Review: Works just fine and quality product - I installed this in my nissan armada 2008. I had always issues with my transmission getting overheating while offroading in UAE. After this, it's just an issue in the past.
Review: Installed on 95 Mustang AODE - Fit right in the driver side of the radiator, in front of the condenser. I had to buy a pair of AN-6 to 3/8 hose elbow on order to route the inlet & outlet connections downward into the engine compartment below the radiator, and connect inline with the factory cooler. I noticed the price of the product had doubled up since I bought it couple of weeks ago!!
