Hi everyone,

My beautiful Volvo XC60 is driving me crazy.

When going uphill and the revs drop to around 1500 rpm, the car start juddering and it only stop if I accelerate hard. I notice it happen only with 5th and 6th gear.

I changed/flushed the transmission fluid, also the car went to the dealer for a software update but still no luck, she keeps juddering.

Do you guys have any idea of what problem could it be?

Thanks for your help and sorry for my English.
Is this the notorious "powershi+" / Dual Clutch transmission or another type?
No lights or codes on the dash. The trasmission is the 6 speed Auto, Aisin TF-80SC
Volvo dealer would read the codes ask if we're any, should have told you if we're any though. Maybe other issue.
Where are you?
We can recommend cheaper, better indie volvo shop.
I asked them, no codes found. They couldn't even notice the problem, and I know why, because they drove on high rpm. The car only shakes when you have a hill after a flat road, it's like the car refuses to downshift. I have been thinking if it's a problem with the mounts..??

I am in Brisbane, please pass me some contacts if you know someone.
Thanks
@Dauntless that's sounds different, I don't think my car has a misfire problem, it's more an issue of selecting the right gear for the right revs and speed, if I drive it in Manual mode I have no problem at all.
Thanks @Ex850R ..they have great reviews, I'll contact them Monday.
@Musky85 what sort of KLMS are on the TF-80sc?

I helped a friend out to do a drain and fill on his XC90 D5 with the same tranny after he said it was flaring between shifts and now reports improvement.

Also noticed you did the fluid change yourself, did you use genuine or JWS3309 fluid? My understanding is that it's needed for the correct function of the lock up converter in applicable transmissions.

3309 or any high quality full syn (that lists compliance) is fine
Just have to reset adaptation every time you flush fluid
Is the adaptation necessary, particularly if only doing a drain and fill diluting old with new (shouldn't the tranny continue to adapt to the minor change in fluid dynamics)?

I thought adaptation was particularly necessary after a rebuild etc. I've been doing Mobil ATF3309 (the Volvo OEM supplier of genuine 3309 fluid if I'm correct) with no issues. I'm planning on continuing drain and fills every 20-30 K on my transmissions and it's impractical and too costly to get a dealer to reset adaptations for me unless I've got an actual problem.
I went to the bloody Autobarn and they sold me a Penrite full syn, I might change the fluid again and replace it with Mobil ATF3309, and also buy Vida to reset the adaption.

I have been reading on the web and some says that can be a problem with engine mounts as well.

Do you think guys might be possible?

Spend $120 and have your own dice unit like the rest of us?
Any flush of more than 2L should really get an adaption unless the fluid coming out is quite clean already

the penrite full syn is better than 3309

engine mounts are common
Better than 3309? 3309 is not a brand it's a specification. Penrite has in the past claimed specifications it's doesn't have (read ZF 6HP26 6 speed special auto oil, Penrite no longer has a recommendation... There's apparently some reason behind that). Penrite is my most trusted brand, but correct specification is more important than brand. Mobil ATF3309 is supposedly the OEM product for Volvo as best I could read up, as much as I use Penrite for pretty much everything I'm a bit dubious about their synthetic ATF's claiming every spec under the sun.

I emailed Penrite to double check if the fluid was ok for my car and they replied: "It is, based on the information we are given".

I bought the Mobil3309 and Vida, I'll let you know if get any improvment once I flush the oil again and reset the adaption.

It's a minimal level of performance in specific tests
The penrite fluid exceeds those requirements and is a better fluid

3309 is a medium quality mineral fluid its breaks down and starts failing to meet its minimum specifications far sooner than a good synthetic will

I've got penrite in my zf 6 speed in my BMW
100k km of absolute abuse and it's doing better than on the zf life fluid
