Probably the trany cooler in the rad has let go. If this is the case then the coolant is in the trany also. check the trany for coolant and if it is you will need a trany very soon. I've tried flushing the trany when this has happened in the past and have yet to save a trany. Usually within 3-6 week the trany stops working.
I'm not a mechanic / technician but I believe if antifreeze is getting into the engine oil it is because of a bad head gasket , or perhaps the head has warped
no but antifreeze in oil will eat the bearings
No, oil is lighter than antifreeze.
NO! Take it to a mechanic immediately. Call AAA at once, if you are a member. Oil is not antifreeze and antifreeze is not oil!
You should check your fluid levels, your oil and coolant.
The antifreeze/water mixture is too weak for the conditions or you have engine oil or trans fluid mixing with it
This means that there is oil getting in your antifreeze. More than likely you have a blown head gasket. Stop driving this vehicle until you have this repaired.
Look at the oil on the dipstick. If you have antifreeze leaking into the crankcase the oil will be milky.
A bad head gasket is the most common cause of antifreeze mixing in the oil. The antifreeze will dilute the oil and it will eventually cause your engine to seize up.
You possibly have an internal water leak in the engine, ergo, a cracked block.
Intake gaskets have failed.
A bad head gasket , warped head , cracked block etc.
