How do I add transmission oil to my gearbox?

[Philip1972]

Car is a 2011 E350 CDI auto (7G).

And I know it should be a pro job only, but just humour me!

Is there a tube under the bonnet somewhere?

No, it has to be pumped up into the gearbox sump from below.

Here are the WIS procs for draining and refilling a 722.9 (7G) gearbox.

Oh bollocks.

Thank you!
