I have a 2002 Durango SLT 2WD with an automatic transmission. It makes a pretty loud horrible grinding noise for a few seconds when it is shifted into gear. I was concerned so I brought it to the dealer. He told me that it is normal and it is the solenoid somethig? ratcheting. Apparently this is something that all the new Dodge transmissions have. It supposedly helps in providing smoother shifting. It apparently happens when the transmission is shifting through the different gears in drive too, but it is harder to hear. Does anyone know what exactly this solenoid thing is and what it really does? And is this noise really normal for the new Dodge trannies? I will make sure that I get it in writing from the dealer that this noise is "normal", just in case.
