Our 47/48RE transmission pan is constructed of lightweight cast-aluminum for efficient heat dissipation, durability, and holds 2.5 quarts more fluid than OE. The patented sloped floor design results in 100% drainage, yet has a flat bottom for easy installation. The magnetic drain plug catches and eliminates debris from circulating throughout the transmission. The copper sealing ring provides a leak-free seal. The drain plug also uses a 1” socket for easy removal and is designed not to strip. Our 47/48RE transmission pan includes an o-ring seal with the billet lowering block to position the filter in optimum position. The 47/48RE transmission pan also comes with temperature sender plug, 3/16" Allen wrench, 1/4" Allen head driver socket, pan gasket, filter, bolts and washers.
