the trans fluid on a auto trans goes through a tube in the radiator to cool the fluid if the tube has holes in it, it will leak trans fluid in to radiator. you need to replace radiator or have rebuilt.or you could put on a aux trans cooler and put plugs where the trans lines used to go.


Is it normal for water to be coming out of a leak in the cooling lines to the trans in a Lincoln town car?

no,their must be a leak inside your radiator where the trans lines are screwed in. The water in the radiator is to help keep trans fluid that passes thru radiator cool. should have no water coming out of trans lines.

Will the radiator over flow make the transmission go up?

If you mean does the transmission fluid level rise, the usual problem is a leak in the trans cooler built in to the radiator. Depending on engine temperature fluid will transfer back and forth between the radiator fluid and the auto trans fluid changing the level and color of both.

How does trans fluid get into radiator?

You will notice two lines going to your radiator from the transmission. One is a service line and one is a return line. The radiator has a transmission cooler built into it. If you have trans fluid in the radiator chances are the trans cooler is leaking. A little trans fluid in the radiator will not affect engine cooling BUT as soon as the pressure drops in that transmission you may very well have radiator coolant sucked into the tranmission and that will ruin a transmission in a hurry. You need to get this checked out as soon as possible.


What will happen when radiator has a crack?

If it is a water-filled or oil-filled radiator, it will leak fluid.


The radiator has transmission fluid inside which should you change first the transmission fluid or the radiator fluid on your 97 ford explorer and also what is the torque spec and sequence.?

You need a new radiator if you have trans fluid in the radiator. Getting trans fluid in the radiator isn't such a big deal...just change the radiator.....the worrisome parts is getting coolant in the transmission. The radiator has a transmission cooler built in and it is separated with a wall of aluminum - the coolant and trans sides should never mix. First! You need to drain and remove the radiator and replace it with new fluid. If you got trans fluid in the radiator, it very likely means you got the inverse....coolant in the transmission. You also need to flush and drain the transmission. Also, you need to flush the transmission cooler lines out for any coolant. Coolant in the trans is often the death of a transmission. Make sure you use the right fluid in the trans. That vehicle takes Mercon V fluid - don't put anything else in there or you will have problems potentially.


What causes oil to get inside the coolant?

A leaking head gasket is is most likely cause, could also be cracked head or cracked block. A leak in the trans cooler which is located in the radiator would allow trans fluid into cooling system.


What causes transmission fluid to leak into radiator?

Cracked radiator end caps since the tranny fluid runs goes threw the caps for cooling that is the only way tranny fluid can get in the radiator
