Just finished the torque converter lock up switch and must say that this is awesome. I installed mine with a momentary push button switch mounted to the gear shift lever, so I can operate it with my thumb. This isn't something that I will be using for daily driving but will use it for sled pulling and drag racing.

The truck accelerates so much faster now, I just can't figure out why I haven't done this mod before now. I have only done a few test runs so far but it is working perfect! Build a little boost, take off in first, shift to 2nd, hit the button and hang on thru OD. Too much fun!
