Ok so i replaced the thermostat and fixed a small crack on the radiator i do have some good news off this it wont pop out of 4th anymore but it still wont shift into 4th unless warmed up but now it only takes 4-5 minutes  and before it was taking up to 15 so that is also good.....i think the radiator might have another little crack in it do you think that might have anything to do with it since its loosing pressure through there?
