Re: How can I make a lockup switch? Find out the exact pinout number for the wire on your pcm that locks up the TC.
Spliceinto that wire with another wire, run the new wire into your passenger compartment, to a momentary switch mounted in the location you want. run the other lead of the momentary switch to a ground.
When you hit the switch it grounds the wire, and will lockup the converter.
I don't remember off the top of my head which wire it is for the '01 models.

By splicing into that wire where you can manually ground it has no i'll effects.
I used this setup for quite some time on my 4l60e with zero problems. I have a t350 now, but I still have that wire rolled and tied up behind the dash in case I ever go back to a 4l60e, and want to use it.
