    4L80E swap in Hummer H2

    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

    That is an excellent question that stands a better chance of being answered only if you follow the directions and post your tune file, and log file showing it doing the thing you say it does!
