SOURCE: 2002 chev venture engine light on after transmission fluid low

low transmission will not turn on the light, only a coincidence, you need to have the code read with a scan tool to fix the problem and turn off the light.

SOURCE: is transmission cooler located inside of radiator

I would not worry about antifreeze in the transmission. The pressure in the tranny cooler will not let any coolant get in. If it was leaking you would have tranny fluid in the radiator. You may have some freeze plugs that have pushed out or a cracked block or some coolant passage above the transmission. Get it pressure checked

SOURCE: Radiator fluid getting into oil

You might not notice a change in performance for a while, but the head gasket is blown and the water seeps down there at night or when it is cool. It won't do it when it is running because it gets burnt. Check your exhaust for steam, and get a compression check done, it will tell which cylinder is blown. I just had a car blow on me, ran fine for many miles, would eat coolant though. I never let it overheat, but then one day, kaboom, all done, wouldn't run again. The hole in the gasket was smaller than these letters I'm typing, and the one cylinder that blew was squeaky clean, from the steam. Hope this helps.

Pink Milkshake looking fluid in transmissiion

your transmission fluid lines run thru the radiator's transmission cooling cell. When the radiator springs an internal leak, it contaminates the trans fluid with coolant/water mix, giving it the milky pink appearance. Replace radiator and flush transmission.

I have a 1998 chevy suburban k1500. I was told the radiator didnt have the eoc but when called around for a new radiator i was told they dnt make one without the eoc. which one is correct

a radiator is used to cool the coolant as long as it has a top and bottom hose fitting in the right place for your engine and an oil cooler fittings for the transmission , there will be little difference in what ever else there is
some have a radiator cap and a hose to a reservoir and other do not have a cap as it is on the reservoir
the radiator shop will know the correct radiator to fit

Ford_v10 oil in water resiviour. with the coolant cap off and engine running there are no bubbles what else could be wrong besides blown head gasket

You may not see bubbles depending on the radiator set up. There are kits that test for exhaust gases in the radiator. If that comes back negative check if you are losing oil or transmission fluid. Oil can be a cracked block which is bad. If it's transmission fluid it could just be the radiator. Transmission fluid is run through the radiator to cool it down. That's just replacing the radiator.

Newly rebuilt transmission is found to have water in it-the rebuild shop was the last place to add fluid or to have anything to do with it. how do you think the water got in?

Hello you have water inside your transmission. Dont drive it at all it will damage the clutches internally. This is probably the same thing that caused the last transmission to go out. This may sound crazy but there is a transmission cooler built into the radiator,and once the engine gets hot it builds pressure in the radiator causing water to be pushed into the transmission cooler lines. A quick check will be just remove the radiator cap and see if transmission fluid is in the radiator. If you have acess to a radiator pressurer tester, then you can remove the cooler lines and pressurize the system no more than what is on the radiator cap and see if any coolant leaks. If so you will have to replace all hoses and the radiator. The hoses will swell up and deteriorate in no time because of the trans fluid.

Loosing water out of radiator and overflow tank has greasy look in the bottom. Also transmission fluid appears to have been sprayed over undercarriage at the rear of transmission.

You need to carefully check over the entire cooling system and engine for leaks. I can't see that far...Residue in tank is likely normal...never seen one that is clean. You don't want to see actual oil floating in there or in the radiator. Under the car, the trans fluid should be cleaned up with a rag, then run it and ...look carefully for seepage. Most common is the pan gasket or driveshaft seal, but check everything. You have the advantage can look at it, I cannot.
