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

There are loads of you tube vids on checking ATF levels. Level ground and cycle through the gears at 80 degrees temp, only use lint free cloth for wiping the stick.

As said in post #2.
You check the level with the engine running and the transmission in PARK.

Thanks for the useful info. Car is running nicely, does not seem to be leaking now !

Difficulty is getting the transmission to precisely 80c which I assume is near on impossible as it always fluctuates.
I have however checked consistently after many drives and many cold mornings etc and think the levels are about right now.

I do have an infrared thermometer which I will attempt to use this weekend after a 30 min drive, then when it's about 80c I will check again

Silly mistake I made was checking with the engine off, and I was like how on earth are the levels so high, then realised the engine needs to be running, then I started getting accurate readings.
