Why would my antifreeze have oil or transmission fluid in it?
About a year ago I replaced the radiator&put in a refurbished one.Around the same time I had to get the transmission rebuilt.Its ran great up untill a month ago,it overheated,so I checked the antifreeze level in the resivore & noticed it had a dark oily substance all over the inside of the resivore.I dont have any oil leaks im aware of.
Any info. or ideas on what I should or could do would really be appreciated.
Thank You,Mark S.
