Holley's Hi-Tek deep transmission pans are constructed from A356-T6 hardened aluminum and are cast with thick internal and external fins adding additional strength and increased cooling properties. The deep pan design increases fluid capacity by 3.67 quarts over the stock O.E. (original equipment) pan. All these features combine to help dissipate heat quicker, netting lower transmission and fluid temperatures, prolonging transmission life. Other features for this popular pan include a drain port with magnetic drain plug for clean and easy servicing. Also includes 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.
