Torque converter lockup?
On ebay there is for sale a "torque converter lockup override module". It looks like a simple on/off switch that interrupts the wiring? Has anyone ever tried this? Do you know if it can do any damage? What would happen if you kept it manually locked when you came to a stop? Wouldn't the engine stall?

If you have a 4R70W in your vehicle-TCC lockup in 1st is hydraulically disabled via a hole in the valvebody seperator plate.You can command it locked via EEC software,but if you try to lock it via 12V to the solenoid-it won't last long-it's not designed for continuous 12V,it's a PWM device.Leaving it locked during upshifts is also very abusive to hardparts in the trans.
The 4R100 on the other hand, can be locked while in 1st, so there's a risk of stall if you leave it locked and come to a stop. I'm not 100% sure on the function of the lockup solenoid on that trans and whether it'll handle a manual lockup switch feeding it 12V continuous.
