My 2007 Vortec Max does the same thing it starts out slow and then all of a sudden the motor wakes up

Hi guys. I'm sorry if this turns up twice but I must have screwed something up the first time. Does anyone know if GM did away with the electronic torque converter lock? The reason I ask is I can hold the throttle at a steady speed and lightly step on the brake and there is no slight increase in RPM with my 2008 Z-71 5.3. All my other ones did have this. Thanks in advance!
