aFe Power's new deep transmission pan brings performance engineering to the protection of your truck's transmission. This transmission pan has additional capacity for 3 to 4 more quarts over stock at the factory line, a magnetic drain plug and a 1/8" NPT port for your temperature sensor. Built-in internal and external fins transfer heat from the fluid to the outside air for maximum cooling. This transmission pan is constructed out of durable die-cast A380 aluminum with reinforced ribs and a wrinkle black powder-coating for maximum strength and styling. This cover fits the 727-DD transmission and requires no modification to the factory dipstick.
