Hayden Trans Coolers
« on: Jun 10, 2012, 05:09 PM »
Has anyone heard if Hayden tranny coolers are any good. I'm wondering because I bought one and the temp rises slowly but I think its not working all that well. Someone have any info would be most appreciated.

What is the temp rising to?  Keep in mind we're coming out of the winter months so temps are going to be a bit higher.

What are the specs on your cooler? Also, how do you have it connected, meaning are you using it inline with the radiator or bypassing it?

Jegs sells the Hayden ones as "there own" brand.  I have one on my GXP inline with the rad cooler and it rarely goes over 190 even when its really hot here.  The only exception would be a traffic jam where I have seen 200 still, but it was very hot that day.  Would have been 230 with the stock setup.


I also have a Hayden on my F-250, but I don't have a temp monitor so I couldn't tell you what it runs....

My GXP would top out at 204 degrees if I'm not running the car hard. My cooler is pretty big, so I don't if its too much for the tranny.

It actually will work better if you eliminate the radiator from the path. Reason being is that the radiator is being heated up by engine coolant, so the trans fluid will also heat up to that level.  So if you put the cooler after the radiator, in line, it heats up and then cools a bit before hitting the trans. I think you would get better results with a larger, stand alone cooler.

His cooler should be fine for a stand alone setup.  It's rated at 26,000gvw.

Ok! I will do that this weekend, now for pluging the radiator, what kind of plug should I get or can I go to a hardware store and buy brass plugs that won't damage the radiator?

It's not necessary to plug the radiator.  Nothing is running through the trans cooling circuit once you've bypassed it, so there's no worries on leakage.

If it gets cold where you live i always reccomend leaving the rad portion in the circuit , the heat from your engine will help bring the trans up to temp when its -40 out.
With no aux cooler when it was -45 here the car ran for 45 minutes and was only up to plus 25....

If it's a stacked-plate cooler, then this is not a concern, as it will bypass itself until the fluid gets warm enough.  Interesting thing, fluid dynamics!

If it's a tube-and-fin design, then you're absolutely right.  If you routinely see sub-freezing temperatures for long periods and you drive short distances so that the trans can't warm up, you should probably leave the radiator cooler intact.
