I found milky fluid in the radiator -Nissan X-trail PNT30

When i was checking the level of coolant in the radiator, i saw just at the mouth of the radiator some oily cream and for sure it was oil mixed up with water. I suspected either engine or transmission oil could have been mixed up. I checked, the engine oil was okay but the gear-box oil had same milk-like substance. I have removed the radiator from the car but what then? I need help before i call the mechanics.

The transmission oil cooler is on the lower part of the radiator. it might have a hole inside. you need to replace the radiator and flush the transmission fluid several times

Sounds like you head gasket is blown. seen this alot out of that year model sentra. have you mechanic check coolant system under pressure with the spakk plugs out for coolant in middle two cylinders, that is the most common spot for head warpage. this may be a very slow leak so it will take time to so antifreeze in those cylinders.

Good luck with the dealers they are idiots.

If the car is running, you can probably rule out a head gasket. And even if it were a head gasket problem, you'd probably see the coolant level drop and have white smoke coming out of your exhaust. Have you removed the radiator cap and checked the fluid level inside the radiator? The coolant recovery tank is usually connected by a rubber tube to a vent on the side of the radiator fill mouth, and nothing flows through that tube unless the cooling system pressure increases beyond the pressure rating of the radiator cap, or radiator coolant level drops below the full level, in which case additional coolant from the recovery tank will be drawn into the radiator. This does not normally happen until the engine reaches normal operating temperature and the thermostat has opened, allowing coolant to flow through the radiator in order to keep the coolant for overheating. Again, check the radiator level. If it's OK, don't worry about it.

Shift solenoid

when vehicle is cold, check your coolant in radiator. make sure its GREEN not milky / light coffee color. If milky, you need new trans and radiator. Nissan extended warrantee for radiators. the radiator cooler fails and coolant will mix with trans fluid and your trans is junk. Nissan has program going where you will pay certain amount of money depending on your milage. start with checking coolant fluid color and let me know.

How to replace a A/T over run clutch solenoid on a 2006 Nissan frontier truck

what is wrong with the trans? i would start with checking your coolant in radiator and overflow bottle. let truck cool off and check coolant. make sure its nice and clean and green in color. not milky white. start there and let me know. we have seen radiator issues where coolant mixes with trans fluid and destroys trans. other than that those transmissions are pretty bullet proof. if your coolant is milky color, then that is a big problem. you will need new trans and radiator replaced. and to answer your question, the solenoid pack is inside of the transmission bolted to the valve body. you will need to open the unit from the bottom and replace solenoid pack.start with checking coolant first.

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.

Antifreeze has a white millky substance to it especially in coolant bottle and in hoses. Mechanic say that radiator is failing. Is this true?

Check the oil and also transmission fluid, one of them should also be milky. If it's the oil that is also milky then most likely cause is blown headgasket. If it's transmission fluid, then the radiator probably has failed in the transmission cooler section. If the transmission fluid is milky, then you also need to have the fluid flushed and the trans. filter changed after fixing the radiator.
