The new replacement Auto Transmission Mount 1242400618 has a bolt on top that goes inside the hole below the output flange/yoke. On my mercedes e320 wagon, due to various issues involving driveline, flexidiscs replacement, etc., this hole is missing. My question is the Transmission case rear part number 124 270 01 11 has this hole that the tranmission mount bolt goes in or is it part of the transmission housing? See picture that I circled (red) that is missing due to damage. Anyone out there can confirm this is part of the transmission case rear? Thanks to all for reading.
