Trans Cooler Max-Cool 4x11x3/4

The Trans Cooler Max-Cool 4x11x3/4 from TCI is a compact plate-and-fin transmission cooler engineered for builders and performance enthusiasts who demand reliable fluid temperature control without sacrificing underhood real estate. Whether you're upgrading a street rod, handling increased torque from a modified engine, or pushing a transmission harder than stock, this cooler solves the thermal management challenge that can degrade shift quality and shorten fluid life.

Heavy-duty street driving, towing, or aggressive track use all generate excess heat that factory cooling alone cannot handle—this is where a dedicated aftermarket cooler becomes essential. Measuring 10.05 inches in length with an 11-inch width and 3/4-inch core depth, the Trans Cooler Max-Cool is designed to fit tight engine bays while delivering efficient heat rejection through its aluminum plate-and-fin core construction. This design maximizes surface area contact with cooling airflow, allowing hot transmission fluid to shed temperature quickly as it cycles through the core.

The compact footprint—weighing just 2.63 pounds—means minimal weight penalty, and the direct-bolt installation integrates seamlessly into most custom cooling loops without requiring extensive fabrication or plumbing rework. Mechanics and transmission specialists favor the Trans Cooler Max-Cool for custom builds where space constraints or aesthetic considerations eliminate larger cooler cores as options. It pairs well with modified automatic transmissions, ensuring optimal performance under demanding conditions.
