My OPC just confirmed it’s happening too. My car was registered 1/3/16 and is effected.
Shiny new box and diff before the track day season.
Did you call them or they called you?Shiny new box and diff before the track day season.

I checked mine and got this:

Replace manual transmission | WJ88 | Feb 08,2019
Description
A 6-speed manual gearbox, in which the durability of the gear wheel for 3rd gear cannot be guaranteed over the entire service life of the vehicle due to the high performance characteristic of the drive train, was installed on the affected vehicles.
Remedy
the transmission must be replaced by an optimised transmission with reinforced gear wheels.

Would good to get a check up on the oil separator part though.

Excuse my ignorance, but it was mentioned somewhere about the diff being part of this recall, surely they are two different parts and the original diff will stay in place when the new gearbox is fitted?
The diff is part of the gearbox in the gt4 afaik. new gearbox comes with a new diff. Anyway new diff plates for free, what's not to like about that?

June 2016 registered car. Waiting to hear back from OPC on plan to sort.
Would be good if you can report back on their estimate of how long they will need the car for. I guess mine will be subject to the recall but with some trips already planned for the very near future, those plans would be ruined if they wanted the car for 4 weeks or more!isaldiri said:

I believe it is a ‘feature/characteristic’… but you’ll be able to give us your feedback once you’ve had your box replaced.
I’m with TDT on this. When I first had the car I wondered about the noise and went through every ‘in cabin’ review on YouTube just to hear it! It’s part of the car and not a faulty part. ghiblicup said:

The following is my opinion based on 2yrs experience and research of the subjects being talked about on this thread.
The transmission in the GT4's is exactly the same as in any other manual 981 or for that matter 718.
Having had most of the interior out of my GT4 for one reason or another I have seen no evidence that any of the sound proofing is missing. I also cannot find any difference, sound proofing wise, between the Cayman S and GT4 parts manuals. The whine noise is present with the car in neutral and therefore comes from the engine, therefore, if it is true that Porsche issued a bulletin regarding replacing the Oil Separator with a later type, then this might just be the the whine problem The question remains - has anyone had experience of their Oil Separator being changed and the whine being eliminated?
Finally lets not forget this thread is about a transmission recall due to Getrag changing the syncro attachment on 3rd gear from a long proven interference fit spline, to a cheaper substandard weld at the beginning of 2016. Your replacement transmission will be exactly the same as your old transmission other than 3rd gear will revert back to the splined version. This will not make any difference to the whine noise.
