The information on the 4L80 instruction pages don't seem to match with the instructions on the web page any more
I can't find the 'spare ports/clutch output settings anymore...The 4L80E does not use a lock-up feel solenoid, it PWMs the TCC solenoid directly. If you wish to pulse width modulate your torque converter's clutch, you will need to select 'Use PT3/Amp32 for LUF and SPR2/PA0/VB2 for TCC' under 'Spare Ports/Clutch Outputs', then set the PWM values under 'Lock-Up Feel Parameters'. Then you would use Amp pin 32 for PWM'd TCC control. Spare port 2 will then be on/off with the TCC, and unavailable for other uses (except for TCC 'applied' indicator light control, if you want that).
