Shifting without the clutch won't damage the trans if you match engine RPM to the speed of the car while you go through Neutral. The real trick is to get going in First, best to warm the engine up, then with a slight downhill slope, put it in First and hit the starter. I've had to do that on my Eagle at the stoplight in Medicine Hat when the clutch froze to the flywheel in a blizzard, and that was grossing over 120,000 pounds!
