The problem seemed to be only in cold weather and would go away once the car warmed up. Now it's all the time and quite loud.
My transmission whines all the time. 2 yrs. ago we flushed it, now it's constant on 2006 Chrysler Town & Country
Are you sure its the transmission and not the power steering? Steering in a Town and Country often gets wines. Al you can do is make sure the fluid is correct for that transmission and make sure there are no codes stored in the transmission. There is a transmission additive called Lubegaurd I lke seems to have prolonged the life of several of our customers transmissions.
