2014 Chevrolet Silverado 3500 - Derale Dyno-Cool Tube-Fin Transmission Cooler Kit - Class IV - Economy

  • Tube-Fin Cooler
  • With 11/32 Inch Hose Barb Inlets
  • Derale
  • 15-1/4W x 10T x 3/4D Inch
  • Standard Mount

15-1/4" Wide x 10" tall x 3/4" deep, reliable, all-aluminum tube-and-fin cooler extends the life and improves overall functioning of your Chevrolet Silverado 3500's transmission.


  • Improves functioning and overall performance of transmission
  • Extends life of transmission and prolongs period between necessary fluid changes
  • Cuts down on heat-related failures
  • Agitates fluid with built-in, embossed turbulators for more efficient cooling
  • Constructed of durable, lightweight aluminum
    • Thermal-conductive metal provides excellent transfer of heat
  • Includes:
    • High-temperature, OEM spec hose with stainless steel clamps
    • Nylon mounting rods
    • Insta-dapt radiator adapter
  • Recommended for full-size cars, trucks and SUVs
  • Imported


  • Inlets: 11/32" hose barb
  • Overall dimensions: 15-1/4" wide x 10" tall x 3/4" deep
  • Core width: 12-1/4"
  • Distance between inlets: 8-3/4"
  • 1-Year warranty

Note: The Derale Insta-dapt radiator adapter fits most vehicles with 5/16" transmission lines, but not all. In some cases, additional fittings or alteration of the OEM lines or hoses may be required for installation.

Perhaps the simplest type of heat exchanger, the tube-fin effectively cools a variety of automotive systems. The concept is simple: Fluid cools as it travels through the core by transferring heat out to the fins. The fins then provide the surface area necessary for sufficient heat exchange to take place, allowing the heat pulled from the fluid to dissipate into the surrounding air. Quick, easy and effective.
