How many miles on the car? I did a Transgo valve body kit and rebuilt the linear solenoids and that made the car shift like new. I also had a really harsh shift from park to drive that cleaned up as well. Its not as big of a job as it sounds and well worth the time and $ 125.00 for the Transgo kit.

the car has 17000km on it, think that's about 10500 miles.
Transgo kit looks nice but I would rater have new solenoids if I would go that deep in to the transmission.

The fun ended today, now the delayed shifts from 3 to 4 gear are back.

What should be the next step, is it the 3 solenoids ?
Its so frustrating that it shifts great in all other circumstances. (if I'm really picky standing still and shifting from P to D or R might be smoother)

Might be something other than software electronics. I had to rebuild my linear solenoids to get rid of that shift flare.

Did you have a flare between 3 to 4 also?
Since it's not really easy I would like to hear from someone that it actually might help.
I'm thinking of doing it this way with a similar tool.
The upside of doing a rebuild of the solenoids is that there should not be any calibrating issues.
So this tool together with new bushings and a gasket for the pan should do the trick.

I did it with a Transgo kit that included all the parts required to service the valve body and linear solenoids. There are a few good videos on this site on how to lower the subframe and gain access to the valve body. I was pretty intimidated by the job description at first but it is actually a relatively easy job. I did it over 2 days but could probably do it in 6 hours after having done it once. I believe the video I followed was by oragex.
The kit was about $150.00 and fixed all my shifting issues. My transmission would really slam going from park to drive or reverse also, now it is very smooth and no more shift flare between 3-4. This was done after changing the B servo which didn't seem to help anything.

Just to add, You don't even have to take the valve body off if you don't want to. Many people just take the solenoids off and rebuild them. I chose to remove the valve body and clean it thoroughly, the Transgo kit includes some VB upgrades that I thought I might as well do, being that I was that far into the job already.
And yes, I had the 3-4 shift flare plus a few other shifting issues, most notably the slamming between park and drive/ reverse.

Thanks for the feedback and information.
What seems to be the hardest part of this service is to get the pan off and on.

Do you have to drain the oil completely or can I just tak the pan off and let the oil that's in there drain that way ?

I can’t recall what I did, although you’ll want to measure how much oil comes out to put the same amount back in. A few posters make a big deal out of getting the pan bolts off but I found no problems with mine and I live in Canada where they salt the roads pretty heavily. Just take your torx bit 3/8 Drive and tap it with a light hammer into the bolts before you turn the bolt and go slowly, it shouldn’t be a problem.

OK so now I'm half in to this job, getting to the solenoids take a bit of time and patience. :)
I have taken the solenoids apart and cleaned them and change to new bushings. The old ones where not that bad but new is new.

Question: The blue one did rattle when I did the shake test before taking it apart.
To me that would indicate that the shuttle inside was locked up inside ?

Now when they are all serviced they rattle fine before I put the spring and shuttle together. When when everything is put together they are all silent.

Any one hade a solenoid locked up like this blue one? and could that cause a shift flare 3 to 4 only ?
