## Customer Reviews

### ⭐⭐⭐⭐⭐ Ever see that transmission temp top 200?
*by S***Y on August 1, 2024*

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...

### ⭐⭐⭐⭐⭐ Decent cooler
*by D***R on April 12, 2023*

The media could not be loaded. Used with a 4L80 with a 3200 converter.Good cooler for the money, the mounting hardware is okay if you get creative. I’d recommend different hose clamps as these strip pretty easy even if you don’t get it as tight as you think it should be. Overall I’m happy with it. Keeps temps to 130-140 in standstill traffic when it’s 90 out even while being routed through the radiator cooler. Would recommend to anybody that doesn’t want to spend the extra money for a real tru cool, this one works fine.

### ⭐⭐⭐ Short and fake hose, sensitive thin mesh.
*by Y***R on March 30, 2025*

Looking good, have the fittings and other hardware. The hose is very short, absolutely not 55.2 inch, significantly shorter.P.S. After day of driving suddenly detected the strong Dexron flow from the under the car - the hose included with the radiator exploded. Don't use the included hose, buy good one for the work under the pressure.
