Thin Line Trans Cooler Kit

The Thin Line Trans Cooler Kit from PERMA-COOL is engineered for drivers who demand precision temperature management in high-performance and modified vehicles. Whether you're pushing a built transmission hard on the street, track, or towing heavy loads, transmission fluid temperature directly impacts shift quality, clutch longevity, and overall drivetrain reliability. This compact cooler integrates into existing cooling systems without consuming excessive underhood real estate, making it ideal for engine swaps, turbocharged builds, and any platform where factory cooling falls short.

Built from lightweight aluminum construction, the Thin Line Trans Cooler Kit features a tube-type core design optimized for efficient heat rejection in confined spaces. The 11/32-inch hose barb inlet and outlet fittings accommodate standard transmission cooling lines and aftermarket plumbing setups, while the complete kit includes all necessary brackets, fittings, and hardware for bolt-on installation. Its compact 15.5 x 5 x 0.75-inch cooler body slides into tight engine bays without modification, and the natural aluminum finish resists corrosion while maintaining professional appearance—critical when every square inch of underhood real estate matters in a modified build.

This kit benefits any builder running higher-than-stock transmission pressures, extended towing duties, or spirited driving in warm climates where OEM cooling proves insufficient. Installation requires basic mechanical skill and standard hand tools—no welding or custom fabrication necessary. Compatibility spans rear-wheel-drive and all-wheel-drive platforms with transmission-mounted or remote cooler provisions; verify hose routing clearance and fitting orientation for your specific vehicle before purchase. Pair this cooler with a quality synthetic transmission fluid and thermal monitoring to maximize shift response and component lifespan in demanding applications.
