Hello fellow GMCers,
This is my first ever post. I bought my 1973 Painted Desert 260 6 months ago. I was excited for the prospect of a work-in-progress, but boy, I am not sure I was ready for the stress of breaking down. So I am arriving at my brothers house in Portland, Oregon and it's a narrow residential city street. I menuever the GMC across the width of the street so I can begin carefully backing into his driveway. I then put the selector in Reverse, press the gas, AND... the engine revs and goes nowhere. what the...? Back to drive... nothing? What about S and L. Still Nothing. It seems like my choices are Park and Neutral. I am now blocking the whole street from ever being used again. My wife and child and dog are all barking at me and if I can't fix it I'll have to push this sweet dream machine into the Willamette. With the help of my He-Man brother we actually pushed GMC (we call it The Gator) into a parallel parking position (the driveway is uphill, so there is no way we can push it into the driveway). And now I am here at 11 pm to make my petition before the GMC Parliament: How do I begin to tackle this problem? What is wrong? Please help me!

Cheers!
Andrew

A little helpful background on me. I am a city boy, but I am not entirely un-handy. However, I am 28 and I got my drivers license just to buy this machine, so let's just say I am a fresh face on the scene.
