Covered by a limited lifetime warranty. Transmission Pan for 8HP70 / 8HP75 - Heavy-Duty Cast Aluminum Factory plastic pans are discarded each time you do an 8HP70 transmission service. Upgrade to a permanent solution. PPE has engineered an exclusive cast aluminum pan with a replaceable filter, which means unlike the factory part there is no need to discard the factory pan assembly every time you service your truck's transmission. This eliminates the high cost of regularly replacing the factory pan. Now simply drain, replace the filter and refill. PPE's Heavy-Duty Transmission Pans hold extra fluid and are cast from high-strength aluminum for optimal heat dissipation. This pan features internal heat sinks and external cooling fins. These cooling fins, combined with cast aluminum construction, promote reduced transmission fluid temperatures. Cooler oil 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.
