in my old car with an auto it would go drom reverse to neutral without pushing the button and from nutral to drive without pushing it, also it would go from drive to neutral, and up only from the lower gears without pushing the button, on one or two occasions (when i was running REALLY low on gas) i stuck it in neutral on the freeway, and just reved the engine up to the right speed and put it back in drive, never did the car any harm but its probably not a good idea........
