has anyone tried a torque converter lock up switch on our cars or tired wiring switches for manual shift... how well does it work... would it work at all... i have seen it done on my jeep before... just a crazy thought i had

I dont know why you would need a switch for it

I have a test box i built that can do all of that, Not sure why you would want to do it other wise though.
But for lockup unless a valve body mod has been done to eliminate PWM you would need to ground both the TCC solenoid and the PWM solenoid to get lockup, However doing either of these will make a code for TCC and PWM solenoid electrical.
