Quality cooler - Hayden 678
Installed on a '05 Taurus after having the transmission replaced. Very well constructed and the 4.5 ft. length of hose is high quality, also. A little disappointed with the hose clamps, though. I purchased #8 fuel injector hose clamps to use instead. Installation on the Taurus is tight in front of the condenser coils. I opted not to use the plastic zip ties because the fins on the condenser are so tightly packed. Instead, I used brackets, top and bottom, to suspend the cooler on the left side about a 3/8 inch from the condenser. Hose length was exactly right.Verified purchase: YesCondition: New

Trasmission saver
Lowered my transmission temp about 20 to 30 degrees. This in turn lowered my engine temp about 15 degrees. I was having heat related transmission trouble after driving long distances. This cooler has solved all of the problems I was having. This is a great product and wish I had one sooner. I also recommend the Hayden 679 extreme duty cooler.Verified purchase: YesCondition: New

Well worth the time and effort.
My 2007 Chevy Trailblazer's transmission was running at 215 degrees in stop and go traffic, not good for the fluid or the clutches. It took a couple of hours to install because some plastic had to be trimmed and the included straps had to be bent just right to keep the cooler from contacting the radiator and other hard surfaces. The included hose was too short for my application so I bought a 10' length of 3/8's hose at a local auto supply store. Take care to route the hoses away from sharp edges and zip tie them so they don't rub against the frame or other sharp objects. After the install the temperature has consistently been between 165 and 180 degrees. We'll worth the time and effort.Verified purchase: YesCondition: New

Great transcooler
I bought this cooler cause my Dodge Caliber stock is insufficient to properly cool my transmission especially in the jot weather. It is now 60% cooler. It wasn’t easy to install but it wasn’t hard either. I changed my fluid at the same time. It takes approximately 2 quarts more now. I do not have a pic after everything was installed because i had to put car back together before it stormed

Temperature drop
I have a 2014 toyota tundra 5.7 , i also have the bully dog tuner installed and i can monitor my transmission temperature. Since installing this trans cooler, my transmission temp is now 150 degrees instead of previously 190 degrees. Works great!Verified purchase: YesCondition: New

The cooler the better for trans fluid!! Buy it!!
Great cooler, dropped trans fluid temp by 12 degrees in my 72 chevy pickup. You'll need to buy the correct radiator fittings to make it work. Listing doesn't state that there are several kits that help with the installation. Other than that, a super product.Verified purchase: YesCondition: New

Seems to do the job.
I have this on my modifed g35,bypassed stock cooler. I was worried the stock cooler would leak and cause damage. I had a smaller cooler before that was thicker then this and got slightly higher temps when running hard on 90f+ days(peak ~200f). Have had it installed 2 days and it hasn't been as hot out but I have only seen output temps of 97f so far. Seems to keep the trans cool,perhaps a little too cool. Install on this car was kinda difficult in this car due to the size of it but is manageable.I recommend this cooler so far so good.Verified purchase: YesCondition: New

Using as a fuel cooler
I am using this as a fuel cooler in a very hot engine compartment (V8 engine, Jeep CJ5) and a fuel injection conversion. Hot days, constant return of hot fuel to the small (10 gal) tank is causing vapor lock issues. Still in the experimental stage, but I can attest that the restriction is minimal to the fuel flow and the quality is excellent. Were I looking for a trans cooler I would have no hesitation to use this compared to the older tube and fin coolers.Verified purchase: YesCondition: New
