hi friends this evening while I was driving my qp 2005 and slowed down to turn left or right the gearbox entered neutral, then without turning off the engine I press gear D from the gear lever and the car starts running again, someone has had this experience?

Mine did this too, wasn't sure if it was clutch or position sensor, so replaced both and its better

Steady on there armchair gurus ( include myself in same category). Replacing clutch is £2500 +
My car did this but was not a clutch. IN my case it dropped out of gear at other speeds too.
DIY Diagnostics only read the main engine ECU and suspect this needs the gearbox ECU codes. Check here for advice on F1 pump - plenty advice on checking if it is "on the way out"

Get to (specialist) workshop for diagnosis. Better spending two hours labour charge than buying any component.

Unexpected neutral but going into gear when asked again is a symptom of worn clutch acc. the indie who serviced mine.

As a new owner and car bought with unknown clutch wear (last owner had it serviced by an ex-Maserati tech but without suitable interrogation tool) I had to judge whether the 78% worn value meant I needed to get them done this time or next.
Mine does not do the unexpected neutral yet, I won't be doing lot of miles and most of those will be long distance with not much changing so I decided to wait.

Do you have a clutch wear reading from the last service?

as a long(er) term owner I bought QP with unknown clutch wear. When the F1 pump was replaced they measured clutch as eighty something percent worn. Still driving the car as my daily, but have choice of others so no sweat when it does pop.
Up to you how much good clutch to throw away. The majority of owners seem to prefer security of changing it before it breaks. Any other car you only fix on failure. You pay your money and take your choice.
Instead of replacing the clutch during F1 service I have invested the 2.5k in subframe repair and tyres. nothing wasted in Trident ownership.

Thanks rs.
Also take the point on other causes (than the clutch) to @Giual 's issue. Any news G, I see you haven't visited for a week?

Very good friend Gav told me years ago, don't ponder what anyone tells you but think why?

Of course any good technician will give their considered expert advice and I happily pay for their services. They might also have business to run. A decent business (like our owner) would never do this of course. Main dealers? In a heartbeat imho. I will be having my clutch replaced by garage where a working relationship already exists. Feel for you having to leap this hurdle early in ownership.

That answer was given because I asked what symptoms I should look out for, as an aid to making the stick or twist decision on clutch blackjack :)
The indie is Migliore. I've used many garage services for different cars over the years and my judgement is that they are superb - technically competent, flexible in approach and easy to talk to.

hi friends sorry for my absence !!!unfortunately I do not have many news for the defect of the gearbox in neutral because I used the car little and the problem did not occur and for a few days I had to park the car in the garage as I had problems with the engine cooling due to breakage water pipe tested, as soon as I can solve the problem with the cooling I will test the defect again. Thanks
