Derale Performance Fluid Cooler and Fan
Best for versatile installation, this plate-and-fin cooler offers multiple inlet/outlet configurations, including 5/8-18 in female O-ring connections and 6 AN adapters. It is designed to mount anywhere space permits and has a compact footprint suitable for many vehicle layouts. Ideal for buyers seeking a universal solution that fits a wide range of transmissions. A potential limitation is that precise mounting can require careful measurement and plumbing compatibility with existing lines.
American Volt 30 Row Engine Trans-Mission Oil Cooler
This 30-row aluminum cooler targets heavy-duty applications with an included 6AN end fittings kit and a 90-watt fan designed to deliver up to 50,000 BTU per hour and over 513 CFM. Best for tow rigs, heavy trucks, or vehicles that endure repeated high-load conditions. Choose this if you need robust cooling under demanding use; it may be overkill for light daily driving and adds weight and space requirements.
Mishimoto MMOC-F Heavy Duty Racing Cooler
Designed for universal fitment with comprehensive mounting hardware, this Mishimoto unit emphasizes enhanced cooling performance. The 8″ slim electric fan can deliver up to 1,100 CFM, helping to maintain low transmission temperatures under demanding conditions. It’s best for users seeking strong cooling in high-stress environments; installation may require precise alignment with vehicle components and secure mounting to avoid vibration.
Enignelooc Transmission Oil Cooler Shroud Fan
This cooler, shroud, and fan package supports up to 40,000 GVW and measures 8.5″ x 22.75″ x 1.25″. It is positioned for car, van, light truck, RV, and towing applications that require reliable cooling without heavy-duty modification. Best for mid-range towing and daily drivers that need added protection. A limitation is the GVW specification—it may not be suitable for very heavy commercial work beyond the stated rating.
JEGS High Performance Transmission Cooler
Featuring a 30,000 GVW rating and a fan usable as a push or pull setup, this cooler measures 11″ x 14″ x 3.75″ with a 11″ diameter fan delivering around 500 CFM and low 5-amp draw. This option suits buyers who want a solid balance of space efficiency and cooling power at a more accessible price. It’s best for sport and street vehicles that see spirited driving but aren’t limited by space constraints; it may require careful airflow planning for optimal results.
Buying Guide
What should you consider when choosing a transmission cooler with a fan?
- Cooling capacity: Look at BTU per hour or CFM ratings to match your vehicle’s load and climate. Higher numbers improve protection under heavy use.
- Inlet/outlet fittings: Ensure compatibility with your existing lines (AN adapters or O-rings). Universal options offer flexibility but may require additional fittings.
- Mounting space and weight: Larger coolers offer more cooling but require adequate space and may affect weight distribution.
- GVW rating and application: Some coolers are tailored for trailers, RVs, or trucks; verify the intended vehicle class and towing needs.
- Electrical requirements: Fans driven by electric motors draw current; confirm available power and wiring in your install plan.
- Durability and materials: Aluminum cores are common and resist corrosion; consider the environment and maintenance needs.
Practical wiring and installation considerations
- Plan hose routing to minimize bends and pressure drops that reduce cooling efficiency.
- Protect wiring from heat and vibration with proper loom and secure mounting points.
- Use appropriate clamps and hardware to prevent leaks at connections and adapters.
FAQ
- Q: Do I need a transmission cooler with a fan for daily driving? A: A fan-assisted cooler can help in warmer climates or when towing, reducing transmission heat buildup during extended periods of high load.
- Q: Is a higher CFM always better? A: Higher CFM improves cooling but requires space, airflow, and power; assess real-world fit for your setup.
- Q: Can I install a cooler without professional help? A: Many kits are designed for DIY installation, but professional help is advisable for complex plumbing or vehicle-specific mounting.
- Q: Will a bigger cooler fit my transmission cooler port? A: Check inlet/outlet sizing and ensure compatibility with your hoses or adapters before purchase.
- Q: How do I know if I need a shroud? A: A shroud improves air delivery to the fins; if the fan is drawing air from a wide area, a shroud can boost efficiency.
- Q: Are these units suitable for all climates? A: They perform best where ambient temperatures or towing loads raise transmission temps; extreme conditions may require higher-capacity options.
