It is easier to get the correct help if you tell us where you are...
MB 236.12 or 236.10 will also work, but the latest types are recommended.
Getting the level right is important, and exacting.
The level is measured with the car on level ground with the engine running and the transmission in neutral. You break off the locking tab to remove the dipstick tube cap, then fit a new one.
Ideally the transmission should be at operating temperature - 80 deg. C. This is only achieved after driving fast for 10 to 20 miles.
The fluid level varies considerably according to oil temp (about 0.8mm per deg. C), and there's a second mark on the dipstick for ambient temp level measurement (20 deg. C).
The dipstick tool is long, and has to wind round lots of bends to reach the tranny sump. When it hits the bottom, it will still have several inches sticking out the top.
Keep the dipstick spotlessly clean at all times.
