I am still working on taking my full size low mileage stock 94 Dodge V6 Automatic truck on a an extended road trip. Truck is well maintained and has no modifications. I am now thinking that I would like to pull a UHaul 5' trailer with medium weight furniture load. I plan on driving through the Dakotas through Denver onto Arizona in early fall. Would the existing OEM trans cooler be sufficient or should I be looking at installing an extra trans cooler? Or is this totally a bad idea! Thanks

 

The OEM cooler is fine, as long as you don't tow with OD on.

 

Thanks for the reply.
