I just replace my transmission two weeks to go, and every time I stop I smell antifreeze and it looks like smoke or something coming out from the hood and then sometimes it come into the car from the vents??? I open the hood the majority of the smoke was coming from the driver side under the hood!!! It's not over Overheating in the reservoir is filled!?!? I have a 2007 all wheel drive SEL

 

You should never have to smell anti freeze unless something is leaking. The smoke you see is the tell tale clue. If you cannot determine where the leak is located , just have someone that can use a cooling system pressure tester, where pressure is applied to the cooling system at the fill location usually up to 15 psi. The leak is usually easy to spot with the pressure applied. Repairs can be done after the leak is located.
