Hi, just a question for clarification.
So the new gearboxes are after 2012 or also include 2012 models?
Amazing article thank you!

Hi Zack, I have a Grande Punto 1.3mjet, and mine whines too in 3rd and 4th, even after oil change. Other gears are just fine. Has yours failed yet?

Hi, is possible to use the Fuchs gearbox oil in the Astra K 1.6 Turbo SIDI (2017) with the M32 gearbox?

I am about to change the oil on my M32 Gen 2 (Astra K). After reading a number of articles and opinions I have opted for 3L of the Fuchs Sintofluid FE 75W which is purely a GL4 oil. Wasn’t sure about the Fuchs Sintofluid 75W 80 as it’s GL4 / GL5 spec which presumably could be less then ideal for the Synchromesh?

In reply to Tony. Can Vauxhall call a failed bearing 'wear and tear'? My gearbox had a catastrophic failure due to a failed bearing, which means the whole gearbox needs replacing. They refused to fix it on Lifetime warranty due to wear and tear. It has done 74,000 miles. many thanks

Hi
The 2012-2017 Holden Barina RS 1.4L turbo (TM platform for Australian and New Zealand) has the M32 gearbox. It uses the gen two gearbox with the larger bearings.
I’ve been using Penrite 75w/80 Transgear GL4 (2.4 litres) in two of these vehicles and they are running very well with no issues. I previously had Redline MT-LV 70W/75W however this proved to be slightly notchy when going from 1st to 2nd and had some backlash when the oil was warm.

And on a slightly different note which may not be useful for this forum so please feel free to ignore the rest.
These little 1.4 turbo engines also have a huge issue with the stock turbo chargers which generally fail with less than 50,000kms on the clock due to waste gate issues and cracks in the cast iron housings (neither are oil related, just bad design).

Hi,

Fantastic read, thank you for taking the time to write all this.
I have a 2006 Signum, 2.2 direct injection. (petrol). I have the ‘whirring’ sound – sounds like a jump jet getting ready for take off – but it’s only on 3rd and 4th, which is confusing the hell out of me… Any ideas?

Cheers again,

Zack
