I have done some research on your 2004 Chevrolet Silverado 2500HD with the diesel engine and the Allison transmission. Due to the size of the coolant lines on your transmission, installation of an in-line transmission cooler would restrict the flow of fluid needed for the transmission. This restriction in fluid could result in higher transmission temperatures and result in damage to the transmission.

I would recommend the Derale Transmission Pan Cooler, part # D14207, if you have the 4L80E transmission. It will not fit other transmissions. This cooler is 4-1/6 inches deep, so this will help you determine if there is enough clearance. This cooler will install in place of your factory transmission pan. This pan cooler increases transmission fluid capacity by 4 qts,16 oz. I have attached a help article about transmission coolers.
