In the middle of changing filter and fluid on an 86 560sl. First thing I noticed is the burned smeel of the fluid-color looks ok. Time for a change.

Question is: I see a drain plug on the transmission housing underneath where the torque converter would be. Is this the drain plug for same? I thought I would have to rotate the crank to get at the drain plug but it is right there looking at me on the housing.
Thanks.
