Transmission crush rings

In the Mercedes Transmission Svc. Kit, there were 3 crush rings.

The MB kit # was A 115 270 03 98

(2) measure .780" or 19.8 mm
(1) measures .519" or 13.18 mm

I knew there would be two crush rings, one for the pan drain and one for the torque converter, but what is the third one for?
Is it a spare?

Thanks.. Gary

Ok. Two large rings seal the banjo coming to the pan which is also the drain. The small must be the torque converter drain.
Sorry, answered my own question.

Yes.
