Drive the car atleast 2000 miles and send an oil sample to Blackstone lab for an analysis.
Browse their instructions and educate yourself as to what services they offer and what they do. They can analyse the transmission as well as your engine oil and can tell you what elements and in what quantity they are present in the oil.
Click on the sample test in the attached link below to see what the tests would tell you.
They send you a free kit and usually charge around $25-$30/test.
Hope that helps.
