Didn't we have this conversation a month or so ago? One problem is that your integrand blows up at the limits of 0 and pi, so you need to stop the integration a little larger than 0 and a little smaller than pi. Also, FindRoot has trouble with a constant inside of NIntegrate like that. Try making a separate function like I did in the attached workbook. It looks like the root of your problem is a T2 value of about 11,000 - see attached.
