2009 Chevrolet Silverado

09' silverado 1500 5.3
Temps are down
15 to 25 degrees on test drive, No trailer. 105* heat index city, highway, a.c running
75mph 169-171* (factory 185*+)
55mph 165*
City stops 159*-163*
Idle after drive for 10 min in Sun 149*

Trimmed factory grill mount and welded on tabs, to put back in factory location (no picture of finished grill mount by itself) used factory holes on upper grill hood latch assembly. Only fault is u need to remove trans cooler to unbolt grill mount, but it's just a grill mount.


Comments
A year later all is perfect. Reworked my hose connections just to make it better. I haul my race car and gear so maybe 6000lbs my trans Temps have not seen over 190* maybe running 85mph up hill in 3rd gear for extended time it might hit 195* for a short time then after up shift it cools right back down on a hot humid summer day I plan to put a full aluminum radiator in to help just that much more.

I installed the cooler last weekend in my 2008 Silverado. I've included some
pictures.
I made a strap to support the upper portion of the cooler and thru bolted
the lower to the existing bracket.
The hood bracket lower bolts had to be cut down to 1/4" length so they would
not contact the cooler.
The lower mount bolts had to be spaced to give the hood mount weld nuts
clearance.
Now to see how it does with a trailer and the Pacific Northwest hills.


Comments
Randy, could you please forward me pictures of your install? I have the exact truck and your pictures would be helpful.ThanksPaul

2010 Chevrolet Colorado

I recently had the chance to use the Derale 8000 series transmission cooler during my last camping trip and was very impressed. I have a 2001 7.3 Powerstroke with 4" exhaust, S&B intake, gauges and a DP Tuner (60hp tow). I pull a 10,000 pound 5th wheel around Colorado. It seems like every where I pull in Colorado is up hill. It was common to see my transmission temp easily and quickly reaching 210-220 when towing mountain passes. Just before my last trip I installed the Derale cooler and the highest trans temp I saw was 190 at the top of Wilkerson Pass. What is more impressive was how quickly the temp dropped as I came out of the pass. For most of my trip my trans temp stayed around 180. While pulling in the city I saw temps around 200 which I assume was due to stop and go driving and not having the constant airflow through the cooler.

I installed the cooler right behind the stock front grill to the vertical post with self tapping screws (the grill still fits perfectly). I then used two thin strips of metal that I got from the hardware store and secured them to the cooler and to the second vertical post. I wanted the cooler in the front of my truck to get maximum airflow. I then spray painted the metal strips black just for looks. I did have to buy an additional 4' of hose due to the location where I mounted the cooler. The optional instal kit was simple. The adaptors screwed in my radiator with no problem at all. Once I decided to mount the cooler the entire project was quick and simple.

2009 Dodge Journey

2009 GMC Yukon XL towing a 7,800lb travel trailer from California to South Carolina.....
I don't believe the Yukon would have made this journey if it wasn't for the additional transmission cooler and engine oil cooler. Dragging the travel trailer through the mountains during the heat of the summer was taxing. However, my transmission never got above 190 F when it was over 100 F outside. Before installing the oil cooler AND transmission cooler, my engine temp would go to the 1-2 o'clock position and transmission temp would get up to 210 F. Highly recommend this product.

2013 Chevrolet Colorado

Hello Gang, I have a 2013 Chevy suburban and tow a 7K plus travel trailer. While we were towing to Colorado near Cripple Creek the temps were low 90's and my trans spiked at 230. Had to pull over to let it cool down. Now keep in mind my suburban does not have a HD trans cooler just the stock radiator cooler. Fast forward one year now my stock trans line is starting to leak from the rubber hose so it's time to change. Decided to order the larger trans cooler might not have been the best idea as it's larger then where I wanted to put it. So after taking off the front bumper, headlights misc brackets and lots of bolts I was able to get it up behind the "A" frame bracket in front of the radiator. Make sure if you go this route to put the rubber hoses and clamps on before installing because you will not be able to install the hose after. The bracket the holds the hood latch has openings that just happen to line up with the inside bolt holes on the cooler. Hoses facing down You will need to cut the bottom of the plastic out of the way to route the hoses under the frame. Cutting the original trans cooler line was easy and the rubber hose was long enough to make both connections so I did not need the adapter. If I used the adapter the rubber hose would be too short. On the bottom I used the foam pads between the cooler and the frame and secured it with heavy duty Zip ties. Can't wait to test it out this summer. I forgot to take pictures of the final install but did take one picture showing the "A" frame in the middle of the radiator. It fit's perfectly behind it.




by:

Everything was included to do this simple upgrade. This was the perfect size for my application. The included hose was the perfect amount but, I would have been more comfortable if I had more.

1995 Ford Van

It fit with no problem, and connecting was straight forward. We bolted it into place as the fit allowed it on our 1995 E350. The difference in transmission temp is incredible ... about 20 degrees cooler on rolling hills, and 35 degrees cooler on mountainous roads.

1996 Toyota T100 Pickup

I installed this on my Toyota 1996 T-100 3.4: I picked up a piece of universal hangar strap, 2-8mmX1.25 bolts & lockwashers at building supply; 3 gal tranny fluid (flushing system including torque converter), 4' extra hose & extra clamps @ auto supply. I first mounted flange to central member with a couple screws; then bent 17-1/2" of the strap to pass the AC line ( the holes for the two bolts actually lined up to the two factory threaded holes available!!PTL). From there it's almost a done deal; hookup the cooler to the return side out of the radiator and let a half gallon at a time pump out till you get new fluid: then make up your return hose to the steel return line. It's oversize but this is FLA and it pulls. Heat is death to transmission fluid; and then the transmission! Good project.

Truck sold to friend- heard no bad report. Thanks

I didn't do a proper before and after test to see if this was an improvement over the factory transmission cooler on my 1999 Chevrolet Express 3500, but it certainly looks like it would be more effective than the stock setup. Installation was easy and it fits great in front of the stock radiator.




by:
2012 Chevrolet Suburban

The hose that came in the kit was about a foot too short and should be 3/8 id. I had to source my own longer 3/8 transmission cooler hose. Other than that, the quality of the cooler appears to be good.

2008 GMC Acadia

Great value for the price and free shipping, package arrived on schedule, was packed extremely well, (I would know, retired Postal mail carrier), Derale 13504 transmission cooler was exactly what was described should work well for me to tow a 3500lb travel trailer with my 2008 GMC Acadia. Will be installing the cooler this week. This definitely should keep my transmission from over heating, it's rated somewhete at 22500 GVW. My vehicle and travel trailer CGVW is approximately 9000 lbs.


Comments
The Derale 13504 has kept my transmission from over heating, have towed my travel trailer over 3600 miles no problems with transmission over heating in my 2008 Acadia SLT. Will be installing a auxiliary fan in front of my radiator to assist when in towing this summer. .

We have been very happy with the performance of the transmission cooler. There was a significant drop in transmission temperature after replacing the stock cooler with your product when pulling our camper. Very easy to install on our Chevy pickup.

2014 Chevrolet Silverado 1500

The installation was not too bad. Make sure you order the correct adapter. The adapter it comes with is universal so I had to order a GM adapter after I started the installation. It mounted really clean on my 2014 Silverado. Worth the money for late model GM’S to keep the transmission heat down.




by:

The hose attachments worked perfectly. I did not think it best to use the tiewraps attachments so I made metal brackets and screwed them to frame materials. The cooler seems to work perfectly.

2008 Chevrolet TrailBlazer

We've had it for a year in our 2008 TrailBlazer 2WD with 4.2L inline 6 cylinder. I think it's about the largest that would fit and we got it for a towing our 21' expandable camping trailer that can be about 4,500 lbs. max. Works great, although I added another install kit to be sure I had enough hose and the extra brackets and connection adapters. I did not want to use the mounting parts that poke through the radiator and A/C condenser fins, so I got the Derale kit with brackets and hose in an affordable kit together, part # D13006.




by:

Went together easy, works as advertised. Mounted front and center for most efficient cooling capacity and it does the trick. Dropped my trans temp by 40F without a trailer. Have yet to put it to the test with a heavy trailer long distances.

2009 GMC Yukon

I installed this trans cooler on my 2009 Yukon. The installation video really made it much easier. I just pulled my boat under the same conditions I had prior to the install and I am very pleased with the results. Prior to mod, my trans temp got up to 204 degrees. With cooler, it was 160-165.

1999 Chevrolet Silverado 1500

I’ve had the Timbren suspension enhancement system for a year now on my ‘99 Dodge 1500 4x4. I purchased this product because I had to tow my bumper pull three horse trailer from South Carolina to N. Central Montana. With a camper top, the bed loaded and the trailer loaded the truck sagged really bad. With the Timbrens on the sag went away completely. Making for a much safer less stressful experience while towing.




by:

Hardly any difference in flat land driving temps. Perhaps 5°to 10° cooler is all. Pulling my 10K camper any grade at all and temps still climbed. Mountain passes on any day over 80° , the trany still gets over 200° quickly. On the plus side the cooler seems to recoupe quicker than the stock one. 2009 Chevy gasser .


Comments
A normal operating temperature for your transmission fluid is between 175-225 degrees F. Adding a transmission cooler effects every vehicle differently based on a number of conditions - such as if youre towing, how heavy a load youre carrying, the outside temps, etc. From what youre describing it sounds like the results youre seeing are keeping your transmission running within that normal range. Even while towing close to your max capacity over the mountains on a warm summer day, your transmission fluid is still at the sweet spot of 200 degrees F.

I bought this because the transmission temp in my 2013 Avalanche was hitting 220 when towing a boat. Which seems high. After researching I found that transmissions in those models are ok up to a maximum of 275 degrees (which seems crazy but it is rated that high from chevy. There’s a website called Silverado.com that has a lot of info ). I installed this product and it worked really well. Easy install with the video if you have mechanical ability. Dropped temps by about 30 degrees. Still working great no problems. Only concern I have is that the transmission temp stays pretty low in the winter. It’s working well though. I would highly recommend this product. Good products, good service!


Comments
still working great! I would highly recommend . I have had no issues and would use this product again. I am in Indiana and the trans temp can stay around 120 in the winter but I have had no issues.

  • Should I Add or Replace the Transmission Cooler for 1998 Dodge Ram Pickup with 5.9L V8
    It is most likely that your truck already has 2 coolers for the transmission fluid to go being the radiator followed by an auxiliary cooler. Once the transmission fluid goes through both of those and then back into the transmission, if your transmission is still overheating I recommend replacing that auxiliary cooler with a bigger one and the Derale Series 8000 Plate-Fin Transmission Cooler part # D13504 is a great option. The plate-fin type cooler is a great option over others because...

  • Adding Transmission Fluid After Installing Derale Transmission Cooler in 2017 Chevy Silverado 1500
    Thank you for your purchase of the Derale Series 8000 Plate-Fin Transmission Cooler Kit # D13504 for your 2017 Chevy Silverado 1500. To answer your question, when adding fluid you will want to first check the fluid level with the vehicle started and in neutral. You will likely need to add some to top it off, so simply add it as needed; there isn't a specific process for adding fluid on a vehicle with a thermometer in the transmission system. It's really just check and top off as needed.

  • Transmission Cooler Replacement Recommendation for 2005 Nissan Xterra
    Sounds like you are wanting to bypass the transmission cooler of your 2005 Nissan Xterra to prevent the known issue they have of having it leak into the radiator. We can easily help with that. What you'll want is a replacement supplemental cooler to bypass it with something like the # D13504 and you'd be set. This would do a better job than the factory cooler sine it's larger and a more efficient design and would allow to no longer have to worry about the milkshake issue.

  • Does it Matter Which Transmission Fluid Cooler Line is Return Line
    With transmission coolers like the Derale part # D13504 you can use either barb fitting as the inlet or the outlet and the cooler can be installed in any orientation and it will still work great. So if you wanted to run the return line from your factory cooler to the bottom barb like you mentioned it would cool the transmission just as well as any other orientation.

  • Transmission Cooler for 2016 Chevy Silverado 1500 with 5.3 liter Engine
    The factory cooler of your 2016 Chevy Silverado 1500 does not have a thermostat to keep the fluid at 190 degrees. That just happens to be the temperature the factory cooler keeps it at mostly since it's built into the factory radiator which does have a thermostat. What this means is that the engine's coolant thermostat is indirectly acting as a thermostat for your transmission fluid. So an aftermarket cooler will install after the factory cooler and will then do a great job keeping the...
