My 04' Durango doesn't have the towing package. As I was changing oil last night noticed what looked like an auxilary transmission cooler in front of the radiator behind the front bumper. It had hoses running to the tranny and to the power steering pump. It was about 7 inches tall and spanned the length of the radiator. Did some D's come with extra coolers but not the towing package.

Thanks.

 

Alot of the newer Mopars come with PS coolers. MAybe they are tying in the trannys as well.
