The way the factory Transmission cooler system works is... The Hot fluid from the trans (front fitting on the trans) runs to the cooler first... It goes out of the cooler then runs into the top port of the Radiator... It goes out the bottom of the Radiator (where it is now cooled) and to the rear port of the Transmission. The Idea of it running through the cooler to the radiator is to "normalize" the fluid temps on both the coolant and the radiator. Lets put it this way... if you get stuck in traffic on a hot day and you just have the Front mounted cooler... you have only the airflow from you fans that have to make it through the radiator and ac condenser... your trans temps will climb. If you run it through the radiator after the cooler now you have the radiator doing the work. I have done it both ways with my Suburban 2500 towing a 6k trailer daily and having both the radiator and the cooler work the best in all situations. I would keep it running through the radiator.

The cooler is supposed to go after the radiator cooler/heater. You need to connect it in line because you want the trans fluid to warm up and flow better in really cold weather and you want to return the coolest fluid back to the trans from your new bigger cooler.

I bought the same cooler for my 1988 Ford F250 diesel pickup. My truck has the C6 Ford transmission, those transmissions are a lot less prone to overheat and failure than the new 4L60E, but I figure it's cheap insurance so it makes sense. You can also run it in tandem with the factory cooler in the radiator which is what I did. They can be used on a bunch of applications. And, it is just that easy to install.

I would reccomend a trans remote filter too. I have mine located under the air filter housing

I was recommended to get this cooler for my tahoe the other day and seeing how easy the install is Im going to be doing it soon

A Mexican friend once told me that a crescent wrench was a Mexican socket set.

Great video! Very through, I'm installing mine this weekend. This video should make it a breeze. Thanks for posting

since you deleted the line how do u cover the hole that open on the radiator or do u just leave it be

Supply goes to the top, and return is the bottom. They designed it that way because heat rises. I believe there is an ANSI code for that?

Thanks for the Video My dude!! I have already ordered mine for my 07 silverado. Looking forward to installing. Thank you fro the video!!

Orale!! Mexicanada!!! I see foolios paying 50 to 80 bucks for bracket kits to mount that same cooler!

this was so helpful thank you 😎💕

That's kinda a rare truck. rcsb z71 I want one

Think the right way would be with the inlet and outlet inserts facing up, because if not you will be only using actually 50% of the tru cool😞

Is it recommended to be installed on Chevrolet Tahoe 2017?? Any side effects after installing it? On which temperature does it keep the gear oil? Hi

Perfect I’m getting me one this week thanks man

very nice. I am getting ready to do this on my 2006 sierra also

Cool video, petty straight to the point. Thank you

Good little diagrams man good video

Love that dash cluster

I agree great job thanks man im going to try mine this weekend.thanks brother

This MIGHT be a stupid question, but I'm a teacher and I ALWAYS say: the only stupid question is the one not asked. So here goes: why does a vehicle need a transmission cooler?

Very good video my man 🤘🏻🤘🏻

hey bro nice vid, did your engine go over 210 at times when you had the stock cooler? and if so did this fix it?

Clean install thanks, hey Do you think is the same one to install it into a 2009

I'm just connecting to the two lines already out there using 3/8 brass compression couplings

Hey I live in Philly would you recommend bypassing the radiator or no

What gauge cluster do you have? Looks awesome!

Nice vid carnal, but that engine sounds like it needs some work.. I hear knocking noise.

Do you hava a link to where i can get this exact tans cooler?

and as aces so that the clouster transmission marker works correctly

Thanks man very helpful 👍

I seen that someone drilled out the 3/8 holes to open them up more for better flow any word?

Thanks Jose.

did your fingers burn at 8:53? 😭 thanks man helped out a lot

Hi, is the original coolant enough only after being removed from the water cooler

@joseflores what did you use to plug up the radiator where your lines used to connect? What is the part called/where can I get it. Thank you

Do you need more trans oil since it’s more bigger ?

Very clean and creative install. I’ll be installing mine exactly how you did it, thanks

Good install video

Do you plug the fittings on the bottom of the radiator ? Does it leak if you don’t?

Do you have to plug those transmission connections on the radiator or is it fine like that?

What if I still want have that line to the radiator. Because here it gets cold

Great video !! can I use that system for my 2003 yukon denali bro?

i have a dropped silverado like yours, is it recommended to do this?

Nice rig! What cluster is that man?

I live in OKC and I have a 2012 Silverado 1500 Z71 4x4, Im kinda confused on the thermal bypass....If the transmission lines run to the radiator to get the trans up to operating temps, then I wouldnt need the bypass?

I live in OKC, in the winter it can get pretty cold sometimes. Do you think I could still do the bypass valve?

Either way the rad it hotter then the 4l60 likes 200 -210 the heat kills em they r best around 160-180

ممتاز

I was told this cooler works best with the lines up other wise you’re not getting the the complete cooling benefits of it.

Do you think this cooler would be good for a 4l80e ? think the temps will be around 150?

Nice video mate.

I’m having a hard time finding a black one. Is the silver noticeable through the grill in person?

What exhaust are u running 🏃??? Am planning on putting the cooler on my 08 silver it’s been running around 210 200 any suggestions?

Did you plug up the holes in the radiator? I'm in Texas also, so no need to heat up the fluid first. LoL, this heat is insane.

I dont have the trans temp on my cluster, how can i tell if the trans running hot? Im not doing a new cluster cause i literally put a new factory one in last month

Does the transmission temperature gauge just automatically start to work even tho your truck didn’t come with that gauge ?? The ecm will make the gauge work ?

10:16 why would you need to remove the line? just shove the end of it into the rubber hose that came with the cooler and use the included fitting to connect the rubber hose to the cooler it self and you're good to go

Hi I have hummer h2 2003 I wanna install true cool so process same ?

What's the long cooler to the right of the radiator for

Got a link for where your ordered cooler from?

So you're not running it to the radiator no more ? I just installed mine and the guy said we shouldn't connect it to the radiator as well I also got the true cool 40

What size is the hose and hose clamps ? Or does it come with the cooler too ??

What temps you getting after the install? Any improvements

I also have a 03 ext cab Silverado but mine don’t have that cluster. Where can I get a gauge cluster like your?

Is there any advantage to using both trans coolers OEM and aftermarket?

What did you plug the old radiator holes with?

I'm keeping the radiator cooler on mine. Maybe if the temps aren't as low as I want I'll bypass it. Not sure yet.

Do you have to plug the original line that went to the radiator. And how did you add the line to the transmission cooler?

Did you plug the return line on the radiator? The top line on the radiator.

What size line did you use?

how has it been running?

I got a question. I have the 03 cateye 1500 non hd. Is it posible to install the hd grill without having to have the hd hood?

Yo can you put the link to where you got this kit ? Thanks

Do you need to bleed the system since air is introduced? Or will it work it self out

What about that old line to the radiator do you just leave it open or cap it ?

Did you have to add transmission fluid after the installation?

Water cools better than air, you need both man

What is this part # nice vid bro

Do u know if this will work on a 03 avalanche that didn’t have a trans cooler factory

Got a stall converter?

What did you plug the holes with on your radiator where your disconnected the lines

Funny how u try to correct this guy when you yourself are wrong in your correction. Lol Trans fluid comes out and goes into the radiator HEAT EXCHANGER then into the external transmission cooler then back into the trans. Ideally want your transmission fluid 20 degrees on average cooler than the engine coolant temp right? Now for example your coolant temp is running at steady 210° and you want your transmission fluid temp at 180. ( The cooler the better when it comes to trans fluid ) so the hot high pressure coming out of the trans say at 220° It then flows into the radiator heat exchanger and comes out the other end at 200° because the coolant in the radiator is at 210° Then it flows into the external transmission cooler in front of the radiator and it further reduces the trans fluid temp to 170° and goes back into the transmission at 170° and then comes out of the trans at 220° and the process repeats. The external cooler is much more efficient at cooling than the heat exchanger. It would absolutely not make any sense to do it how you said. If you go to the cooler first straight out of the trans at 220° then into the external cooler and it gets down to 190° (assuming your transmission cooler is efficient) then you run it through the heat exchanger and the coolant is at 210° it would then heat up the transmission fluid To say 205 due to the the engine temp and back into the transmission just to heat up more. And continuing the cycle. Long story short is why would you pull heat out of the trans down to a certain level just to have the coolant increase it l.

By any chance do you have part number for this exact one? Or the link to where you got it from thanks!

what did you use to cap the radiator?

Did you plug the hole where you deleted the transmission line from the radiator??

For what is the bypass valve?

What do you put in the radiator for the thermal bypass when you run the lines straight to the cooler? Is there any plugs or something I need to buy?

do u cap the trans inlet to the main radiator?

How much cooler does it keep the trans fluid?

Where can i buy it?

What did u use to plug the radiator

Does the cooler allow the fluid to get to the right temp in the winter?

Any update on the trans? Has it lasted?

Sorry to tell u, you installed this cooler udside down, that means you are only utilizing only about 20% off this coolers capacity. Look closely at the instructions and states how to install this cooler.due to the design of the coolers internals you must install with fittings on top...other than that i like your idea of eliminating the radiator.

Does it matter if you have the transmission cooler up or down

150 160 range????

How has this help long term my guy?

Was it your first time doing it?
