The radiator has an internal trans cooler that must be leaking, the radiator needs to be replaced and the cooling system flushed of all the trans fluid. Usually the radiator hoses and hoses going to the heater core will need to be replaced because the trans fluid will soften the rubber and make them swell. Good luck, Honda Al

I recently replaced my intake gaskets and after repairs im having transmission up shifting problems.


Check your Radiator coolant. If the coolant looks like chocolate milk, you have a cooling system leak into the transmission oil. Frequently misdiagnosed as engine oil mixing with coolant.

Coolant looks like chocolate milk, burning smell


You may have a blown head gasket allowing coolant to contaminate the oil. This an expensive fix (likely $1500 +) as you will likely need to replace one or both head gaskets.

97 mercury mountaineering has oil in the radiator and coulant. Help please!


OK, lets figure out what's happening here. You are seeing "oil" in the radiator and coolant. Chances are it is not engine oil. The inly way engine oil can get into a radiator would be if a head gasket was blown. Even then, oil at those locations is not under as much pressure as the coolant is, so when a head gasket blows, what usually happens id that the coolant ends up in the motor oil and oil pan. Verify this by looking at the dipstick to see if it is extremely full. The oil could look like choclate milk. Also, open the oil filler cap and look for signs of chocolate brown goop. I'm betting you won't find that. This is good, but also bad. What you probably have in you coolant is transmission fluid. The transmission oil is circulated through a cooler located inside the radiator. If this cracks or breaks the transmission oil can leak into the coolant. However, at different times the transmission oil and the coolant are at odd with one another pressure-wise. This means that if you have transmission oil in the coolant, you probably have coolant in the transmission oil. This is very very bad, You will need to have the transmission serviced and possible overhauled to repair the damage. You will also need to flush the trans oil from the coolant system. This will require you to replace the radiator, ALL HOSES as well. Coolant hoses do not play well with transmission fluid . The inside of the hose sort of melts and gets real soft and gooey. Changing the hoses and radiator and flushing the motor should work once the transmissionhas been serviced.

Transmission oil found in radiator


there is a cooler for the trans fluid that runs threw the f the radiator the cooler splits and trans pressure being higher while running pushes into the coolant how ever as it cools down the coolant pressure can push the coolant into the trans so see if the trans fluid looks like a straw beery milk shake if so try and keep flushing the trans until the fluid is clean and fresh if the trans makes it threw the coolant then you will need to flush the cooling system i use pinesol it breaks down the oil

Transmission is stuck in 3rd gear. starts in 3rd and does not shift


check your coolant fluid in the radiator and coolant pressure tank on side of the fender. nissan has some issue where coolant mixes with trans fluid in trans and the transmission goes south. if your coolant is not nice and green, than it mixed with trans fluid and your trans along with the radiator will have to be replaced. also check your trans fluid and make sure its nice and red, not pink and milky like strawberry milk. that is another sign of radiator cooler failure. start there and let me know what you find.

Looses transmission fluid, but their are no leaks


If it's losing tranny fluid and there are no visible leaks externally, try looking in the radiator and seeing if it looks like chocolate milk in there.More than likely you blew your transmission cooler which is built into the radiator, and that has been mixing with your engine coolant.Get back to me, I hope I could help..Thx,

Crankcase vent hose, broken, yellow fluid


The crankcase vent hose vents unburned fuel and oil fumes to prevent explosion in oil pan. The combination can result in a yellow or lite chocolate milk color if moisture is also present. These hoses harden over time due to the heat of these fumes and engine heat much like your vacuum hoses that harden.

Why does the radiator fluid in my 1991 buick regal look like chocolate milk?


1-If you open your oil cap and seeing a milky stuff at the inside cap, then there is a leak in head gasket. coolant mixed with oil through head gasket leak then vaporize leaving the milky stuff at your cap. 2-If you don't see it then there is possible transmission get into water. When you are running, the pressure from transmission is higher than coolant pressure so it leaks into your coolant thru transmission cooling coil in the radiator. 3-Need to address this as soon as possible since chance of car not running in the middle of a trip is high also consequences of problems are more costly. Good luck.
