Our Hi-Tek deep transmission pans are constructed from A356-T6 hardened aluminum and are cast with integral cooling fins for maximum temperature reduction and strength. The deep pan design increases fluid capacity by 3.82 quarts over the stock O.E. (original equipment) pan. All of these features combine to help dissipate heat quicker netting lower transmission and fluid temperatures, leading to a prolonged transmission life. Other features of this popular pan include a drain port with a magnetic drain plug for clean and easy servicing. Also includes a 1/8-inch NPT (national pipe thread) temperature sensor port for easily adding a temp gauge to monitor transmission temperatures while daily driving, towing, or racing. Includes detailed instructions for easy installation.
