After reading your post, it sounds like you may have a bad motor mount. The motor mounts are set in rubber. If the rubber wears out, you can actually feel the engine vibration through the frame of the vehicle.
You mentioned a concer regarding the transmission. If it only happens at an idle, I really don't feel it is related to a transmission problem. The clicking noise doesn't sound like anything to worry about either. They tend to make a clicking noise when they are shifted. Actually, a broken or worn motor mount could make that noise worse. Have the motor mounts checked. Or you can do it yourself.
Have a helper get in the vehicle. Start the engine, open the hood, make sure the parking brake is on and tell the helper to keep his foot on the brake. Place the transmission in drive. While holding the vehicle stationary with the brakes, push on the gas slightly. If you have a bad or broken mount, the engine will lift. NOTE: If it moves more than an inch in drive or reverse, chances are a mount is bad.
Let me know what you find.
