Well, many cars have a trany fluid cooling radiator as part of the overall radiator. In other words, lines go into and out of a radiator, carrying tranny fluid. There is a small, separate radiator for the tranny fluid inside the radiator.
 
If there is a leak into this tranny radiator, you've got big problems. Pull the tranny dipstick, and see if the tranny fluid looks ok. It should be red, usually. If there is any foam, or looks like water bubbles on the stick, the coolant if probably leaking into the tranny coolant.

The cooling fans of my 1996 Plymouth Grand Voyager SE won't come on, which is the cause of my car's overheating, even after I have replaced the fan relay, thermostat and coolant temperature sensor. What could be the real problem?

Not my car of choice but it has to do so I can get to work. Just had it towed home tonight, missing the Super Bowl, darn. It took me 3 1/2 hours longer to get home from the lake then normal as I had to stop 4 times to let the car cool down. Before it would be that I lost most of the antifreeze and after cooling and adding antifreeze, I was back up & running. But tonight it would overheat but did not loose any antifreeze. Once cooled, I made it maybe 3-4 miles before having to pull over again to cool. Temp gauge went beyond H and heater started blowing cold air. I was told the upper radiator hose has a leak but it seems to be more problems than that now. I have never replaced the radiator, flushed, thermostat or any hoses. I am a single lady with a small income and do not have a man/mechanic friend to help me out. I am very competent and would attempt to do any repair that is fairly easy. I have built houses, poured concrete, laid landscaping bricks and the like. Oh I also caught a 8 1/2 lb walleye! I am willing to try something new and if it does not work out, at least I can say I gave it my best shot. Any suggestions would be appreciated.

Possibly a blown head gasket. Major fix required for this. Maybe the motor is already ruined from all the overheating. You need a good mechanic to diagnoise this.

My 92 voyager overheats after aprox 1/2 hour idling. Oil looks clean. Radiator water looks pretty clean. Can you tell anything from the graph or suggest further tests? Below are a graph of radiator inlet temp and radiator outlet temp vs time; and the data; the radiator boils over into the overflow container at the end of the test. Thanks

Does the fan or fans come on at any point during the 1/2 hour?

Is there a thermostat in it? Or stuck open? This is not the graph for the top hose temperature (at radiator? or at thermostat end?) that I would have expected. I would expect it to stay fairly cool for 5 minutes or more as the thermostat holds back the flow, with only minimal heated water volume getting past it into the upper hose.
 
Then I'd expect the lower hose temp to stay cool until after the thermostat has started opening and higher volume of warm water flows into the top but is mostly cooled by the time the water reaches the bottom. Then I'd expect the lower hose temp to start up.
 
Does the heater inside produce good heat after 3-5 minutes?
