any overheating? probably not.
-just change your engine oil. make sure it's not discolored (like chocolate milk). that would indicate coolant or some other watery substance getting into your oil - which could be a cracked engine block (very expensive).
- otherwise, highly likely, your tans oil cooler passage (inside the radiator) is busted. check your transmission fluid for the same. have the transmission oil changed anyway. all you have to do is bypass the transmission oil cooler in the radiator by installing an external transmission oil cooler. bout $25 comes with instructions, very easy to install. 2 ways to install it. Follow the instructions to install it without going thru the radiator. Go to a hardware store and get 2 screws/plug to plug up the holes now not occupied on your radiator. Make sure to use teflon tape or thread sealant. Guys at the auto store can help further. It's not very difficult.
