AC Condensate Drain location on 2023 Yukon

[tgsz]

I've read through the threads in this forum and the sIerra forum, but where the schematic says the drain should be is a flat spot on the firewall on my car.  

I notice that the condensate drips down on the transmission (driver side actually) and then down on the balancing tube on the exhaust mid-section where you hear it sizzling.   I'm guessing this means the drain is actually above the transmission housing.

 

I pulled the center console sides off and lifted the carpets up on both sides... no luck finding where the condensate drain would pass through on the transmission tunnel. 

 

If someone has a photo or screenshot from the service manual for the 2023 yukon showing where it is under the car - that would be great.  I can find the rear one easily under the rear passenger quarter.
