I am about to service my gearbox and have purchased all parts and tools. There are many discussions on which oil to use but I had had no issues in the past with this oil. There are many write ups out there so I didn't bother to repeat. I just thought I would pass on my findings incase any member is considering doing their own service.
I will be doing this twice or more in my ownership, so invested to save and want it done correctly. The last time it was serviced by MB they only used 5 litres of fluid so they did not drain the TC.
I want to drain as much as I can so I will be flushing through 9 plus 1 litre each service.
It will bring my service cost down to £100.48 per service. I already own an infrared thermometer but they are £13.99 from amazon if not. https://www.amazon.co.uk/dp/B01G6E61JW/ref=pe_385721_37986871_TE_item
