What is TCC? I put a 2002 5.3/4L60E into my 87 Chevy Truck. Was having issues with it bogging bad at acceleration. I hooked up the wire for TCC to constant hot and now everything works fine got all the power in the world, does great. So does this lock up the torque converter? Will it hurt for the torque converter to stay locked up all the time while doing daily driving? I belive this should hook to the break pedel so when you press the break pedal is unlocks the converter is this correct??
