Transmission Cooler/Cooler lines

-
Put two on mine, stacked plate design, had them directly mounted on the radiator when the car was a 6 cylinder and they worked well, now i have spaced them off the radiator, not sure if they will work any different or keep cool air from the radiator. I used 1/8 npt to 6an fittings and bent up some 3/8 hard line from trans to rad to coolers and back.

That looks great!
Any chance you could take a closer up pic of the mounts and the lines heading to the rear?
That’s about exactly what I’m planning.
Thank you very much!
 
My car is a street/strip car that never goes on the street.
I run my cooler lines through the radiator, the through the aftermarket cooler in front of my radiator. then back to the transmission.
Been doing this way for two many years to count.
If it was a full race deal, i would by-pass the radiator and just run the aftermarket cooler.
 
I try not to run the cooler in the radiator, I understand about heat management, but a friend of mine had the radiator cooler go bad. So the atf and antifreeze mixed. I have run the Moroso stick on heat pads on the trans pan before. I run the large plate cooler on everything I can. They make 1/2 pipe to # 6 an fittings, and 1/8 pipe to # 6 an fittings.
Many many years ago I had a friend who's daily driver trans went bad requiring a rebuild. All the friction materials came off the clutches and bands.
The new rebuilt trans lasted a week and failed the same way again.
It was found that the rad was bad allowing a small amount of antifreeze into the trans fluid. There is a chemical reaction between
Antifreeze and the bonding glue on friction materials that dissolves the glue.
 
I run a Derale cooler/fan combo in front of my fuel cell, just behind the rear axle. Bought new on ebay for $40 (they're about $130 normally). At the trans I found NPT to -6 adapters on Summit, and ran ATF rated line to the cooler. Wired the fan to kick on at same time as rad fan. Keeps my 9.5" converter cool!

I did the same thing on my dart. Outback helps with weight distribution.

For the cooler mounting i used what i had on hand it's about 1/2" square thin wall tube, I used nutserts into the tube to secure both coolers and to body, cooler lines are 3/8 nickel copper and a bit of rubber line at the coolers to allow for movement, the hardline passes through the radiator support via speedflow Bulkhead fittings then all hardline from rad back to trans.

I have a Derale/with fan unit. It is mounted under the (driver side) passenger floor. The lines go straight to the cooler. Nothing to the rad.. You don't want your trans. fluid running the same temp as your hot rad. after a run.
 
With my new 4200 stall converter my cooler had been getting might hot when i hot lap it. It may be time to by pass the radiator.
My theory with it was that the oil come out of the converter at 200+ degrees. running through a radiator that is 160-180 degrees would be like a smaller cooler to take to top off of the heat then send it to the air to air cooler.

I'm still going to have to think on this for a minute more................................
 
So.......In my minds eye, the biggest problem is that you need to keep the eng running in N to keep the fluid circulating to cool the transmission(which no racer wants to do).

just spit balling here.
So in my mind the best solution would be a thermostatic controlled fan/cooler set up. But this does no good unless the eng is running............
So now i think, hmm what about about a pump? I could circulate the fluid and cool it down quick.........but the last thing you need is a restriction in your cooler line(external oil pump) maybe a check valve and then a by pass that run to the pump. when the pump is running it close the check valve and circulates the fluid.
any one know of a pump like this that could withstand 300+ degree oil and what? 150 psi of pressure????

The greater the DeltaP the greater the cooling. Take the radiator cooler out of the system.
 
Some thing like this. pardon my penmanship. It tough when you pen is a mouse.
Sorry that came out a little smaller then i intended it too.

Now that i have taken the time to draw this up i realize it won't work!:BangHead:
You would have to build some kind of by pass around the pump in the transmission(you won't pull much volume around a non moving gear pump):BangHead:
o well will still post it up for giggles:p
 
To quote Rick at A&A transmissions: "there's no such thing as a trans cooler that is too big.." It increases overall capacity of the system to boot. People at car shows ask me where the rest of my AC system is :lol:

Expensive but you want something like this.

I couldn't find a price on it but, what a clean way of doing it. my picture show hacking in to the line in 2 different place to get the job done. That shuttle valve make it simple. Basic relay wiring.

Really want to do this, but i would only do it if i had a remote cooler and fan. Which adds a hole bunch of Dollars $$$ to the project.
It's on my "to do list" but it a long ways down the list.
Thanks for the link:thumbsup:

Yes I would like to do it too. Already have the cooler mounted out back. Just not ready to pull the trigger on that pump yet.
But yes his custom valve sure simplifies things and it gets the hot oil right out of the converter as well.

$599.00 shipped. Not cheap. There are cheaper pumps out there but Jones has a nice check valve assembly.

How about you run the trans. lines forward to a large cooler in front of the rad.. Then use the pump you drew and tap those two lines into the trans oil pan. With a rad, and fan this gives you an independent system from the other. And you can run it even when the car is not. My 2 cents
 
Im not sure i'm fallowing.
Something like this.

This is the routing of the Jones racing pump.
The beauty of his system is it cools directly into the torque converter
and uses the same cooler and fan already on the car. I believe the block relies on check valves and gravity to automatically correctly choose the correct flow route depending on whether the engine is running, or if not, and the electric pump is on.
Most popular transmissions route the cooling directly out from the converter to the cooler. The Jones routing flows in reverse so that the hot oil out is now cool oil in directly to the converter. When the electric pump is turned off, and the engine is restarted, the flow goes in the normal route and the check ball in the block routes the proper flow direction of the oil. Simple but ingenious.

Never gets the hot oil out of the converter.
 
The way i read that diagram was that the oil pump was pulling oil out of the OIL pan and rotating it threw the cooler and then dump it into the inlet.

I don't think that the add-on oil pump is pushing oil back through the converter backwards.
The reason i say that is, that if it was pushing fluid backwards through the converter........then it would be pushing it through the transmissions oil pump, right. and its a gear pump or a positive pressure pump. won't push it through that pump with any volume at all.
I think its pulling it from the pan and running it through the cooler and dumping it back in to the transmission on the return line.
I could be wrong but thats the way i see it.
