Question:

Does the # D13960 replace the existing transmission cooler or should this be installed inline to be used with the factory cooler?

It's definitely not abnormal for your transmission fluid to heat up while towing, especially when you're going up hills that force the truck to work a lot harder. To help with this adding a transmission cooler like you mentioned is a great idea.

For your 2005 Chevy Silverado 2500HD I highly recommend the Derale Hyper-Cool Remote Transmission Cooler Kit w/ Fan # D13960. This cooler will do a great job of improving the performance and function of your transmission with its reversible tornado fan to ensure optimum airflow and stacked-plate design to help with heat transfer. The remote cooler can be mounted anywhere where space permits on your truck. It measures 13 inches wide, 10 inches tall, and 5-5/8 inches deep.

If your 2500HD has the 6.0L engine you will need the Adapter Fitting # D13035 to help with installation.

Another option is with a pan cooler like the Derale # D14207. This will simply replace the existing oil pan on your Silverado to increase its fluid capacity. This along with the built-in turbulator tubes for better airflow helps to keep the transmission cooler.

Between the two options I do recommend going with the Derale Hyper-Cool Transmission Cooler # D13960 as this will provide much better cooling for your application.

The transmission coolers we have available like the Derale Hyper-Cool Remote Transmission Cooler # D13960 are designed to supplement the factory cooler in the vehicle and work along with it. They are not designed to replace or completely bypass the factory unit. You will get the best results by keeping your factory cooler in place and installing the Derale Series Transmission Cooler to provide additional cooling.
