If you may or may not already know, my S40 suffered transmission failure. You can read more about it here.

On my service writeup, the following part was replaced:
8667378-7 CONTROL CYLINDE

I'm wondering if this is the master/slave cylinder.

Yep, that's the slave cylinder, located within the transmission/clutch housing. And if this isn't a warranty job, it should be because that is not a wear item. And it can cause the clutch to slip, stick, etc leading to failure.

The throwout bearing and slave cyclinder are one piece, as confirmed by both mcvolvo in my original post and the dealership I just called who told me that this needs to be replaced during any clutch job. I'm still running around in circles.
