I have been doing some research and this is the exact problem I am having with my car. I have not taken my 2014 auto cruze LS to the dealer yet. I have 39xxx on the clock. Would something like this be covered under the 100k powertrain warranty?TCC is the transmission converter clutch. When we refer to a locking torque converter it is the TCC that is performing that function. An early apply of the TCC can lead to a stunble, sag or hesitation; as would popping the clutch in too high a gear standard transmission.
