Mark,

going thru the same thing with my car. I 'wish' my leak was due to the radiator but it's from a 'small' head gasket leak. It's posted under another thread.

Look very carefully at the oil in the coolant. If it's red tint, it's a radiator/tranny cooler leak.

To see this for youself, get a few drops from your tranny dip stick and drop it into 'shot glass' of coolant. It will have a DEFINITE red tint.

Do the same with engine oil from the dip stick. If it's brownish as you claim, it's a head gasket leak. Period!
