After installing this Tru-cool knock off it is performing well and has dropped my 6L80 transmission temp an average if 30 to 40 degrees. While pulling a 7000lb boat with outside air temp around 90 the temp never got above 160. HOWEVER I would strongly recommend that you DO NOT use the cheap non rated hose included. After two weeks it randomly ruptured and left me stranded after I discovered the leak. It dumped about a gallon of fluid on the road before I noticed the transmission slipping. Luckily I was able to immediately pull off the road and shut down. I had to get a tow home. Get a $10 section of J2076 oil rated hose from your local parts place. I should have known better so you've been warned!!

Install this and those days are gone. I installed before last trip to mountains pulling a trailer. In the past I would see temps of 220-230 degrees on the transmission. Highest I ever saw this past trip in miserable outside heat was 194 degrees. Longest transmission life comes with keep it just above 160. Without a load or super steep hills I routinely run about 162 degrees with this on a 2007 Suburban with 4x4 and 5.3L engine. Do it, it will save you money on powertrain repairs...

I replaced my factory cooler with this for a upgrade as the transmission is just rebuilt.

Just installed 10/27 no leaks so far but the fins are extremely fragile several bent with the water hose pressureUpdate as of Feb 8th the oil cooler failed on me . The sides started leaking a large amount of oil between the fins . This wasn't dropped but it looks like it caved in in the center somehow .when it worked it worked great but not at the expense of almost losing a transmission and replacing the trans fluid

Got this thing as a temporary replacement until i got the new TRU COOL MAX 40,000 GVW Transmission oil cooler low pressure drop & turns out to be same exact unit only half the price. This thing works keeps trans oil at 130° & before it was at 190°/200°. You do the math glad I got this

Product showed up with minor fin damage taking 15 to 20 minutes to repair.Most people would have simply ignored it as it was small, but I’m a perfectionist. The fitting size is a mystery, could be 11/16-18 or 17, possibly 18mm 1.5When I have determined the proper fitting I will update this review to help others with installation who want a more professional look installation than patching in rubber hose. I plan to use -6AN fittings and anodized aluminum tubing custom fit with no rubber to decay over time.

I put a diverter on the supply line and can use either the rad or the cooler. I installed a temp gauge and can see the rad reaches 190°F- 220°F but switch to the cooler and it doesn't budge off of 100°F
