    4L80E swap in Hummer H2 TCC problem

    4L80e Swap in Hummer H2 TCC problem.
    Hi, I did transmission swap in my H2. Everything working just fine, no trouble codes but when oil reaches 185 deg F the TCC stops working, everything normal up to that point and as I said before no trouble codes. Have you guys exspirienced similar problem..? What could be the problem..? Is there some setting in the map that I'm missing out..?
    Best regards,
    Boggi
