Trans Cooler 17500 GVW 3/8 Barb Fitting

The Trans Cooler 17500 GVW 3/8 Barb Fitting by DERALE is an essential upgrade for any vehicle running sustained high-load conditions, towing operations, or aggressive driving that generates excessive transmission heat. This cooler is designed to help prevent transmission fluid degradation that can occur at temperatures above 200°F, which can damage clutch materials and reduce bearing life.

Constructed from robust aluminum, this cooler features an efficient core design that maximizes heat rejection while maintaining low restriction, which is critical for preserving transmission pressure and shift quality. The 3/8 inch barb fitting allows for direct integration into existing transmission cooler lines, eliminating the need for adapters or compression fittings that may develop leaks under vibration.

Ideal for mid-duty trucks, commercial vans, and heavily modified street machines, this cooler is commonly used for automatic transmission swaps, turbo diesel builds, and towing package retrofits where OEM cooling capacity is insufficient. Its compact dimensions (11.8 x 2.25 x 13.65 inches) and lightweight design (2.91 lbs) make it suitable for installation in tight engine bays without compromising under-hood balance.
