Adjusting ATF Levels Correctly

[VenomX]

Hi guys. W203 C240 here ( 722.6 transmissions )
Just replaced the " Pilot bushing " which plugs into the bottom of the car as it was leaking ( hopefully it was that )

Anyway. I just need some tips on getting the ATF levels correct, I bought an OE equivalent dipstick off Amazon and seems to be good quality and able to get hot/cold readings on it.

Other than having the car as level as I can get it, any other tips ?
Plan is to leave the car overnight, and check the cold level, check the hot level, and then adjust the hot level accordingly.

FYI I do have genuine Mercedes ATF which was surprisingly cheap but only a litre because I just need to top up whatever I lost during the leak which wasn't a great amount as I just checked the levels cold and they are too high
I also have a pela vacuum pump which is great for sucking up liquids through the filler caps. I used it for my engine oil change.

Thanks

Well obviously your level will rise when it's hot , so suck a bit out until it's within the cold section. Then take it from there .

The cold level mark is at 20 Deg c. If it's really cold it will read "low".

The hot temp is 80 degrees c and the gearbox will take an age to get to this temperature, at least 30 minutes of driving, so if using that, definitely make sure it's actually hot.

So, best to do on a 20deg C day without any driving?

Yes I would. Also, engine running
