• Description:

  This genuine Ford JL3Z-7H255-A is an automatic transmission oil cooler hose and line assembly for the 2018 through 2020 Ford F-150, cataloged by Ford as Hose - Oil Cooler on the transmission cooling circuit. It carries automatic transmission fluid to and from the cooler so the heat produced by the ten speed automatic is shed and the fluid returns at a controlled temperature, which protects the internal clutches and keeps shifts consistent under load and while towing. The assembly combines formed tube and flexible hose with the correct fittings and seals to make the connection in the cooling loop. Owners replace this line when it develops a leak at a crimp or fitting, the hose section cracks or swells with age and heat, or a corroded tube begins to weep, with the usual signs being reddish transmission fluid spots under the front of the truck, a gradually dropping fluid level, and in worse cases elevated transmission temperature or a burnt fluid odor. A neglected cooler line leak can lower fluid level enough to damage the transmission, so timely replacement is important. Installing the correct Ford line ensures the routing, length, and fitting sizes match the factory circuit without adapting. Replace any single use O-ring seals at the connections, refill with the specified Motorcraft transmission fluid, and check for leaks after the repair. As a genuine Ford component it restores proper transmission cooling and sealing. Confirm your engine and cooler configuration before ordering so the line matches your build.
