Mishimoto MMOC-F Heavy Duty Racing Transmission Cooler
The Mishimoto MMOC-F combines a robust 2-row aluminum core with an 8″ slim electric fan capable of up to 1,100 CFM. Universal fitment includes mounting hardware suitable for heavy-duty, supercharged, and turbocharged setups. This design targets drivers who need maximum cooling during demanding conditions, such as towing or high-performance street use. Best for users seeking a compact, easily mounted cooler with substantial airflow. Limitation: installation may require vehicle-specific adapters or brackets to optimize fitment on some chassis.
ECMRAD 4 Rows Racing Radiator With Shroud Fans Relay Kit
The ECMRAD radiator uses a full aluminum, 4-row core with TIG-welded end tanks, delivering improved cooling efficiency and durability over factory plastic tanks. It’s a strong option for classic or performance vehicles that require a tougher cooling solution. Best for older muscle cars or vintage builds needing enhanced reliability. Better for applications where a shroud and relay kit are included for straightforward wiring. Caution: ensure compatibility with the target vehicle’s engine bay and mounting points.
JEGS High Performance Transmission Cooler (30,000 GVW)
JEGS offers a 30,000 GVW-rated cooler with a 11″ fan (500 CFM) designed for push or pull configurations. The cooler measures 11″ x 14″ x 3.75″ and uses -6 AN connections for robust plumbing. This setup is well-suited for users needing a proven, mid-size cooler that can be oriented in either direction depending on space constraints. Caution: higher amp draw may impact electrical systems in smaller vehicles.
American Volt 30 Row Aluminum Engine Trans-Mission Cooler Kit
This 30-row aluminum cooler with 50,000 BTU per hour capacity targets high-heat scenarios and demanding towing. With 6AN end fittings and a 90-watt fan drawing 7.5 amps delivering over 513 CFM, it suits trucks and vans where maximum cooling is essential. Best for heavy-duty applications where wheelbase and radiator clearance allow a larger core. Limitation: higher electrical load may affect charging systems in older vehicles.
EGINCOOLER 4-Row All Aluminum Radiator With Built-In Trans Cooler
The EGINCOOLER 4-Row radiator offers a crossflow core with 30%+ cooling efficiency over stock radiators. Built with 100% AA5052 aircraft-grade aluminum, it emphasizes durability and corrosion resistance. It includes a shroud and relay kit for straightforward installation. Best for show cars and daily drivers needing reliable cooling with a classic aluminum aesthetic. Caution: verify fitment due to variant engine bay configurations and nearby components.
Buying Guide
What to consider when choosing a built-in fan transmission cooler:
- Cooling capacity: Look at CFM ratings and BTU capacity relative to your vehicle weight, drivetrain demand, and towing load. Higher is not always better if it doesn’t fit the space.
- Core construction: Aluminum cores with TIG-welded end tanks resist corrosion and handle heat better than plastic tanks. All-aluminum builds offer durability for harsh conditions.
- Fan configuration: Inline versus integrated fans; check if the fan is push or pull capable and whether a shroud is included to maximize airflow.
- Fitment and mounting: Universal-fit units require compatible brackets and space. Vehicle-specific kits save installation time but may be harder to source.
- Electrical load: Fans draw amperage; ensure your vehicle electrical system can supply the required current without impacting other accessories.
- Installation scope: Some units require minimal drilling, while others may need custom brackets. Review mounting hardware inclusions and relay kits.
Frequently Asked Questions
- Do built-in fans significantly improve transmission cooling? Yes, integrated fans add active airflow that helps regulate temperature under high-load conditions and reduces heat soak during towing or high-speed driving.
- What size fan is best for my vehicle? Fan size depends on space and core dimensions. Larger fans (e.g., 8 inch or 11 inch) move more air but may require more mounting space.
- Is aluminum better than copper for transmission coolers? Aluminum cores are common for automotive coolers due to strength-to-weight ratio and cost; copper offers high conductivity but is heavier and more expensive.
- Can I install a transmission cooler with a built-in fan on any vehicle? Most are designed for universal or broad fitment, but verify space, mounting points, and clearance for routing hoses and wiring.
- Do these coolers require professional installation? Some installations are straightforward with basic tools, while others may benefit from professional mounting and wiring to ensure electrical safety and optimal airflow.
- How do I choose between a higher GVW cooler and a more compact unit? Higher GVW units are designed for towing and heavy-duty use. Choose based on your typical load, temperatures, and available engine bay space.
