I'd suggest multiple drain and refill procedures (rather than a tranny flush) before you take more dramatic measures. You'll find useful DIY videos on YouTube. I noticed an improvement in drivability even on our low mileage '16 XC70. Not sure if it's appropriate for your model year but the Level 2.0 software update on our car was transformational. Good luck.

 

That's what I was thinking (can't do it DIY - don't have access to a garage with the vehicle lift), but I'm afraid whether at this stage it might do more harm than good, as the car stops going completely... Came here for community advice regarding that, how likely it is...

 

You don't need a lift to change the transmission fluid. Ramps will work just fine. Or driving onto some lumber. I've even driven onto a low curb once in a pinch (had to get under my car at a hotel this one time).

Drain and fill x3 (after driving a bit between each cycle and going through every gear) very likely will not make things any worse the than your current situation. A "power flush" could make things worse so avoid that. Start with the simple things first before jumping straight to replacing the transmission. I'm sure others could comment on transmission replacement, but don't assume you'll need one yet.

What this person said. 3x drain and fill as your would on a Honda/Acura. And never have a "flush" done by one of those machines. If you are not mechanically inclined, talk to your mechanic so they know what you want to have done. Should not be something they question as it is a fairly common procedure especially if they service Honda/Acura vehicles on a regular basis.

 

Yeah try the drain and fill. It’s really straightforward to do on these cars. You don’t need a lift at all to do it. Just need a level surface so you can properly set the fluid level.

If you have a slanted driveway (like I do) you can just ramps to make the car level.

You’ll want to reset the transmission overheat counter though. If you don’t have VIDA then a trip to the dealership will be needed (where they can also do the other service update if you haven’t done it).

I’d def do those two things before going for a replacement. You won’t do any more damage to it and it could solve your problem.

 

Not that I would jump to replacing the transmission, nor do I have any experience with this company, but it appears you can buy a reman. transmission here...

Not to worry! These are common P3 transmission quirks.

From what I've heard ...

1.) Drain-and-refill cycles

2.) Software update

3.) New valve body

Never have I heard (at least on Swedespeed) of an entire Aisin transmission needing replacement.

 

There are various TJs for shifting issues, depending on the specific concern. There may be something the dealer can do with VIDA or a software update and adaption might help. That's where I would start.
