Hi guys, just curious if anyone has experienced bad gas mileage after installing a transcooler in their altima. I have an 08 altima and I've recently installed a transcooler to help with the whining and slipping. I've noticed a big decrease in gas mileage after installing it. It used to take a quarter of a tank for a round trip for work. Now it takes a quarter for one way trip to work since installing the transcooler. Everything has been constant (same gas station, fuel grade, round trip mileage, low A/C usage everyday). FYI, I installed the return line from the radiator to the transcooler and then to the transmission. Any inputs or suggestions are welcomed.
