The PERMA-COOL HD Trans Oil Cooler Kit delivers serious thermal protection for full-size cars and light trucks with gross vehicle weight ratings up to 17,000 pounds. This aluminum tube-and-fin cooler addresses the root cause of transmission failure: excessive heat. When you're towing boats, campers, or heavy equipment, transmission fluid temperatures climb rapidly. The 1301 kit pulls that heat out of the system before it breaks down your fluid and damages internal components. We stock this cooler because it matches the demands of Florida drivers who tow year-round in punishing heat.
PERMA-COOL engineered this cooler with a 15-inch by 7-inch by 1.5-inch aluminum core using tube-and-fin construction for efficient heat dissipation. The 11/32-inch hose barb inlet and outlet fittings connect to the included 4-foot transmission oil hose, which handles the routing between your factory cooler lines and the auxiliary unit. Stainless steel worm gear hose clamps secure every connection point, eliminating the risk of leaks under pressure. The complete kit ships with all mounting hardware and illustrated instructions, so you're not hunting for brackets or fittings at the parts store.

Install this cooler if you tow frequently, drive in stop-and-go traffic with a loaded vehicle, or live where summer temperatures stay brutal. Position it in front of your radiator or A/C condenser where airflow keeps the core working efficiently. The unpainted aluminum finish blends into engine bay aesthetics without drawing attention. Pair it with other heating and cooling upgrades to build a complete thermal management system. For vehicles running hard in demanding conditions, the PERMA-COOL 1301 provides the margin your transmission needs to survive.
This cooler is rated for full-size cars and light trucks with gross vehicle weights up to 17,000 pounds. That covers most half-ton and three-quarter-ton pickups, full-size SUVs, and passenger vehicles used for towing trailers, boats, or campers.
Yes. The kit includes the aluminum cooler core, 4 feet of 11/32-inch I.D. transmission oil hose, stainless steel worm gear hose clamps, fittings, mounting hardware, and illustrated installation instructions. No additional parts are required for a standard installation.
Mount the cooler in front of your radiator or air conditioning condenser where it receives direct airflow from the grille. The included mounting hardware allows flexible positioning. Avoid locations behind other heat exchangers where pre-heated air reduces cooling efficiency.
This is an auxiliary cooler designed to work alongside your factory unit. Transmission fluid flows through your existing cooler first, then routes through the PERMA-COOL unit for additional heat rejection before returning to the transmission.
