"How To": 02-06 Chevrolet Avalanche Derale Performance 8000 Series Transmission Cooler Installation

- Adding an auxiliary transmission cooler to your automatic equipped vehicle can greatly extend the life of the transmission. Keeping the transmission fluid temperatures well below the 200° mark is vital, and the Derale Performance 8000 series cooler is a tough one to beat when comparing quality, cost, and performance. Other larger coolers may be able to bring those temps down further, but for a vehicle that doesn't see much towing use, this is a fantastic option to consider.

Hello i coudnt picture one thing , the hot fluid to the aux cooler joints from the lower side of the aux cooler as i understand , then to the up cooled fluid to the radiator up then radiator down and to the transmission . Is it more efficent to connect from upper side of aux cooler ?
It’s all pressurized, so efficiency isn’t an issues
Thanks for the info! Confident I can do this now
Awesome! It’s an easy job to do. Just be sure to not lose those retainer clips for the transmission lines.
@@takeroadslesstraveled6505 thanks man. Really appreciate the video. These trucks are getting older so I’m sure more and more people will be watching. Even if they aren’t replaying or thumbs upping at least you’re helping fellow Chevy guys out
do these transmissions get hot quick going up hill?
What size hose is needed for the Avalanche ?
would it not be better to come out of the radiator than to the external cooler? the other way it's heating it back up to radiator temps before going back to tranny.
Set it up the way the instructions said to do it.
Thanks for video Man wher can I get that adapter for the hose ? Thanks
I purchased it off etrailer.com
Hey Question- On The other side of the radiator what are those line hook ups for ? Cheers Ty
If you mean on the driver side, there shouldn’t be any hookups. The power steering cooler sits in front of the radiator on the driver side, but there shouldn’t be any lines running into the radiator on that end.
If you’re talking about the passenger side, on the back side of the radiator you’ll have the feed and return lines for the transmission cooler, as the video explains. On the front side of the passenger end, you may be thinking of the A/C condenser lines. That’s the only thing I can think you’re talking about.
@@takeroadslesstraveled6505 I Have this one. I was thinking for oil lines maby ?

If you do have lines on the driver side, it could be an oil cooler.
Do you top off, with how much transmission fluid ?
You will have to add some fluid, but it all depends on what size auxiliary cooler you get. For the one I used in the video I had to add about 1/2 quart.
@@takeroadslesstraveled6505 Got it, yes I'm planning on using the very same one. Great info 👍 Thanks!
Lemme make sure I understand. The fluid is diverted from the radiator to the aux cooler then back to the radiator. If this is correct does it occur to anyone else that once the fluid returns from the aux cooler to the radiator it reheats to the same temp as if the aux cooler wasn't there? If this aux cooler isn't keeping the fluid cool enough on its own it's under sized. Get a bigger one or better yet do a electric fan upgrade for better airflow and gain horsepower and better cooling at the same time. Love the rest of your upgrades!
@@rdainwa1 i was thinking the same thing..whats the point of adding that cooler when the fluid is going back to another cooler behind the radiator that is most definitely getting heat soaked. Like comes out hot gets cooled down then gets heated back up and sent back in
@@rdainwa1 The "hot" tranny fluid should run from tranny direct to top of aux cooler where it cools then drifts to bottom outlet of oil cooler, Heat rises right? Doesn't hot engine coolant always enter top of radiator and leaves the bottom? Doesn't factory tranny connection connect to top of radiator? Aux coolers are the same. Then it heads to the radiator to be warmed back up to engine temps.. Why? Simply because transmission needs warm oil to keep destructive moisture from accumulating/mixing into oil. Imagine if you will running in below zero temps so tranny cooler is sending very cold fluid back to tranny. Not good. Tranny cooler removes excessive heat which keeps engine from overheating but if it does remove too much heat the fluid is warmed back up to normal temps that transmission is designed to operate at. Good video, Thanks.
You should’ve had the coolant flow through the radiator first, then go to the top port on the auxiliary through the bottom part, and out back to the transmission.
No, because it’s a heater and cooler.
