Black Trans Pan GM TH400 Deep Pan

The DERALE Black Transmission Pan for TH400 is a deep-sump replacement designed for serious transmission builders, street rod enthusiasts, and high-performance mechanics who demand superior fluid capacity and cooling. This pan is particularly beneficial for those who frequently engage in extended driving, spirited shifts, or towing applications, where heat dissipation is critical for transmission longevity.

Engineered from durable steel with a black powder-coat finish, the DERALE deep pan maintains factory bolt-hole alignment while increasing fluid volume. This design allows for cooler operating temperatures and extended service intervals, which are essential for maintaining reliability in modified vehicles. The pan's construction also preserves magnetic drain plug functionality, simplifying routine fluid and filter changes.

This pan is ideal for anyone building or maintaining a TH400 transmission, from restomod builders perfecting a classic hot rod to daily-driven truck owners upgrading cooling capacity. Its design ensures that it fits within typical engine bay clearances while providing measurable fluid capacity gains that help reduce oxidation and varnish formation in the fluid.
