Transmission Oil Cooler2 3 Row 3/8in Barb

The FLEX-A-LITE Transmission Oil Cooler2 3 Row 3/8in Barb (Model 113807) is a plate-and-fin aluminum transmission fluid cooler designed to maintain optimal fluid temperatures during sustained driving, towing, or performance operation. This three-row cooler combines compact dimensions with effective heat dissipal, making it an ideal upgrade for vehicles that experience elevated transmission temperatures under load.

The cooler features 3/8-inch hose barb inlets and outlets, allowing straightforward integration into existing or new cooling system plumbing. Constructed from aluminum in natural finish, the cooler weighs 2.29 lbs and measures 11.5 x 2.3 x 14.1 inches, fitting neatly into engine bays where space is limited. The plate-and-fin core design maximizes surface area for efficient fluid cooling while maintaining a compact footprint—a critical balance in retrofit situations where cooler placement options are constrained.

This transmission oil cooler serves builders and technicians working on street performance vehicles, trucks used for towing, and any application where factory cooling capacity proves insufficient. Sustained high temperatures degrade transmission fluid viscosity and accelerate internal wear; adding a dedicated cooler extends fluid life and improves shift quality and reliability under demanding conditions. The three-row configuration balances cooling capacity with pressure drop, making it suitable for both street and light-duty hauling without over-cooling in seasonal or low-load scenarios.

FLEX-A-LITE's established reputation in thermal management products reflects decades of OEM and aftermarket cooling solutions. The 113807 represents a proven design, with straightforward barb connections that integrate into hose-based systems common in many modern transmissions and retrofit applications.
