EVIL ENERGY 5/16-inch Transmission Oil Cooler Kit — 6-Pass Aluminum Tube-and-Fin, Silver, 15.66×7.5×0.75 in

EVIL ENERGY's 5/16" 6-pass aluminum transmission oil cooler is a compact, universal kit that lowers automatic transmission fluid (ATF) temperature by routing fluid through six tube-and-fin passes for improved heat dissipation.

This universal trans cooler kit is engineered for vehicles with 5/16" internal diameter transmission lines and designed to fit where airflow is available. Constructed from lightweight aluminum alloy with a tube-and-fin core, the 15.66" × 7.5" × 0.75" cooler pairs with durable CPE hoses rated for 145 PSI working pressure and a wide −40°F to 257°F temperature range. The package includes mounting hardware and a straightforward instruction sheet so you can place the cooler where it receives steady airflow, such as in front of the radiator or condenser.

How does the 6-pass tube-and-fin design reduce ATF temperature?

The 6-pass layout forces fluid to travel through multiple narrow tubes while fins increase surface area for air contact, promoting faster heat transfer away from the fluid. More passes mean longer fluid residence time and more consistent cooling across the core.

• Six internal passes increase fluid exposure to the cooled tube surfaces.
• Aluminium tube-and-fin core provides high thermal conductivity and low weight.
• Fins channel airflow to accelerate heat dissipation during driving.

Will this cooler fit my vehicle and how do I check compatibility?

The kit is universal for systems using 5/16" ID transmission cooler lines, but you should confirm available installation space and line fittings. Measure clearance in front of the radiator or behind the bumper and verify your lines are 5/16" to ensure a correct match.

• Core dimensions: 15.66" × 7.5" × 0.75" — check available mounting area.
• Line requirement: 5/16" inner diameter transmission cooler lines.
• Includes CPE hoses and mounting hardware for typical installations.

What materials and operating limits should I expect?

The cooler core is aluminum alloy for efficient heat transfer and corrosion resistance, paired with CPE hoses that withstand typical transmission system pressures and a wide temperature span. These materials balance durability with lightweight construction suitable for aftermarket retrofit use.

• Core: aluminum alloy for high thermal conductivity.
• Hose: CPE material; working pressure 145 PSI, burst ~900 PSI.
• Temperature range: rated from −40°F to 257°F for varied climates.

How difficult is installation and where should I mount it?

Installation is intended to be straightforward for DIY mechanics and professionals alike; the kit ships with installation instructions and hardware. Mount the cooler where it receives unobstructed airflow — typically ahead of the radiator, condenser, or behind the grille — and avoid locations that block air movement or expose the cooler to road debris without protection.

• Mount in a high-airflow area, avoiding obstruction and excessive heat sources.
• Use supplied brackets and hardware; ensure secure hose clamps on 5/16" lines.
• Follow included instructions and route hoses away from sharp edges and hot exhaust components.

This EVIL ENERGY transmission oil cooler is designed for vehicle owners who want a compact, efficient aftermarket solution to help manage ATF temperatures. It's a practical option for daily drivers, towing vehicles, older cars with limited factory cooling, and anyone installing an auxiliary cooler with 5/16" lines. If you have limited front-end space but need improved transmission fluid cooling, this low-profile 6-pass aluminum cooler is built to fit into tight mounting locations while offering reliable thermal performance.
