I have owned for two weeks already a W111 220S sedan, which I I am in love with.
I am trying to get the basic maintenance done, sinde I have no idea of the previous service history (of course not!! its a 64'!!!)

I already changed spark plugs filters, etc, and now I wanted to change all fluids.

I have no idea what goes inside the manual 4speed gearbox. I`ve found conflicting information on the web, stating ATF as well as some other stuff.

Can anyone help me with this? Is ATF correct for the manual gearbox?

TIA
