I put transmission fluid in 3 day's ago and now it's empty. Also my coolant

P0455 and P0442 do NOT indicate coolant leaks. They indicate leaks in the evaporative emissions system.These trouble codes have zero to do with your transmission fluid concern, but are a stand alone issue that should be diagnosed. Naturally, your transmission fluid situation is more urgent. A physical inspection will be required to determine the source of the leak. You indicated putting coolant in -- where and why? How are you adding transmission fluid? Is your transmission dipstick currently registering no fluid on it?

Those engine codes are not for coolant. A qualified tech needs to look at your vehicle. Possible cooling system pressure tests and inspection of the transmission including installation of dye to pinpoint leaks
