How Much will this Hayden Transmission Cooler Cool

The Ls Swap Radiator has a Transmission cooler but it wasn't doing it job, I purchased myself a Hayden transmission cooler to piggy back to the Radiator to help lower my Temps just a bit. So far doing this Mod has kept my Ls Swapped Jeep wrangler TJ nice and cool

I installed a bypass trans cooler on my Escalade because I live in Arizona and would operate 20 degrees higher than normal operating temperature. Now that it’s bypassed, it runs at the correct temperature even in the 110 degree summers.

I don't care how big your cooler is...your transmission will never run too cold. Oh, if it's 30 below zero, when you first start the vehicle...sure it will run too cold for a few minutes....but, not for long

No need to bypass in the winter. Minnesota here, 210k+ on my trans and I got a big 11 x 11 hayden cooler, bypassed the rad for the last 7 years, never a problem.

Thank you. Straight documented results. No flawed theory or BS discussion - just before/after comparison. Well done.
That said, many modern systems run with a small 'thermostat' that must be bypassed, like in my Crown Vic. Thermostat bypasses the cooler until it reaches 180 degrees or so. There are kits to eliminate the thermostat, which I have done AND added an additional cooler. Other systems utilize engine coolant in a heat exchange unit such as in my Jaguar XK. In that case I replaced the factory cooler with a heavy duty unit and eliminated the transmission coolant loop from the engine cooling system. Now they're completely independent and have fewer failure points overall - like a normal, old fashioned car.

Mate you need the hot entering from the bottom and cold out the top of factory transmission cooler to stop air bubbles.

The drop in temperature with the cooler installed was mainly caused by colder air hitting it at 60mph. The fan on that cooler isn’t going to be of much help. The large hub of the fan covers most of the surface area of that cooler; barely any blade coverage. A fan with a much smaller hub would be better. Ever stand directly under a ceiling fan and notice that when you step to the side a little, you get more air blown on you? Plus the two bars also impede what flow that fan will provide.

60° is huge drop in the temp.
Might have to bypass it in the winter.
But time will tell.

Beautiful seeing those temps drop. I have the same radiator, engine/trans, in my 06 TJ and my transmission temps are a lot more than I'd like them to be and it's not even hot out. Might have to give this cooler a try.

[Daniel-tvtb]

That is incredible. I will do this to my JKU once my fsctory warranty expires!

[edsecce]

60 degrees cooler without running the fan? I guess you can skip the fan and still get great results

[mmmaaa]

Thank you so much.
I was wondering if the fan add value or not?
Have you ever used it.

[dragan]

I was told for performance to get biggest cooler!

[kdunc]

I am sold and impressed with the numbers.

[payloadperformance]

What type of electric radiator fan do you have to cool your engine?

[avishekchand]

Not sure where you are located but they have koyo radiator for automatic transmission thats a bolt on. you can see on nightrun garage for reference.

[brucek.hoffman]

was just thinking about installing a cooler on my future daughter-in-law's '15 civic because it has a CVT, & u do know they r not good wen u hav 80k... i also use & sell AMSOIL, so between the 2 i believe it will add long life 2 that trans... can't believe the drop in temp... liked the vid, good job my friend...

[foxmulder]

I just got one, I want to just wire it/tie it to my sway bar on my XJ right under by the front bumper...lol cause I don't want to take the grill I just installed off and it seems like it would work better getting better air flow down there, and wouldn't block my radiator? Is that a bad idea? Lol

[whatfreedom]

I need one for my Tacoma. I’m towing a 21ft camper up steep inclines at low speeds. So there isn’t a lot of airflow. I have a mechanical fan and no way of knowing what my temps are. Id at least like to add a 11x9 since the stock is only 4 1/2” tall and it’s blocked behind the large grill area so no airflow is even hitting it. Idk if I need a fan or not I just need something cheap to get me by since I plan on dumping the truck and getting a full size truck.

[kflippen]

Where did you get your fittings to piggy back that cooler? I have s10 with a 4.3 factory cooler is not enough and need to do the same

[Chriselectricfingers]

If your TC has a thermostat in the condenser u should in line new cooler after ur condenser, that way no matter what ambient temps are, the TC will always keep the warmed up oil temps to operate correctly which in return the new cooler will keep ut from not going too high, ,,
