Truck was parked for about a year. Got it tagged and inspected 2 days ago . It ran just fine last year when i parked it but now that it is running again, the transmision is shifting a lot and the truck is over heating. Uses about 3 quarts of trand fluid a day but i dont see it leaking out anywhere. However,,,the radiator looks like it has oil or transmission fluid mixed in it,,,,in the radiator .when i look in it. It also looks foamy white ???? Could trans fluid be getting into the radiator ? Is that possible ? And why would it ?
