Transmission Fluid can be sucked into your oil if the modulator valve fails on the transmission. A modulator valve is mounted on the side of a transmission and is hooked to a vacuum line that is connected to the engine. If the diaphragm in the valve ruptures then you end up sucking transmission fluid via the vacuum line into the engine. If not repaired promptly you can very easily double the volume of "oil" in your engine as the transmission fluid mixes with the oil. A simple test is to disconnect the vacuum line that runs down to your transmission and if it is filled with trans fluid the diaphragm in the valve has ruptured. A modulator runs less than $20 and takes about ten minutes to replace (if you can get at it). On some vehicles there is an access plate cut into the transmission hump (under the carpeting) that allows you to access it from within the interior of the vehicle. 1994 Mazda B3000 for example.

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.

How is primary fluid different from motor oil?
If your using Syn 3 oil nothing. The big difference between standard motor oil and primary/trans fluid is the lack of sulfur in the motor oil and the viscosity, the sulfur helps adsorb shock and is much better for the trans. A far as the primary goes the thinner oil is much better for your clutch, ATF is also a good primary fluid, many companies like Barnette recommend it.
