Loosely roll up a sheet of white paper towel and dip into the coolant bottle -- pull out and unroll -- what color is the oil stain?
Reddish for tranny -- Brownish for engine
Could take the trans cooler lines off the radiator, then pressurize the radiator to 14psi -- look for coolant leaking out of the trans cooler fittings

|C130||Is there an easy way to determine if itâ€™s the transmission cooler? Iâ€™ll take a close look at it tomorrow and see if thereâ€™s visible damage from the accident. I know they replaced the piece that goes across the front end thatâ€™s right in front of the transmission cooler. Truck is lifted and most of the impact was from the underneath.|

Well, if it is the transmission cooler, I'd go ahead an plan on a trans rebuild. The clutches and bands do not do well with water intrusion. The friction material will delaminate.
Oil in the coolant will look milky, trans fluid will too, to a degree, but you should be able to see a pretty decent amount of the red fluid floating on top.

|C130||Thanks, with it being hit in the front end and transmission fluid being low Iâ€™m leaning towards transmission cooler.|

|G8orFord||Oil in coolant is usually from the oil cooler rupturing. The transmission cooler could also be the culprit, but it's much less likely.|

Oil In Coolant
04 6.0, got oil in the coolant. Truck has had head gaskets replaced, ARP studs. Truck runs perfect, zero smoke, no other indications. Son was in an accident several months ago, front end damage. Of course initially I thought blown head gasket but it just doesnâ€™t make sense. We donâ€™t tow with it and the truck is treated very good. Got to thinking maybe transmission cooler was damaged in the accident and checked transmission fluid and itâ€™s low. Would this make sense? Like I said, truck starts right up and runs fine, no other indications.
