Trans Cooler 22000 GVW 3/8 Barb Fitting

The Trans Cooler 22000 GVW 3/8 Barb Fitting by DERALE is a critical heat management component designed for trucks, trailers, and heavy-duty vehicles operating near or at their gross vehicle weight rating. Transmission fluid temperatures rise significantly under load—especially during towing, mountain driving, or sustained highway operation—and uncontrolled heat accelerates fluid degradation, reducing shift quality, fuel economy, and transmission lifespan. This cooler addresses that challenge by dissipating excess thermal energy before fluid returns to the transmission, making it essential for anyone pushing their vehicle's capabilities.

Engineered for vehicles rated at 22,000 pounds GVW, the Trans Cooler 22000 GVW 3/8 Barb Fitting features a 3/8-inch barbed port configuration that integrates seamlessly into existing transmission cooling lines without requiring thread adapters or complex fittings. The barb design creates a secure, leak-free connection when paired with appropriate hose clamps, while the aluminum core maximizes heat transfer efficiency across a compact 11.8 by 2.35 by 13.65-inch footprint. DERALE's proven thermal design accommodates high-volume fluid flow under pressure, ensuring effective cooling even during continuous operation or extreme ambient temperatures.

Diesel truck owners, commercial fleet operators, and serious towing enthusiasts benefit most from this transmission cooler, particularly those running modified trucks with increased power outputs or towing in hot climates. Installation is straightforward—plumb the cooler into the auxiliary transmission cooler circuit or factory return line by cutting and splicing existing hose runs and securing them with hose clamps to the 3/8-inch barbs. Weighing 3.28 pounds with a durable aluminum construction, the Trans Cooler 22000 GVW 3/8 Barb Fitting is compatible with most domestic and import transmission cooling systems and fits easily in engine bays, mounting brackets, or radiator shrouds using common hardware.
