c5 AM6 gearbox issue?

[michok2]

Hi Guys,

Recently I've changed oil in my AM6 (this was 5th change i will tell you later why 5th) and I'm not sure if i have a problem or I'm looking for a problem.
My car is from 2013 2.0 HDI 163 FAP with 121k miles on the clock.
I wasn't sure when was the last time gearbox oil was changed so i went for it.
I used Millers ATF SP III WS SYNTH. After 3rd change i noticed that front oil sump is leaking. I've sealed it (4th change) but i wasn't happy about my work so i drove couple of miles(1000-1500) and then i sealed it again (5th change). Now I'm happy with my work, nothing is leaking etc.

FYI - No errors are present in Diagbox on gearbox level.

Back to the chase, i have two concerns:
1. Every single time after change i removed ~40% units from oil calculator and currently im on 13373 km(or whatever units are there). I went for a drive (120 miles, driving normally) and after i plugged in diagbox again i noticed that i have still same mileage -> nothing has been added to that one -> still 13373.
what the heck?!? Did i broke something?

2. I think that my revs are bumping up during gear change a bit (100-200 revs) -> is this a normal thing?
25% throttle, slow ride:


50% throttle:


No noises are present during change, everything is smooth, just this rev bumping is the only thing.

has anyone run into the same problem?

The oil counter is supposed to be reset after changing the oil (back to zero). The autoadaptives will reset after it has been drive for a while.

Also, the oil is important. From what you have specified, this would not seem to be the correct oil!

The gearbox oil is dependent on the Euro standards for the vehicle and this affects the oil type. I would need your VIN to check the correct oil for your vehicle, but this stuff does not seem correct as it seems to be for the Euro 4 specification (JWS 3309) and your vehicle may likely need the JWS 3324. I'll have a better idea once you provide the info.

I've followed different instruction...now i've went for a full reset.
I always used Millers as my oils for everything so that was my first pick.
Vin: VF7**************[VIN obfuscated, can be read by forum staff]

oil which i used have both
Aisin Warner JWS 3309 , JWS3324

do you have any idea why my oil counter doesn't work?

Ok, so you have a Euro 5 certification and this means the gearbox should have JWS 3324 or AW1 equivalent (Not JWS 3309).

When you say your oil counter doesn't work, what do you mean? The gauge on the instrument panel or the oil counter on the diagnostic tool?

If on the diagnostic tool, you need to go into the AM6 gearbox ECU settings and find the option to reset the oil counter and set it back to 0. (This has nothing to do with miles or distance).

as i said, https://www.millersoils-shop.co.uk/mill ... -sp-iii-ws has this JWS 3324 on his list so...it's good?

If on the diagnostic tool, you need to go into the AM6 gearbox ECU settings and find the option to reset the oil counter and set it back to 0. (This has nothing to do with miles or distance).

What i meant was that "oil counter" hasn't increased after 10 miles - still shows 0 units. i went for a ride and after that one i checked Oil counter -> still shows 0.

p.s. you have a lot of oils which meet both specifications:
AISIN PREMIUM ATF 6 5L T-IV FLUID 3309 SP-III

Aisin Warmer JWS 3309, JWS 3317, AW-1.

So this Millers isn't something "special" i guess.

[GiveMeABreak]

I just meant that the JWS 3309 is specifically for Euro 4 gearboxes and not the later Euro 5 AM6 gearboxes for example. Not all the AM6 gearboxes are the same, they have multiple versions depending on year, vehicle and Euro regs.

Don't be worrying about the oil counter at this stage. Go back and check it after a month or so. It doesn't clock it up by mileage...

[michok2]

thanks, im gonna do that.
By the way, what do you think about this second thing, bumping revs during change? is that might be this adaptation thing? i've heard that it might take approx even up to 500 miles/km

[GiveMeABreak]

The gearbox will adapt as you drive the vehicle, so just drive it normally.

The oil counter uses 'units' that increment - whenever the transmission is subject to too high a load or too high an ambient temperature.
