no I am running a lq4 6.0 with a 4l80e and np205.. the engine and transmission came out of a 2006 2500hd 2wd and its in a 77 k3500 crewcab when i did the swap I never hooked up the tcc wire I thought it was just for the cruise.i have always had to let off the gas pedal just a little for the transmission to go into overdrive and it seems to just glide into overdrive not just shift rite into it. I have been driving it for about 4 years without the tcc switch hooked up I drove it for a short distance today and it seemed then be the same but I will try it out and drive it a little more and see how it does .thanks for the info on the tcc I never knew there was a clutch in the torque converter.
