Transmission cooler in radiator? needed?

I got this idea from Chad(casfz1) about running 2 stock tranny coolers in series, thought it was a decent idea since the tranny runs so hot.

But my theory on why it runs so hot is that it runs though the radiator that has 1** and some odd temperature coolant running though it so if anything its heating it up warmer! If I cruise down the highway at a constant speed when the radiator gets good air flow the tranny runs at 150* but when im in town driving around and the efan has not kicked on yet the water temp goes up and so does the tranny to 180*+ Once the tranny is running at 180*+ is shift like crap and I'm sure its not good on it.

So anyone know why it is ran into the radiator? Whats the purpose? Is it needed?

I had heard that part of it was to warm the fluid for cold weather operation since auto trannies don't like to run when the fluid is extremely cold either.

dont think it will heat up enough on its own? I'm thinking it will unless its like 10* or colder out...

They run it in the radiator like that for ease of install. If you really want to take care of your trans. Do what I did on my old truck, run a 25,000LB GVW trans cooler. I towed my boat with it up and down hills and on 5 hour plus trips with no problems for 160,000 miles. Its was worth every penny.....

i added a B&M tranny cooler to mine....i need to find out if i have it on the output line in the radiator or if it goes through the cooler 1st then to the radiator........i have been thinking about adding a second cooler to it for extra cooling......during the summer with the cooler mine gets up to around 180* (granted i take temp readings from the line by the radiator right now)....

my brother is running only an external cooler on his 500HP '79 F-150 with a C-6.....granted it is 1.5" thick and 11"x20"......

Zack,

I would go that route, as I said with my old truck, it worked wonders for the trans...

Thats a good idea, I should probably get an engine oil cooler with all the towing I do....

Hell yeah, thats a good deal for sure. I just wonder what kind of cooler I need, since I only need it for engine oil. (manual trans)

you could get this oil cooler:

but for the price of that dual cooler, i would get it and just loop the oil back into the other side of it and then back to the engine.......

with any aftermarket cooler, you get about 1/2 to 1 quart more fluid in whatever you are cooling also......

idk i think an oil cooler is over kill, its not really needed. if you change your oil when you are suppose to there should be no problems.

i used to tow a lot, so far i have yet to see too many people tow with their ranger more then i did.

I added a large aftermarket cooler to my truck this past summer. If I remember, it measures out to something like 11"x11"x3/4". It makes a huge difference in temperature just by feeling those steel lines running under the radiator. When I tow, the line coming from the trans is so hot, I can't hold my hand on it for long. The other line coming from the coolers is almost air temp.

This is the way mine is hooked up:
Trans --> Radiator --> Factory Aux. Cooler --> Aftermarket Cooler --> Trans

I got this cooler at Napa. Supposedly, the "stacked plate" style coolers are more efficient than the rugular tube-and-fin style coolers.

Here's a pic of my wife helping me install the cooler.

It couldn't hurt, I tow 5500 pounds allot. Maybe I will reconsider, IDK.

which line did you put it in, the line that goes into the top of the radiator or the bottom line?

why not something like this?

http://cgi.ebay.com/ebaymotors/DERAL...pagenameZWD10V

i mean, can you upgrade to a bigger trans cooler with a fan, and just replace the stock on all together?

i don't think there is enough room in front of the radiator to put one with a fan........the fan would only be helpful when you were in stop and go traffic......

if you eliminate the stock 1 all together, then you need a LARGE cooler to do the job of the stocker and an aftermarket......

When the transmission is cold it will not flow fluid in to the cooler. As it has a thermostat just like the engine.


I cant see the radiator providing much cooling. Add an after market cooler and a temp gauge. If you really like over kill and total control, get one with a fan you can turn on.

the one seminary ranger showed- thats the same size the tranny guy put on my s-10. he bypassed the radiator completely and this unit handles all the coolong. It's mounted to the front of the radiator (no a/c condensore on this truck). The e-fan pulls plenty of air through both it and the radiator. I can put my hand on it and feel the air getting sucked in. Being on the outside, it's getting cool freash air. Not air heated by the radiator.

I ripped the factory oil cooler lines off the s-10. Thats how I feel about them. Just another potential leak down the road.

I can't remember the part number, but I do remember that it was a Hayden brand. I paid about $40 for it.

The reason I got it was because it was able to just bearly squeeze between the A/C condensor and the metal support that runs behind the grill.

I do a lot of slow speed driving checking cattle pastures, I tow occasionally, and of course some mud here and there. The cooler provides some nice peace of mind.
