430 Weird neutral problem HELP needed!

I will certainly have another mecanic look into it. I will have him take it out, look at and bleed it again with the complete system.
I will also have him change the accumulator that is an original from 2006 at the same time to start...as I was suggested by some great member her. Knowing that he did this now and seing the response here, I am questionning myself on what really happenned here.
I am keeping you tread and will show him when I go in July.
One thing funny, this other place is telling that he has another F430 that he his working on that as a really similar issue were is stops and cvant shift anything anymore...A little like mine. So until July, he will be testing some stuff on his car so, it might be a good thing for me
I will ry to reproduce this problem and post the video here in the next week.
Maybe it could help. I also told this new place I woud do so to compare with his other problematic F430.
I guess they are getting old
I wish it would just stay on Neutral and never go back to normal, it would be an easier fix.
Thanks !

 

Thanks...I will have time o test this in the next weeks so I will do so for certain.
But th eweird thisng is also that, after 15 minutes, I can ride it all the rest of the day with no issue. So, the coil could only do this once and after be ok for the rest of the day after being coll down 15 minutes? This is the most weird part of my problem. It does this once a day, about after 30 minutes of driving.
But I will test this for certain before my july appointment.

 

If I remember well, because it is 18 months ago, Sherkan, the GTE engenering owner, told me they adjusted it at the regular specs but it has to be fitted to my car.
But I am not an expert so I had to idea what he was saying. I will pull up my document on this tomorrow and see what is on the invoice. It should state it.
But it was not well aligned as my mechanic re-installed without this alignment tool and it did not work properly. He then spoke with GTE and they told him about this tool. He was not aware it was needed to re-install it.

 

Thanks for confirming this...As again, this guy told me that if it would be a selenoid, there would be a code so...it is mechanical and I need to change the complete system. Man...this is unbelievable. The worts is I dont mind spending the few hundreds $ to change all of them to test but he said it was not worth and my system must be contaminated du to the fact that I only had the actuator rebuild instead of changing everything the first time.
I cant wait in July to get a second opnion with the actuator out of the car!

 

Anybody has those other option part number (solenoid, valves)so I can start buying those if the prices are reasonable...
And, anyone is running with the Alfa Romeo Accumulator and all is fine? It is a third of the price of the Ferrari one and from what I am reading here , it is the same. Part 71751195

Everyone who responded so far to help me...YOU GUYS ARE GREAT ! I am Learning so much in the last week that my hopes are getting higher...And I wont have to sell a lung or a body part to have it repaired !!! hahahahaha!

 

Ok. But My actuator as been rebuild less than 500km ago and talking to many people, they all told me they never had any problem with a rebuild one... I did not see any negative comment on GTE as well. . The problem appears only once during a day run. Does yours resets itself after this 15 minute wait and never do it again?
Because if getting hot is doing this, if would do it again after another 30 minutes drive, because it would heat up again. What I find bizarre is that I can run the car for the rest of the day, and it will never reply this issue the same day, even if the car cools down.
I am curious to see if you are also able to run with the car after waiting for 15 minutes, and this...for the rest of the day even if the car is stopped and cooled down after.
At worst, I'll find a used actuator but it may not be what is causing this.
I also noticed that it is shifting down from 4 to 3rd gear that it is doing it...or 3rd going to 2nd..
Never done it at other speed so far. Does it in automatic mode as well.
