Update incase anyone else comes up against this.
I've cracked it by using a iDatalink Maestro SW, did have to ship from the US, but from amazon.com it's still quite reasonable.

Pretty straightforward to wire up. I used the Connects2 harness and just cut the plug off that would be for their SWC interface.
Anyway, works like a charm and is even re-programmable, should you want volume up to map to volume down 😂

 

Not your seat is it? My seat creaks a fair amount sometimes, and, like you say, it's exactly that kind of "bed spring" noise, and doesn't sound like it's coming from outside the car.
Another prime suspect would be the infamous clutch squeak, but it doesn't seem like you're changing gear in the video.
Does it happen every time you pull away? It seems to be when you're already on the move, is it at the same speed everytime?

Suspension bushings adjusting? Might be worth giving the bushes a liberal spray with a lubricant and then see if it continues. This isn't a full fix but more of a diagnostic technique to help identify the cause.

What time stamp should we hear the noise?

How old is the car and are there any mods?

Try checking the exhaust or heat shields for rubbing.

Are the diff bushings done up tight?

Are the brake pads sticking at all?

Is the squeak from the seat belt socket?


I can’t really tell what the noise is so I’m just throwing some ideas out lol

Hello All.
Been lurking and reading through a lot of info on this wonderful car the last few weeks and after a lot of fiddling/fixing and service/MOT I finally have a shiny red sports car! Always adored sports cars and wanted one since I started driving (family needs put that out the window till now) and today I got mine at last!  Only took 42 years!  Absolutely adore the car, its beatiful and fun and everything I could have wanted in a car. And not as slow as some people make it out to be!
Unfortunately by the time I got all the neccesary bits done (kids to bed, food, insurance etc.) its gotten too dark to get a good photo! So, that will come soon hopefully, need to make it a good one or it'll ruin the suspense of it lol.
 
Thank you all of you who've posted and discussed and everything in between for all the information and learning that you've provided over the last couple of weeks of waiting on it.  Look forward to mingling a bit!

I don't own a gt86 anymore, but I can confirm my 2017 aero did exactly what you are describing from 2nd to 3rd. As others have said, I think it's more of a characteristic, so I honestly wouldn't worry about it 😀

I'd get the gearbox oil changed to something decent. Abbey put Millers gear oil in mine and that really improved the shifting feel. Shouldn't be too expensive, and can only help. 
Ask them to install MTEC shift springs too. They really make a difference to shift quality, they center the gearstick with more force which makes shifts across the centre of the gate easier and more precise. Perhaps what you're feeling is the stick catching on the gate slightly as you shift into third...before the shift springs if I shifted too quickly from 2nd to 3rd it was sometimes possible to stick on the gate between 1st and 3rd...the stronger MTEC springs help with that by applying a stronger centring force to the stick. 

I have the shifter springs and they definitely help shift quality.

An aftermarket shift spring and gearbox bushing might help.  They noticeably improve the shift quality - more than you would think is possible - and don't cost a fortune.  Your profile says you're in Croydon, so maybe have a word with @Mark@Abbey M/S, they're right on your doorstep and know the GT86 very well.  The bushing apparently increases noise, but I had other stuff fitted at the same time so couldn't tell you how bad it is.
(ETA - they don't particularly change the slight obstructiveness when cold though)

Not OEM currently. Motul now. I also went down the oil change route , when that did not work , I changed the clutch line with a goodridge Braided line reading a forum post and hoping that would help. All placebo effect waned off after a few days and nothing changed. This was 4 years ago and my gearbox is still fine So I've given up and see it is as a characteristic.

Most common notchiness twins owners with MT gearbox observe - is harder to get into 2nd when cold. Most ignore, as it goes away after 5min of driving.
Now if it's hard to get 2>3 .. imho it's something else. Unfortunately i don't know well, what it might be and how to fix. One thing i'd try, is to adjust plate that positions lever at right places .. was it reverse lockout plate? If that doesn't help .. while oil change is relatively simplest/cheapest thing to do, so worth trying for that reason, but i somewhat doubt if it will fix (after all, other gear engagement is fine?), i suspect something wrong with gearbox of this specific car. But as it's 2018 .. there should be warranty, no? Make dealership fix/replace it. Disassembly of gearbox to inspect synchros/gears and-or replace will take long time and will cost a lot. New gearbox costs extraorbitant sums (IIRC ~4K?). If warranty is not an option, i'd also explore to get used gearbox (600-1K), as imho it would be cheaper and quicker then disassembly/overhaul/cost of parts/time to receive them

I don't have the newer model, but being an owner for a while can tell you that the gearbox is generally bullet proof with no reliability issues. It can how ever be a bit temperamental with the notchiness in those places you mention, two to three or three to two... I have tried everything and got no result except placebo. So my honest advise will be to get used to it and see that as a characteristic feature not as a limitation that needs to be addressed.

Hi Folks,
I've finally taken the plunge and bought a 2018 GT86.
Loving it so far, so much fun to drive. I've come from owning a Mitsubishi GTO which never failed to have a steady stream of stuff going wrong all the time, so hoping this will prove a bit more dependable
I do see what you all mean about the notchy gearbox, second is pretty bad from cold but seems alright after 20 mins or so,  and 2 -> 3 you can definitely feel it catching even when its warm.
Otherwise I'm supremely happy

Enjoy the car. Its extremely reliable with all niggles fixed in your iteration. Just possibly a low Ah battery which might need replacement, unless done in warranty. Worth checking if it's 45Ah , if yes, then sooner or later time will come unless its a daily.
