Upgraded Design & Performance

PPE designed their Heavy-Duty Cast Deep Transmission Pan with cast aluminum fins and heat sinks to enhance heat dissipation. The pan features external gussets to support the machined flange, ensuring impressive durability. Included is a high-power neodymium magnet-equipped billet 304 stainless steel drain plug with a Viton O-ring seal, along with a 9/16’’ ORB neodymium magnetic plug with Viton O-ring seals for the fluid level check port. These powerful magnets effectively capture ferrous metals from the fluid, preventing potential damage to the expensive internal components.
