Mr Tidy said:Ross at RBM changed my gearbox and diff oil when I had an Inspection 2 in 2020 but I don't know what he used.
But I did get him to remove the CDV and don't have any issues with the change from first to second so if your car still has it I'd remove it!

I’ve tried various places for the fluid changes and even had the clutch bled a couple of times but for whatever reason, this change has been great.
The only other time it was this good was when I put Royal purple in along with brand new Vibratecnics engine mounts and rogue gearbox mounts. For that first week or two it was ‘perfect’ but sadly the positive effect didn’t last long so I went back to bmw fluids.
If your driveline mounts are softening I’d say this will have just as big an effect on the shift as the fluid, possibly more, so it might be worth considering replacements.
The redline mix you mention has had some positive reviews but I’ve not tried that yet.

I know this has always been an issue as when the M was first released people left right and centre were taking there cars back and complaining
At first BMW actually replaced a few under warranty.

I’m just outside Ringwood when I’m in the UK but drive a black MC. I think Martyn has a grey MC and is around the Poole area. Are you driving a Sepang roadster by any chance? I saw one last month at the Wilton wake up which looked very tidy.

I have ordered the Redline ATF D4 and The Mtl .
I will post here with my thoughts on this (better than OEM oil or not)

For the gearbox not for the diff though right? Diff has a 'diff'erent kind of oil.....![]()
