1. Derale 134000 Plate and Fin Cooler: Best Overall
The Derale 134000 is a plate and fin cooler that we found to be a top performer based on its 16,000 GVW rating and owner feedback.

Frequently Asked Questions
What size transmission cooler do I need for a 4L60E?
The size depends on your usage. For daily driving, a cooler with 15,000-20,000 BTU/hr is sufficient. For towing or performance, look for 20,000+ BTU/hr. Physical size should fit your vehicle’s available space, typically 11″x7″ to 11″x11″ for most cars and trucks.
Can I install a transmission cooler myself?
Yes, most coolers come with mounting hardware and instructions. Basic mechanical skills and tools are required. You will need to cut and splice into the transmission cooler lines, mount the cooler securely, and ensure proper airflow. If you are not comfortable, a professional installation is recommended.
Do I need a fan with my transmission cooler?
A fan is not always necessary if the cooler is mounted in front of the radiator or condenser where it gets airflow. However, for severe duty, stop-and-go traffic, or off-road use, a thermostatically controlled fan can improve cooling at low speeds.
Should I bypass the radiator cooler when adding an auxiliary cooler?
It depends. Some prefer to run the transmission fluid through the radiator cooler first to warm up quickly, then through the auxiliary cooler. Others bypass the radiator to avoid heat soak. For most 4L60E builds, keeping the radiator cooler in line helps with cold starts and provides additional cooling capacity.
How do I know if my transmission cooler is working?
Monitor transmission fluid temperature with a gauge. Normal operating temperature for a 4L60E is around 160-200°F. After installing a cooler, you should see lower peak temperatures under load. A drop of 20-30°F is typical for a well-sized cooler.
Our Verdict
After comparing specs and owner feedback, the Derale 134000 Plate and Fin Cooler is our top pick for its excellent cooling capacity and durable build. For a more budget-friendly option that still performs well, the B&M 70268 SuperCooler is a solid runner-up, especially for daily drivers and light towing.
