Our 68RFE transmission pan is constructed of lightweight, cast-aluminum for efficient heat dissipation, durability, and holds four quarts more fluid than the OE version. The patented sloped floor design results in 100% drainage, yet has a flat bottom for easy installation. The magnetic drain plug catches any possible worn gear material, keeping the fluid at its best while creating a leak proof seal. The drain plug uses a 1" socket for easy removal and is designed not to strip.
