GMC G3500 Automatic Transmission Oil Cooler Line

The GMC G3500 Automatic Transmission Oil Cooler Line maintains the cooling of the transmission fluid so that every shift stays crisp even when the van is fully loaded and on steep grades. The Automatic Transmission Oil Cooler Line increases the flow path unlike short radiator loops providing hot lubricant with a longer cooling time before it returns under pressure. This assembly has gained a fanatical following among GMC fleet owners as, during tough towing, it doesn't burst and stops the sturdy G3500 gearbox from starving for oil. Both the early crimped rubber hoses and the later nylon tubes will follow the same path along the frame as the Automatic Transmission Oil Cooler Line does and will fit every G3500 year. The suitability across generations means one part can swiftly restore cooling on the cargo, passenger, and cutaway versions of GMC's workhorse. Through the removal of hot fluid from sensitive clutches, the Automatic Transmission Oil Cooler Line minimizes oxidative breakdown, thus extending fluid life and delaying expensive overhauls. During the testing of the G3500, the drivers' automatic transmission shift timing was steadier on the stop-and-go loops, allowing for a smoother and seamless drive. Similarly, in the mountain routes, the cooler gauge readings reflected the truck's efficiency. This gave the driver a sense of confidence and safety. The Automatic Transmission Oil Cooler Line features internal crimps that are able to hold highway pressure and plated fittings to block rust thrown up by gravel. The installation is simple because the factory-style bends allow the Automatic Transmission Oil Cooler Line to clear crossmembers without rubbing, maintaining the clean underbody of each GMC van. Due to the viscosity consistency of the Automatic Transmission Oil Cooler Line, electronic controls on later G3500 vans engage the torque converter sooner, saving precious miles per gallon of fuel use. The heavy-duty GMC cooling system is a key asset for shuttle fleets and camper owners. It allows the G3500 to deliver consistent power while helping to protect passengers and cargo. For legendary GMC durability, opt for the factory-spec Automatic Transmission Oil Cooler Line.

Each OEM GMC G3500 Automatic Transmission Oil Cooler Line we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
