You won't know if you have a TC drain until you look for it, which require getting under the car and watching through the access port as you rotate the crank. It is very small - like the size of a pencil eraser - so it can be easy to miss. My understanding is that the earliest 722.9's did not have the drain.

As I'm getting ready to do the ATF + filter change on my 2005 CLK500 with 7 speed trany 722.901, I came across one of the posts where High-End Fluke infrared Thermometer's readings measuring temperature at the pan were compared with MB STAR, and it says that it was OFF by a much as 10°C! And it warns not to use the IR Thermometer. I don't have the MB star, and was planning to use the infrared thermometer. Now I'm concerned that it will affect the level significantly. Has anyone compared the readings of MB Star and IR Thermometer? Thank you.

My Ryyobi IR thermometer matched SDS directly.

I appreciate your quick response. This is what I was hopping to hear. I'll probably get the IR thermometers from amazon. It looks like Etekcity Lasergrip 774 or Etekcity Lasergrip 800 have good ratings.
