Started!

After Quite a bit of searching I couldn't find out what the function of the loose cable is. I read about the 47rh transmission quite a bit. The only interaction between the first three gears and the engine are via the TV cable. I read up quite a bit about the TV cable and its adjustment. The is a button at the end of the housing near the end of the throttle cable(throttle cable shown above)that allows adjustment of the throttle cable. You can push the button in and slide the TV cable housing forward (to allow sooner shift points) or backward (to allow later shift points). I moved the housing forward about 3/16 " and test drove the truck and it shifted as it should. The truck still jumps out of overdrive as soon as you back of the pedal (even slightly). Being that over drive is electronically controlled we will address that issue by replacing the TPS sensor with a potentiometer which will allow us to determine when the truck will shift in or out of overdrive.  
If you don't stand for something you will fall for anything
