I have a Brown fluis in my coolant. There is no oil loss no foam on oil cap. Transmission slips a little. Is this Trans fluid in my radiator, I have no foam on my transmission fluid stick either.

The reason I asked about the trans is because the cooler is built into the radiator. I have seen them go bad and cause ATF to mix with the coolant.

As far as it being brown, if it appears there are no leaks, I would recommend having the system flushed. It could be that the coolant is that dirty or a prior owner put a stop leak in it.

let know what you find.
