If you change it via sump sump you won’t require adaptation reset.

I have Vida so I did do it after 4 changes but I drove it between each change without incidence.

Adaption reset isn't software updates.

Software updates can only be done by a dealer.

Interesting point, it’s possible on a 2017 if it has not been to a main dealer for a while isn’t it! Bit quick on the skin reading my side as mine is a 2012 and as such there are obviously no updates for me (mine was serviced at Volvo last 2018)

Newer cars do have a tendency to require software updates.

Eitherway, you can't do software updates from a DIY VIDA laptop at home, only the main dealer can do it. That's one of the bonuses of getting the dealer to service your car. With your particular vehicle being older, chances are, its probably got its latest software. Although, if it didn't, only the main dealer could update it.

An adaptions reset can be done from a DIY VIDA laptop though, but that's not to be confused with a software update.

Adaptions & software updates are totally different.

So here is the story,
I bought second hand company owned 2017 Volvo V90 D4 Inscription few months ago with 113k miles (I know what you thinking, I must be mad buying such high milage car ) anyway it had full Volvo dealership service history with belt done at 87k (which is unusual.. people usually ditching cars around 90k mikes so they wouldn't need to pay £1k to change it) car had almost full spec and I couldn't resist it.
So back to Transmission, since I bought it I have done around 7k miles and car now has over 120k miles on the clock. I noticed some harder shifting especially when slowing down from high speeds when approaching some junction or roundabouts..
I spoke to dealership where car have been serviced and there is no record of TF being changed.
I dont believe this Volvo "sealed for life" nonsense because its probably covered for 3years/60k miles while car has warranty. After all its mechanical part with lots of movement involved.
And here is the million £$ question should I change it or should I not (and just sell the car ?)
Because half of the people say change it, other half says leave it because it might make it worse.

Thanks
Karl

It's an old wives tale spread on the internet like so many other lies these days going around forums and spreading like wild fire ...
Volvo have NEVER said their transmissions are sealed for life , They have had a service schedule for them for the last 50 years .. It is optional however ... otherwise it would double the cost of the service ... It's up to you and the service department to work out what is best for you ..

Yes of course changing the oil would be beneficial .. again internet old wives tales that it causes problems .. they ALWAYS benefit from an oil change and also just as importantly a software update as no doubt that has been neglected ,,, Give it a go

I, personally, have phoned up a Volvo Main Dealer Service Dept to discuss the service history of a car I had bought, and specifically whether they had ever performed an ATF change. I, personally, have been told that it isn't a service they offer because it is a 'sealed for life' gearbox.

I, patiently, explained that it wasn't the case, and that it was an option. They promised to investigate and return. They never did**.

It is out there. I do not claim that my sample of one is in any way representative, but I am also very clear I am not an old wife, least not when I last looked.

**They did send me the service history whilst in their hands though, which was helpful.

Clan, could you just confirm whether an ATF change is on the Volvo Service Schedule in other than what are described as 'arduous' operating conditions?

well that is a serious failing of a member of their staff , I would report it to kill off these rumours .. The dealer has been done out of about £300 by this person and done you no favours either ..
The service reception staff seem to change on every visit you never see the same person twice .. Its a thankless job to be honest unless you have a serious passion . They don't know how much is involved and how much knowledge they need to know .....

conditions they describe are taxi work or towing or even constant short journeys where the gears are continually changing .. the gearboxes will easily do 100,000+++ miles with no attention , but its the second owner who needs to sort the maintenance .. you could take the small plug out of the centre of the drain plug and see what colour the fluid is that trickles out ..

Thanks for advice

I'd just change it every 35 to 40,000 miles from now on. It won't last forever but if you change it again at say between 150 and 160,000 it will be 200,000 by the time a second one is due. At which time you may not even still own the car or it may be well on the way to be recycled. One large repair cost at that age would probably not be viable, although there's always the breaker-component option.

Hi,

I did reset adaptation after TM oil change with my "Autel MaxiCOM MK808" because TM oil newer been changed before and also because I bought it with high milage so TM could reset and adapt to my driving style. I hope that helps

Oh as I see this reply is a bit late
