ATF Dipstick level. C180 1994 Gearbox 722 421

[Dec]

Could anyone estimate how much ATF fluid I will need to top up, from the current level at the red mark, to the correct level at the yellow mark in the attached picture. Level taken with engine hot, running and in neutral.
The current level is very low, I must check for leaks under the car, I should have checked the level more often.

Thanks

Probably 1 to 2 litres. In reality it's probably better to buy 5 litres and perform an ATF change as it needs doing every 36k miles anyway.

Thanks Dieselman for the info and advice, I was afraid of overfiling.
