Though about using my old AC condenser as an Auto Tranny cooler, my tranny gets really hot, and just last wheeln trip, blew its rubber ATFF keeper, the keeper melted from the atf getting sooo hot, anyway, i would use my AC RADIATOR add about 1/2qt more atf to accomidate for the large radiator, just wondered what yall thought...

I have a small 10" x 7" radiator for the tranny now.

thanx!

Hey Smart ASS I have NEVER heard of a AC radiator. Perhaps your thinking of the A/C condenser???:flipoff2: :flipoff2:



Some people have had problems with clutch slippage due to a pressure drop. The volume of the condenser is just to big for the trans pump to handle. Why not just do it right and get a real cooler for $40-50

i second that. you would not catch me risking smoking a tranny trying to save 50 bucks.

YES....one of the best $50 I ever spent ! Cheep an easy !:D ;) :p :) :flipoff2:

:jeep: __(OIIIIIO)__rOkOn:usa:

YO JACK ASS, IF YOU COULD READ YOU WOULD KNOW THAT I ALREADY HAVE AN AUTO TRANNY COOLER!

SO ATLEAST I DONT TRY AND SELL PEOPLE A FORD EXPLODER, TELL THEM THAT IT WORKS, AND THEY DRIVE 1000MILES TO SEE IT, AND ITS FWAKED, YOU SNAPPED THE TRANSMISSION IN 1/2, THE DAMED A4LD CASE WAS CRACKED, SO KISS MY ASSSSS !!! :)

Volume and pressure are two different things.

If you have a one inch tube feeding a three inch
tube then yes the volume of the three inch will
eat up the one inch volume.....only if it continues to be three inches. However if the three inch turns back into a one inch then
the output volume will remain the same.
The only difference will be the time factor that
it takes to fill the three inch area. Once the
large area is filled then the input will be the
same as the ouput in regards to volume and pressure. The key is to make sure the ac condenser has both inputs and outputs at the same level...which most ac condensers have. Next you
have to make sure which kind of condenser you are using.....the old tube type or the newer wafer
type. I've been using a 2x3' former ac condenser for years now with no drop in pressure or clutch
slippage. Solved all my auto trans over heating problems with is what kills the auto trans in the first place. My tranny runs 180 all day long
with the ambient temp as high as 110 degrees during rockcrawling. I can make it run hotter
during the winter if I like just by putting a
cardboard piece in front of the cooler.

All they are is heat exchangers whether they
be water/engine oil/trans oil/heater cores.

I like that idea. Too bad I still like my AC, it still works. I'll probably switch it to a air compressor when it dies, and I'll keep the ac condenser in mind. I plan on putting a trans temp guage in soon due to the fact of that I have an auto tranny. Also I plan on welding fins onto my pan. I was going to buy one of those expensive pans but technically I could build it myself.

Cut out a square out of the bottom, weld in 1"walls for the extra capacity and weld on the fins.

Does anyone know where to get a dropped pickup for the 4L60E which pretty much the same as a 700R4?

:usa: SWEEET Man, finally their is real people! I was thinking teh same thing... why would the fluid be working harder? same size/diameter tubing. just more distance to travel, and its FLUID, not very much resistance. The only difference would be that i would have to add .75 mor of a QT of ATF to accomidate or the larger cooler.
I plan on seting it up under my flat bed some where with an elextric fan. (under bed mount idea by: RockRanger)

Hey THANX MAN! :beer:

I'v seen it done before, the ac condenser may not be too bad as its design allows for minimum pressure drop. I do agree though you are better off buying an aftermarket cooler. get the biggest you can find and run it before the stock cooler, the reason I do it that way is to stabilize the temps, up here it gots cold and really cold tranny fluid can be just as bad as really hot.

huh?

this is one of those situations where what you want to do will probably work, but.....
it's one of those situations where you could use your condensor but using the right equipment would probably work best and be more reliable. A small cooler with its own fan would work really well.

actually you should check my other post,

IT WORKS!

It workd better thhan anything else, and i lose the small ass tranny cooler and gain a cool happy tranny.

Example, the heat going into te cooler, i cant barely touch the metail line to the cooler, almost too hot to the touch, the outgoing line from the cooler is WARM, nice warm operational temp for my AUTO :):flipoff2: :rasta:

<FONT COLOR="Red"> I think your tranny will just love having that fat assed cooler hooked up to it..:d The potential problem that I see is that it could possibly dump too much heat. If it's mounted in front of the radiator, the air that hits the radiator will be hotter and might cause summertime overheating.

Its cool, actually the EX-AC COOLER/CONDESOR (now my C5 Cooler) was stock in front of the radiator. + I also got a full wrap arround shroud for the clutch fan. But yeah, i hear ya, its more or less a test, ya know, "live and learn"

OH....Did I forget to mention that I have the
ac/tranny cooler mounted underneath the bed
of my ScoutII. It also has a thermostatically
controlled fan that is inline with the oil
return line. The reason that I put it in the
return (read output) of the cooler is because
that way I can ensure that the oil is being
cooled to the proper temp as it enters the
transmission. If you put it on the other end
(input) then you might be cooling it too much
before you use the cooling ablity of the cooler.
Now here is the really neat thing. I also have
a valve that senses the trans temp inline
with the input to the cooler. This valve senses
the exiting trans temp and will close if it
gets below the proper operating temp. Now I know
you're wondering if it closes then where does the
oil go to....heh..heh...well it has another output
that goes (with line) to the ouput line of the
cooler. Now you effectively bypass the cooler
in cold weather climates. Pretty trick eh?
Being an ex-motorcycle roadracer cooling is very
important to lasting an entire race.
One more thing....I see you are using a round tube
cooler. Very inefficient. What happens is as the
oil circulates through the tube only the outer part gets cooled. Going right through the center
of the tube is still hot oil. This is because as the oil cools its viscosity changes to become thicker thereby isolating the inner flow of oil
which stays hot. Get a wafer design cooler and
you'll cool the same with half or less of the size/area. Plus the wafer design flattens out the oil
and gives a better cooling surface.
Hope this helps.
