- remove/ignore 3-2 control signal.

The reason you may want to drive a 4L80E from a 4L60E segment is that the car segment keeps the TCC locked on zero throttle, this gives a manual trans feel.
On the 2-3 solenoid signal... what signal do i invert? the PCM output signal from this wire? 2-3 solenoid?? what signal does it outputs? ground? or positive voltagE?

about the TCC i cant understand it 100%, maybe with a simple diagram

thanks a lot
