to the same, but with that lower viscosity.

Do you know what the correct temperature range is?

Just thought I would let everyone know that Aisin makes an ATF that specifically lists BMW ATF 6 (Part Number 83222355599) compatibility. I wasn't able to find any american retailers that carry it. However, you can get it imported from the UK from the Rough Trax 4x4 Website. For me the total with shipping is $88.99. The cheapest I could find 5 liters of the BMW ATF 6 is $194.80. Over $100 difference. Now I just have to decide if I want to replace my ATF every 25k or every 30k miles.

Not sure if anything changed for the newer transmissions, but 35-45 C (95-113 F) is what I've seen for the Gen 1 and 2's.

> Loosen the overflow screw using T-40 and let it drain all out if you don't want to get too messy. Or you can just remove the main drain plug using 17-mm Hex right away and expect to get messy.
> Tightening torque spec for the main drain plug is 45 NM or 33 ft.lbs
> Tightening torque spec for the overflow screw is 8 NM or 6 ft.lbs
> Tightening torque spec for the fill plug is 45 NM or 33 ft.lbs
> Manual suggests to replace the O-ring on above each plug.
Chazman have you had any issues with your transmission since you refreshed your fluid? I spoke with someone at my local Mini dealership and they said they won't even touch a car north of ~40-60,000 miles because the transmission has already gotten used to the viscosity of the transmission fluid.

TIA,

I own F55 2016 Cooper S with 21K miles - Auto. All is well, but when I accelerate up to ~ 10 mp/h and release gas pedal, I feel like car is about to shift to 2nd gear, but it can't since I stopped accelerating. So seems that the transmission keeps the car at the end of 1st gear, but not yet in 2nd. It feels like engine braking, maybe. If I keep accelerating and let the car up shift, then no aforementioned symptoms. Just wanted to find out if it is normal.

Hey ECS, a quick question:

in your initial comment in this thread, with the links to the products, I noticed that the BMW group ATF6 is about $42 per liter (about 1.057 qt), while the Redline D6 is about $12 per quart. Is the huge price difference sim0ly because one is branded as BMW Group? Is there any difference in quality or justification for spending another roughly $90 for the BMW branded fluid?

Its Genuine BMW/MINI so Its always more. See post #2 were I talk about the viscosity. The Redline stuff usually meets the rating then of course like many aftermarkets exceed the rating by adding their personal wear additives. I run redline MTL in both my MINIs and its the best stuff for the manuals.
