Strong possibility of a blown head gasket. Either do not drive it or driver very slowly and carefully to get it checked. You dont have a blown head gasket, you have a leak in the transmission oil cooler which is inside the radiator. The cheapest way to fix it is to buy a external transmission oil cooler and hook that up to the transmission oil cooler lines which are now going to your radiator. then cap off the two ports on the radiator where the old cooler lines went. Your car will never know the difference, and your transmission will probably last longer as the external transmission oil cooler is vastly supirior to the one inside the radiator.

The most common reason would be a ruptured oil cooler in the radiator. Check to see if you have oil lines going to the radiator, if you do, you need a radiator. Also, don't forget to change the anti-freeze because it will be contaminated. Don't forget to check your transmission for contamination also, as transmission fluid also runs on the outer region of your radiator to cool the transmission fluid.

How can you tell from motor oil to transmission oil leaking in the radiator?

there's no way gearbox oil/transmission oil can get in the radiator... only the engine oil can. this usually will happen if the cylinder head is cracked or the cylinder head gasket has failed. However, Transmission fluid can get into your coolant, by means of a corroded internal transmission cooling line, which is inside the radiator of many model automobiles and trucks... it will look somewhat like pepto bismol at the cap..

What would cause water to be in the transmission of 98 Chevy pickup?

I can't see any reason for water to get in the transmission unless it went under water from a flood or crossing a stream. If engine coolant is getting into the transmission I would blame the transmission oil cooler in the radiator in which case the radiator would need replacement and the transmission flushed professionally. If the vehicle was driven with coolant mixed in with the transmission fluid you will probably have transmission failure before long.

What do the hoses hook to in the transmission?

Your transmission pan isn't large enough to cool the transmission fluid like the oil pan, so there is a transmission cooler that looks like a miniture radiator that is typically located in front of the radiator.

Why is antifreeze blowing out from the radiator cap of a Nissan Titan?

If it's just blowing out when you start it you probably have a cracked head or blown head gasket. If there is oil in the radiator there is a change you have oil coming in from the transmission cooler. But there would have to be a lot of oil to make antifreeze come out the radiator cam. Since you did not mention oil I would suspect the head gasket. If you got it hot I would lean toward a cracked head.

2000 Pontiac grand prix and the transmission oil is milky in color and the oil level continues to increased and the transmission slips?

The reason the fluid is a milky color is that water is getting into the transmission. How you ask??? Well the cooling lines go into the radiator to cool the fluid. It is at that spot it is picking up water as the cooler inside the radiator has a leak. the best solution would be to change the radiator. You could block the fitting ports for the lines at the radiator and put an external cooler on it. YOU MUST thoroughly flush the transmission and change the fluid and filter.
