Hughes Performance Cast Aluminum Transmission Pans are precision engineered to reduce transmission temperatures and increase transmission life span. Each Hughes Performance Cast Aluminum Transmission Pan comes equipped with cooling fins to dissipate heat faster and reduce transmission fluid temperatures. These Cast Aluminum Transmission Pans and are also designed to hold 1 to 4 extra quarts of fluid over stock transmission pans, reducing operating temperatures and further extending transmission life. Hughes Performance Cast Aluminum Transmission Pans also improve transmission case rigidity to allow more torsional twist.
