Transmission Pan - Heavy-Duty Cast Aluminum There's no need to discard the filter pan assembly every time you service your transmission. PPE has engineered an exclusive removable and replaceable fluid filter and permanent replacement pan made from cast aluminum. This eliminates the high cost of regularly replacing the factory pan. Now simply remove, replace filter and reinstall. Holding 1.5 quarts of extra fluid, the high-strength aluminum features external cooling fins for optimal heat dissipation. Cooler fluid lubricates better which helps increase transmission service life and reduce service costs. The PPE Heavy-Duty Aluminum Transmission Pan also features a high-powered Neodymium magnet equipped drain plug to keep harmful ferrous metal contaminants out of the transmission internals.
