The transmission is in the auto mode (D). The sound is intermittent from neutral to drive.

Has sound been in engine since you have owned it?
Replywilliebcc, August 21, 2012, 22:24Rookie
Yes, I started to hear the sound after a few days later after I purchased the car. I first taught it to be poor gas octane quality but later drove the car up hills and the sound of diesel wasn't heard. Seems to me only when the car is at low RMP when the sound is heard.
