US Motor Works 33603 13-Row Series 9000 Plate & Fin Transmission Cooler 1/2" NPT

The US Motor Works 33603 is a 13-row Series 9000 plate and fin fluid cooler designed to reduce transmission fluid temperatures and protect your drivetrain from heat-related damage. Ideal for light to medium duty vehicles and occasional towing applications, this radiator-style heat exchanger delivers reliable, efficient cooling performance.

Built with sturdy furnace-brazed aluminum construction and 1-1/4" wide embossed turbulator plates, this cooler maximizes heat transfer while minimizing pressure drop across the unit. The plate and fin design increases surface area, allowing transmission fluid to spread across the finned channels for more efficient heat dissipation.

Key Features:

• 13-row plate and fin heat exchanger design for high cooling efficiency
• Furnace-brazed aluminum construction for strength and durability
• 1-1/4" wide turbulator plates maximize heat transfer and minimize pressure drop
• 1/2" NPT female cooler ports for easy plumbing
• Includes 1/2" NPT x 3/8" hose barb adapters
• Rated at 250 PSI working pressure and 300 PSI burst strength
• Fluid capacity: 10 oz.
• Dimensions: 9-7/8" W x 8-1/2" H x 1-1/4" D
• Black anodized aluminum finish

This transmission cooler helps prevent overheating that leads to premature transmission failure, extends the service life of automatic transmission fluid, and can improve overall shift quality. This listing is for the cooler only — no fan or mounting kit included.
