First time posting here, I have a 2003 Caravan 3.3 V6 40,000 miles , it has a noticeable whining noise ,louder when cold ,the pitch of the noise dose change when going through the gears. thanks hope someone can help!!

 

It could either be the torque converter or the transmission pump. With the low mileage i'm gonna bet on the torque converter. Good Luck.

 

I have 2002 Caravan SE V6 and 43K miles. I have a simliar grinding/whining noise when I approach a stop. It starts at 20-30 mph and gets louder at a stop. It then makes a high pitch squealing noise as i am accelerating, then goes away. This noise only happens the first 15-20 minutes i drive until engine is at normal operating temp.

I appreciate the feedback...before I empty my pockets to the dealer!
