1998 Jeep Cherokee Question: Oil in coolant reservoir

 

Question

I had the tranny cooling radiator replaced. I was getting light-brown sludge in the rediator and reservoir. Now I have dark-brown sludge only in the reservoir; radiator seems clean ( unless the sludge settles to the bottom). What's up?

    Clean out the coolant reservoir, maybe the oil from the trans cooler settled in the reservoir.
