Russell's 15-inch heat sink transmission cooler uses a low-profile heat-sink method to reduce temperature spikes common with tube-and-fin coolers and can be mounted in multiple positions, including frame rail locations. The unit features -8 AN female O-ring ports and provides substantial cooling area to manage transmission fluid temperature. It can also be applied to reduce temperatures in power steering systems where needed.
