Material: Most polished options are made from cast aluminum which is more durable than stamped steel and designed to dissipate heat more effectively, keeping transmission fluid cooler.
Design: The finned design increases the surface area of the pan, further enhancing the cooling properties.
Aesthetics: The polished finish provides a show-quality appearance, adding to the visual appeal of the vehicle.
Convenience: Many of these pans include a drain plug for cleaner, more convenient fluid changes, which is often missing from stock GM TH350 pans.
Capacity: Both stock capacity (around 2-2.25 inches deep) and deep sump versions are available, with deep pans holding more fluid for better heat management in high-performance applications. Note that deep pans may require a filter extension kit.
Included Hardware: Most kits come complete with a gasket and necessary mounting bolts for a straightforward installation.Â
