My 2002 CLK55AMG has 38,000 mi on it so figured it was due for a trans fluid change. I drained the pan and the fluid looked a little dark so I pulled the rubber dust cover caps and turned the eng crank pulley with a 1 1/16 socket rotated the eng twice and I can not find a drain plug on the torque converter? It has a 722.6 trans like my 96 SL500 but the plug is missing ,Did they do away with it in 2002?
