19-Row Stack Plate Trans Cooler Kit (-6AN)

The DERALE 19-Row Stack Plate Transmission Cooler Kit with -6AN fittings is a high-capacity fluid cooling solution engineered for serious transmission temperature management. This plate-type cooler delivers efficient heat dissipation through its 19-row aluminum core, making it ideal for heavy-duty driving, towing, and performance applications where factory transmission cooling falls short. The kit arrives complete with all necessary fittings and adapters, streamlining installation without requiring additional components.

The cooler features a robust aluminum construction with black powder-coat finish, delivering both durability and corrosion resistance under demanding conditions. Its compact 7.9 x 2.1 x 18.5-inch profile allows flexible mounting in tight engine bays, while the 10 AN female O-ring inlet and outlet connections ensure secure, leak-free operation under high-pressure systems. The included -6AN male adapters facilitate seamless integration with most transmission line configurations, eliminating adapter hunting and installation guesswork. At 4.2 pounds, the unit adds minimal weight while providing substantial thermal capacity improvement over single-row designs.

Transmission coolers become critical when fluid temperatures exceed 180–200°F, a common threshold for vehicles experiencing sustained load, high ambient heat, or performance driving. The 19-row stack design maximizes surface area for heat exchange, pulling thermal energy away from the transmission fluid more efficiently than undersized OEM coolers. This kit is particularly valuable for truck owners, tow vehicle operators, and enthusiasts running modified powerplants where standard cooling margins no longer apply.

DERALE is recognized in the automotive cooling category for engineering coolers that prioritize both performance and reliability. This transmission cooler kit represents the brand's straightforward approach: deliver capable hardware with complete fitment hardware, allowing buyers to upgrade cooling without guesswork or supplemental purchases.
