I think I half way figured it out... It sat for 4 days this week and I just jumped in it and threw it in drive, drove 50 feet, and put in neutral still running. Then it started the noise... I think the oil didn’t have time to get in the clutches good. I went back about 4 hours later, let it warm to one bar on the dash, drove the same amount, and no noise. So it looks like I just need to let it warm up a little better...
