During my research I found that the Nissan Pathfinder had all kinds of issues with a transmission cooler located inside the radiator. After my flush in the 2011 Focus i saw that it also had the cooler inside the radiator. I just have a generic question.... is this now a staple of engineering? The pathfinders would eventually develop a leak in the transmission cooler and expose the transmission to antifreeze causing catastrophic failure. My thinking is to reroute the lines to a cheap transmission cooler located in front of radiator...and just by pass the in radiator cooler... just for peace of mind.
