As for the leak being from synthetic oil, tell them they are full of BS. Oil is oil, Mobil 1 meets AND EXCEEDS the GM requirement, and there should be NO leaks. Not that hard to remove T/case and trans on the H3, and then remove the flywheel and install a new rear seal. Probably not installed correctly in the plant. Not a big problem, but like axle seals, some will leak until repaired.

Thanks for the information. I will take it in tomorrow to the dealership and see their actions.

I developed a leak from my engine rear main seal at 2400 miles. I agree with f5fstop "Not that hard to remove T/case and trans on the H3, and then remove the flywheel and install a new rear seal." My brother is a GM mechanic and did the job for me. Everything was covered under the warranty. I have been running with Mobile 1 ever since with no more leaks.
