Sorry Ive been on the tahoeyukonforum. Turned out to be the Rear Main Seal. After changing the RMS im not seeing any visible oil leaks between the engine/trans or anywhere else. But I am having to add a quart or 2 between oil changes. My engine has 250,000+ miles

 

Thanks for the reply!! Mine has 374k on it. Just done everything you mentioned including rear main seal and still having the issue. Only thing I can think of is the mechanic didn’t actually do the seal like he said. 🤦🏻‍♀️
