Maybe I should not have said that.��
keep in mind that when this fails, the evidence is normally found at/in the TCU (as the fluid wicks though the harness up to the TCU in the passenger footwell) rather than on the garage floor. I have had them fail on 3 of my 4 AMGs, now I just replace it whenever I change the transfilter as a precaution. As an added precaution on my SL55, I rotated the TCU so that the connector is at the bottom (so fluid wont fill it up in the event of a "pilot bushing" failure).

P.s. best to change this when it is cool as it is possible to spin the captive nut in its plastic "capture" if you do it warm-hot (and are unlucky) ... that is a tip passed on to me by a Mercedes Tech.
