"You can use atf3 or backwards compatible atf4."

It is not backwards compatible.
Not in MB-Gearboxes.

ATF III has a higher liquidness than ATF IID.
It will change your gearboxaction, strongly.
It can also cause brake bands slipp and can burn'em up.

The gearboxes are hydraulically operated without computer operation.
They need the 100% specific oil for the right action on the right time, with the right liquidness, comprehensive restistence, friction coefficent and that all at different defined temperatures.

Good drivers will be able to notice also differences between ATF IIDs with same standards but different producers.

But most drivers don't feel anything and have no idea how good and soft this old gearboxes can work.
