Great cooler, and amazing results! About 40 degrees cooler!
Installed on a 2007 Suburban with 5.3L engine, and 4L60e transmission. Quick installation, and it made a huge difference! I should have installed this years ago. My tranny used to run at about 180-200 degrees, depending on outside temps, and speeds. If I was towing a trailer, and/or traveling at 80mph on highways with hill it would usually creep up to 215 or so, which always made me nervous. Since installing this cooler I have yet to see it go above 140! I’ll be towing a heavy camper late next week, and that’ll be the big test, but I’m pretty confident it’ll stay well below 200 for ever now. Great product!!! As a tip- the threaded connector it comes with does not fit the Chevy radiator. I used a Harf line cutter and a beveler to splice into the metal hard line, and create a beveled end to prevent leakage. Also- the kit comes with 4 feet of hose, which would not have been enough for my install unless I had curved the hose in a smaller arc than recommended. Go to the auto parts store and get amother 3 or 4 feet of 3/4 inch hose. Mine required about 3 feet for both in and out feeds.

Works perfectly
Wonderful product, used it on my 2012 altima known for overheating transmission issues, definitely helped. I could feel the amount of heat on the cooler, and verified actual temperature drop with snapon scantool. It dropped the temp by 15 degrees F stopped at operating temperature, and it lowered around 20-25 F at steady 70mph. I mounted it on the very front of my AC condenser for most air flow.

Modifications required
This aftermarket item was installed on a Toyota Settings 2008. I added it in front of the Condensor coil. I had to drill two 5/8" holes in part of the frame for the hoses to connect back to the transmission return line splices. Just remember to connect the hoses prior to adding the zip ties. All in all it works fine. I added it because I added a tow hitch to the minivan.

Great replacement
Replaced my stock 4l60e transmission cooler for another one. The other one failed after 6 months, so I decided to go with Hayden. Hayden products have been around forever it seems, all my buddies suggested this one when the other failed. Super simple install and definitely keeps the fluid cooler

Works great as a compressor aftercooler!
Though I can not say if this products works well as a transmission cooler, I can certainly vouch for its use as a compressor aftercooler. I have this unit installed on a Kobalt upright compressor from Lowes and it works great! To be specific, it is installed between the compressor and the tank, along with a moisture collector, to cool the compressed air and keep moisture out of the tank. This means no water in the tank (less problem with rust) and no water in the compressed air output (a good thing....!). The unit comes well packaged and includes the necessary connections and install parts. Seems well constructed too.

Super fluid cooler
If you want the best transmission cooler 😎 this is the best I had a factory cooler replaced with this one

Two deep cuts on one of the u-turn bends. Do your due diligence of inspections before installation.
UPDATE, June 17, 2022: I’ve received the replacement cooler fairly quick and today I’m hoping to install it on my vehicle. Although it appears the cooler is overall very well made I was so frustrated and upset to find out there are two deep cuts on one of the u-turn bends (pictured) when I was ready and very eager to install it on my vehicle today. When I first noticed them I thought they were only superficial scrapes - mere corrosion resistance coating scrapes, however, upon close examination it was very clear that they were deep, especially one. Though the cuts aren’t all the way through, it’s not difficult to imagine should you install this on your vehicle the thinned cross-sections at the cuts when subjected to high pressures and temperatures of the transmission fluid as well as gradual corrosion that further thins the the thickness, the cuts would more likely leak eventually leading to significant transmission fluid loss and subsequently putting you at a greatest risk of ruining your automatic transmission and subjecting you to all the huge expenses as well as all the inconveniences that comes with it. I’m surprised how this passed Hayden’s quality control inspections at the factory, or don’t they have one? Therefore, do your due diligence in inspecting the cooler for defects before you go ahead and install it on your vehicle. Also, due to it not being packaged properly two sets of fitting adapters in their small plastic bag move around the box bending the very thin/delicate aluminum fins. Though those bends can be straightened with little effort and patience, all that trouble can be avoided if Hayden implements a better packaging practice. I’m returning this defective one to get a replacement. 3 stars I gave it is solely because of poor QC and defects discovered, otherwise the product seems to deserve 5-stars.
