2005 Pontiac Vibe 4 cyl Front Wheel Drive Automatic 88,000 miles
When I start the car first thing in the am. It makes a noise, that I can here from inside the car. It sounds like a lawnmover noise (mild). When I put the car in park the noise stops. When the care is warmed up the noise stops.
It's pretty impossible to diagnose a noise over the Internet. You really need someone knowledgeable to listen to it and isolate it down. We can advise you on the technical aspects when you have more info.
