Never had a problem with this vehicle in 9 years, put it up for sale 10 days ago and while a fellow was looking at it today he opened the rad cap and says there is oil in the radiator. Where could this have come from? No driving issues at all - last oil change about 3,000 km ago. Different people have been looking at it. Will flushing it be enough? Thanks for any insight you can give me in to this problem that came out of nowhere. Could someone have put some oil in it - is it safe to drive?

An internal tranny cooler failure may be the cause
check if low on tranny fluid
