ok... I know which wire it is on the PCM... but I need to know which wire it is on the actual trans (so I can cut it for diagnostics)

Is it part of the main harness that plugs in on the passenger side towards the tail shaft? or is that only VSS? Anyone have a wiring diagram showing where the lockup wire plugs in?

This is on a vacuum modulated 4L60E

i'd like to know as well so I can do a manual lockup switch

for a lockup switch you can splice by the PCM

(not sure what year you have... I think it's the same wire for 99-02s)

on the Red PCM connector
Wire 42
TAN/BLK
422
TCC Enable Circuit

when it goes to ground the converter locks up

I need to know where this goes at the transmission though... so I can cut it and possibly rerun the wire

i have a 00 t/a as well....usually the wires don't change colors front to back of the car. Is there not a tan/blck wire on the tranny connector?

good point... I'll have to look this weekend ... guess I can't really fug anything up heh... line pressure is controlled by vacuum
