as i was working on the seeming endless task of hose replacement due to another hose rupture...i decided to flush out the overflow tank,as i run my finger around the top ineer part of it i got a blackish slime.looked like old motor oil to me..could it be the trans cooler line oil seeping into the coolant at the bottom of the rad? i see no discoloration in the trans or motor oil either....
