Why is this part missing on my car? Does everyone else still have theirs? What are the consequences of not having one on the car?

Big difference to me- you should buy one. Not uncommon for it to be damaged or missing.

I have "heard" it also acts to help cool the transmission.

Neither of my cars had it on when I bought it, but I plan to find one and get it on at some point in the future.

Shockingly my SDL and 300SEL both still had them after all these years.

I have not driven with the SDL one in forever (it is in my garage) so I cannot recall how much quieter it made the vehicle. The 300SEL/M103 is so quiet when I drive it I almost forget the vehicle is on. It seems to subdue the high RPM cruising noise.

It does effect drag...

It will probably change the airflow a bit under the engine- doubt it makes a difference to trans temp.. but it's possible. These parts are going up every year $$. For my 124.034, it runs about $130. There are some aftermarket panels available for some models...
