My tuning is a variation of the 10k mod. I built mine with a rotary switch that allows you to choose between stock, 15k, 10k, and 4.6K of resistance. Each step adds more fuel to the fire (essentially what all the expensive tuner boxes do.) I can post pics of my setup in my dash.
My TC lockup is just as simple. It's a toggle switch hooked into the TC control wire. When you ground the wire, the TC is locked up. I added a bi-color LED to the mix so you can tell when the TC is locked. It turns green when the computer locks it up, and red when I flip the switch. You can also use it to see if the computer is allowing it to slowly lock up (slip) by it turning amber. When towing, I see my tranny temps run drastically lower. You just have to make sure you unlock it before you stop... otherwise its just like stopping with a manual tranny with it in gear and the clutch engaged. :redneck:
