Your cart is empty.There’s no greater enemy for a transmission than heat. Whether your 2014+ Chevy Silverado/GMC Sierra 1500 V8 is a dedicated tow vehicle, hardworking fleet truck, or a daily driver, you need to ensure that your transmission runs cool. Luckily, Mishimoto has developed a cooler to do just that. Our 2014+ Chevy Silverado/GMC Sierra 1500 V8 transmission cooler utilizes a stacked-plate design for maximum durability and powerful cooling. The Mishimoto transmission cooler mounts inline with the factory cooling system to add an extra 0.65 quarts of transmission fluid and over 3,000 square-inches of surface area for a significant increase in cooling potential. Included with the Mishimoto transmission cooler are adapter lines that connect directly to the stock cooling system and a relocation bracket for the ambient air temperature sensor. CNC-machined mounting brackets and high-grade transmission cooler hoses make installing this transmission cooler a breeze. Also provided with this kit is a thermal bypass valve delete that allows fluid to flow to the cooler at all times; making this cooler ideal for drivers in hot climates. Like all Mishimoto products, our 2014+ Chevy Silverado/GMC Sierra 1500 V8 transmission cooler is backed up by our lifetime warranty with accident Protection for worry-free cooling as long as you own it.

After doing research on the Chev 6 speed trans weakness, I decided I needed to reduce the operating temperature. There are a lot of coolers and thermal bypass products out there and many (most?) are cheaper, but this was advertised as being made specifically for my year Silverado. It fit perfectly, all the lines connected as they should have. The included thermal bypass parts also went on as designed with no issues. The truck only has 43k miles, and has had minimal towing but fluid that came out was very dirty, so I did a fluid/filter change at the same time. Prior to installing this unit, my trans ran about 195° on an average day. Considering the fluid runs thru the radiator that runs 210°, that's probably typical. But everything I read says that temperature will limit the trans life to about 100k miles. After installing the unit, the trans temp was holding 125° with ambient air temp at 89°, so I'm quite happy. Yea, it's expensive, but as they say, pay once/cry once.

Kept temp below 150 degrees on my 2017 Chevy Silverado 1500 LT while pulling RV travel trailer.Before the transmission temp will reach 220 in spring here in Texas, but now it ran like a champ.

Installed on my 2018 Yukon Denali with the 6.2L L86 engine.Once the front end is removed installation is relatively simple. The project is not difficult but does require complete removal of the bumper cover/grille assembly as one unit. There are many fasteners to be removed. The entire job took me about 3 hours in my driveway.After I installed the cooler I gave the cooler a coat of flat black high temp Rustoleum spray paint. I called Mishimoto support and verified that this would not affect the cooling.1st image is with the cooler installed and the 2nd is after giving it a coat of spray paint.The important part - cooling !!!!I use my Yukon to tow a tall travel trailer and it came without an external transmission cooler. Living in Colorado, the mountain passes really put a strain on any transmission and before I installed the cooler the Yukon transmission temperature would climb to 205F with the 3,500 lb trailer in tow.After I installed the Mishimoto cooler I saw maximum temperatures of 170F, a 35F decrease under load!Since installing the cooler I have done multiple trips with the travel trailer and the performance was incredible. On one trip I was towing on I-40 near Needles, California with the ambient temperature of 105F and my transmission temperature was a nice 165F - it doesn't get any better than that!This is my second Mishimoto transmission cooler that I have installed and both coolers performed great. The other vehicle was a 2003 Chevrolet Suburban 1500 with the 5.3L engine & 4L60E transmission.

Super facile d'installation et fonctionne vraiment j'ai le bypass pour le thermostat d'une autre compagnie et ma transmission se maintient a 60 degrés celsius l'été!

This is the quality I expect from mishimoto.Mounted on a 2019 yukon (which they say won't fit due to the break in models that year) and it was a breeze to install.Anyone who is not mechanically inclined will have 0 trouble installing this (getting the bumper off might be another story)HOWEVER the instructions do suck. I'm used to it with mishimoto.Youtube/google/ or mishimoto website has better instructions with pictures.Transmission has also not seen 145f or above since.It's been 1.5 months in Texas...

It arrived in good condition.Exactly as described.Very high quality, as expected.Easy install, good instructions.Dropped my transmission temperature 30*f!Hopefully this lengthens transmission life.

The item it supposed to be kit specific for Silverado 2014+ but I received my item with only the transmission cooler core and aluminium lines. With all other parts missing (mounting brackets, high pressure lines, thermostat valve delete, installation note card , stick on drilling template, quick disconnect fittings) all of those parts are missing

Install is clean with decent instructions, however I recommend the youtube install vid for guidance. Complete kit, sturdy mounting. Clean looking when mounted/better than other coolers I've seen. And it really drops the temps. In 100 deg weather my trans was running 145 deg. Really good in my book. not a cheap item, but good.

I took this cooler my 2016 Silverado to my local transmission shop and had it installed. The gentleman at the shop said this is one of the nicer units he’s ever seen and was surprised that it was as cost effective as it was. I wanted to have it installed because I had just replaced the transmission on the truck.TemperaturesBefore EMPTY NO TRAILER: 198-210Before WITH TRAILER (HAULING JEEP WRANGLER 2DR) (7,000 LBS): 208-220After EMPTY NO TRAILER: 131-145 it doesn’t hold a the higher temp for long and like a to drop down to the 135 area for a consistent 75 MPH.After WITH TRAILER (7,000LBS): 145-165 at 65-75 MPH. Have to text on the mountain but the hills of. I-25 in Douglas County Colorado make it seem like it will be just fine!I can’t rate the easy to install because there were a few additional things they needed to done because of previous work on the truck and I didn’t do any of the work my self to the truck. However the shop said that if it were just a stock truck it would have taken him about and hour and a half.
