There IS A THEORY that heat rises,,, The fluid,, in theory,, SHOULD go into the top and,, as it cools,,, travel through the cooler and EXIT THE BOTTOM and return to the transmission... If you put it the other way,,,, the fluid won't get as cool,, because EVERYONE KNOWS that HEAT RISES ???? Make sense????

Actually everyone THINKS heat rises when in fact hot AIR rises and heat goes where it's pointed.
You usually want to pump fluid into a cooler from the "bottom" and return from the "top" so that no air can get trapped in the cooler and reduce it's efficiency. An example of this is if you hook up the heater hoses backwards on a heater core you will get a lot less heat in the car than if they are connected properly.

So which of the outlets on the transmission is the outlet and the inlet so to speak?
Front is outlet and rear is inlet, as far as the cooler, it really dont matter which you use as inlet/outlet, mine is long and narrow sitting in front of the radiator, the heat rises therory is correct but with most addon trans coolers that dont go thru the rad cooler first it makes absolutly no difference in cooling effect. 
Light travels faster than the speed of sound,,,this is why some people seem bright untill you hear them speak.

OH BOY.. If you take an infrared temp gun and point it at the top of the cooler ,, it will be HOTTER than the bottom of the cooler regardless of WHERE the cooler lines are connected.... Another thing about putting the fluid IN the bottom and pulling it from the top,,,,,, WHO CARES if there is AIR anywhere,, it will be PUSHED OUT BY THE FLUID in a second or two... the bubbles couldn.t move faster than the flow of the trans fluid,, through the fluid... it will PUSH all of the air out of it.... IN the top and OUT the bottom... Hot on top and COOLER on the bottom.. KINDA LIKE the SAME WAY A RADIATOR WORKS....

Unless you got a electric fan cooling that cooler down,, HEAT RISES.... Initially the input will be hotter than the output,, but,, after it heats up,,, well/..../....

Now that is hilarious right there... so you're saying that the hot trans fluid coming into the cooler will actually get hotter before it exits if you plumb it upside down?!
In your "theory" that is the only way for the top (outlet) of the trans cooler to be hotter then the bottom (inlet)
That is one of the best ones I've heard in a while...

I NEVER said the fluid will get hotter,,,,, I MEANT that you will not get the FULL EFFECT or the FULL AMOUNT OF COOLING if you TAKE the fluid from the top.. HEAT RISES and the heat dissapated from the bottom of the cooler will Rise!!!! Will some of it heat up the top of the cooler,,, YES,, will the fluid be cooler if you remove it from the BOTTOM of the cooler than the top of the cooler??? YES.... WHY DO YOU THINK when there is a RADIATOR with a TRANS COOLER in there,, the fluid GOES IN THE TOP and comes out the bottom... DETROIT has DUMMIES for engineers???? COME ON GUYS .....

Maybe I had to re read that one.. If you take the inlet temp and the outlet temp,, naturally the fluid will be cooler from the outlet.. That's the whole idea of a cooler.... If you put the heated oil in the top and remove it from the bottom,, the overall temperature difference will be GREATER than if you inlet the bottom and outlet the top.. Some of the heat will be absorbed back into the top of the cooler because of the theory of HEAT RISES.....THUS limiting or stifling the function of the cooler...

HERE YOU GO.. You're SIXTEEN years old,, you check your trans fluid and you're a little bit down... You do to the parts store, or local gas station and get a QUART of TRANS FLUID.. You get and old funnel OR use a piece of notebook paper and proceed to DUMP THE WHOLE QUART into the trans dipstick tube... Needless to say,, you just dumped WAY TOO MUCH OIL into the trans and now you have to get it BACK OUT... You go to the PARTS STORE and get either a piece of 5/16 OR 3/8 FUEL LINE and you proceed to take one of the COOLER LINES off of the RADIATOR to remove the fluid... WHICH ONE DO YOU TAKE OFF?????? THE TOP ONE,, because the trans fluid comes from the trans and GOES INTO THE TOP of the cooler.... You slip the hose over the trans line,, your buddie starts the car for 15 seconds and you pump the whole quart BACK INTO THE QUART CAN !!!!!.. DOES that BRING BACK MEMORIES??????

Be that as it may, if you had paid attention in high school you would know that heat does not rise. Common misconception because hot air rises and most people's exposure to heat involves a furnace and a cold house.
Ever notice where they install industrial radiant gas heaters? Mostly on the ceiling pointed down. If your theory was true they wouldn't work very well.
