When I serviced my radiator I found out that there is a sticky oil brownish in color that stick on the radiator hose .i was guessing if that oil is from the engine but the engine oil is black.Is it possible that my ATF oil leak inside the radiator ? Because there is oil cooler inside the bottom of the radiator. Tks for helping more power....

Yes they can leak internally and allow coolant and ATF to mix.
