You don't need to.

Agreed.  Besides, there is no oil pump inside a manual trans to move the grease through a cooler.

If you ran a light fluid like auto transmission fluid in the case you could run an electric fuel pump to move fluid from the tranny to a cooler and back. You would have to tap the case for a send and return. I would think you would tap the case underneath for the send and return near the top.

You would make the pump run on a keyed switch.

You would also need an inline filter in that situation.

Although not exactly the same, I run auto fluid in all of my mower racing 5 speed transmissions and in my 1973 Wheelhorse tractor. Everything comes out super clean on every change.

If you really really really want some cooling, and you are right in your thinking. . . .
 
I suggest attaching some heat sync to the case.  You can get it in many different shapes and sizes.

RATHER THAN TAPPING THE CASE, COULD I RUN IT THROUGH THE DRAIN AND FILL HOLES? I THINK IT WOULD BE EASIER.

Manual transmissions don't need this whatsoever, it is mostly a waste of energy to do it, it is simply a gearbox that uses gears with oil that splashes around in it. Automatics have them because the fluid is under pressure, which adds to the heating of the fluid. Now newer manual transmissions use lighter oil because the clearances are so much tighter than the older transmissins, which used heavier oil, but all in all, talk about a waste of time and energy.  It would then be easier to use the PTO takeoff and oil pump to pump the oil vice a fuel pump, because too light an oil would cause more damage in the transmission than running a pump to cool the oil itself.
 
In short, keep the fluid volume where it belongs and don't worry about the small amount of heat it produces.

Show me ONE Class 8 truck with one and only then would I rethink my position.

They turn at much lower RPM than a street car. They only run 1600 rpm down the highway versus 2000 plus of a street car.

RPM equals heat.

Plus some newer cars with manuals come equipped with tranny coolers.. maybe the engineers in the auto makers are wasting their time I guess..

Yes, they turn at lower RPM, but they pull up to 100,000 pounds.  They work a Hell of a lot more than any car transmisison.


 
I think we're going in circles here.
 
It's obvious that some of us think it's unneccesary and others are of a different mind.  Bottom line, it's your vehicle; do with it what you want.

apology for this up. I'm
looking for an aux filter solution for the transmission, so I won't have
 to drop the pan and replace the factory filter. my car did away
with the drain plug on these transmissions and I'm done with balancing
piping hot trans pan on my hand, while removing 16 or so bolts. Fluid
replacement will be done via disconnected hose from the factory cooler.
So
 basically I need a filter solution that will do all the filtering from
now on and is easily accessible/ replaceable. Price is somewhat of a
concern, but it has to be a high quality setup. I'm just a little worried about
the pressure drop with all these add-ons (automatic transmission filter (http://www.racepages.com/parts/automatic_transmission_filter.html) and transmission cooler).(http://www.moparfins.com/forum/smileys/smiley1.gif)

I just bought one from Fastco.com for 16 bucks.  I get it tomorrow
