It’s likely the cause, this problem persisted until Aisin Warner used modified seals in the factory. Apparently from around Sept 2015 gearboxes were manufactured using the newly designed seals, which fixes the problem for good.

Fair enough.
I'm guessing there should then be a further technical journal which covers the models affected right up until the factory mod was standard?

yes there was one from about 2013 modified a couple of times as the next 2 years went by .

Obviously you need Vida for this (and some quiet roads!).

I have C30 D3 2012., 150000km (bought on 139000, not sure if gearbox oil was ever changed) with the same gearbox.
I've had problem of knock when going P/N -> D and a bit harsh downshift from fifth to 4th gear. Only when car/gearbox was warm!
First, last year oil was flushed but didn't fix the problem and now, 1 month ago valve body was changed. Everything was good for around ~2 weeks but same problem is happening. The guy who changed valve body told me to go to volvo dealer for software update and then contact him if problem persist (which I think it will..). Which of these suggestions in the quote should I try first.. or is there something else I should try?
The modified steel seal rings, behind the torque converter and first clutch.. are there codes for these parts?

Thank you!

This is the problem when your car is playing up and you dont take it to the experts who have the knowledge, you have spend a LOT of money on a valve body and labour .

This problem was around from about 2011 to 2013 then volvo brought out the fix, any dealer would have known about it, they had already spend a year trying a complex road test adaption process on many cars which could help..It all depends on the severity of the internal oil leakage There was later software to raise the oil pressure which often cured it .

You need to speak to your dealer and he will suggest the gearbox comes out and the modified Main shaft seal rings are fitted. then a software update.

I forgot to write that the first thing I did was that I went to the dealer and they right away suggested to change the valve body (which was one of the reasons why I went also with that option). Maybe I should suggest to them all these things that you were writing as I am not sure are they aware of it..

I went to the other dealer. They did TCM sw upgrade as suggested by the mechanic who changed the valve body. I talked with dealer and mentioned why am I doing the upgrade and when I explained the problem, they said that their solution is to change the whole transmission... so basically noone in Croatia knows what to do when this problem occurs.
Now after TCM upgrade, car feels good but I didn't have longer drives and suspect that problem will reoccur. If that happens, I will go to the volvo mechanic with your suggestion. I just didn't completely understand the parts:
- the modified steel seal rings.. are all the new rings modified, or I need to search for specific ones?
- behind the torque converter ... do I need new torque converter or something behind it? Modified or normal torque converter?
- first clutch ... modified or normal?
- After parts are fitted, tcm need update again?

Sorry for bothering but I didn't find anything by googling. Maybe you can just point me where to find solutions.

I didnt realise you were in Croatia, I suggest you talk to volvo direct and explain that their dealers around you are not helping you sort out the problem correctly., these garages don't seem to understand the problem . they seem to want to do everything except fix the problem ( New gearbox, valve body etc )
I cant suggest any more than I have already said apart from taking a trip to UK !
