I have a 2003 Chevy Suburban 2500 with just over 100,000 miles that I recently purchased. I use it around town and tow a 4500# trailer. Recently I was towing in the Northwest hills of Connecticut and the truck's OEM transmission temp gauge showed 200 degrees, which is the highest I had seen. It usually runs around 140 when the temps are below 70 and progressively higher when the outside temperature is greater. The weather has been around 90 for a few week and I see temps of 180 or 185 without a trailer. I decide to add a cooler and seeing reviews it looked like the quality of Hayden was really good. I even called them and they were very helpful suggesting the 678. I opted of the 679 to get even more cooling.
Installing posed some options. My truck came with a factory cooler about 1/3 the size or the 679 and mounted on a plastic brace that was then mounted on an aluminum cross member just behind the grille. In order to efficiently use the OEM cooler I needed a fit kit, which my local Pep Boys carries, so I went there rather than waiting for delivery and got a Hayden kit 390 as the instructions indicated. Good thing I didn't order it, because it turns out I needed a kit 393. When I went back to Pep Boy I decided the scrap the OEM cooler and buy another Hayden 679, which wouldn't need the fit kit, and mount them next to each other. The cooler I bought at Pep Boys was made in Australia and the cooler that came from Amazon was made in Korea, but the quality appeared similar to me. Fully installed, my coolant flows from the transmission to the radiator, then to a Hayden 769 and then another Hayden 679 and back to the Transmission.
Yesterday it was 100 degrees and I took a long drive with no towing load but 6 passengers. Prior to the cooler I would expect to see 185 and the warmest the gauge showed was 150, but was running at 135 most of the time. I would say the two coolers reduced the temps by 40 degrees. Excellent results for an easy job.

I've been running with only this fluid cooler for a year and a half now. My aftermarket transmission controller (TCI EZ-TCU) monitors and displays the trans fluid temp, so I am able to know at a glance if there is any reason for concern. But even through the desert heat here in Utah, I have never seen my fluid temp go above 165^ F... ever. This large Hayden cooler does its job very well.
If you are looking for a way to reduce your automatic transmission fluid temperature, my experience says this is a great way to go. The 679 is an excellent value. I would recommend it to anyone.

Connected to the return line of the original oil cooler in the radiator. From the Hayden 678, with a shortcut (see photo) reconnected to the return line. The advantage of this is that I can now easily change my transmission oil and that the oil in the original cooler and the Hayden are also refreshed.
The Hayden 679 mounted in front of the condenser of the air conditioning in the flow of the radiator and radiator fan (see photo).
Have NOT measured the difference in temperature, but have noticed that the automatic gearbox, under the very harsh conditions, continues to shift shock-free. Automatic has now run 186,411 miles.
Longevity Hayden 679. I can't judge yet. Haven't had the cooler for that long. But the Hayden 678 still looks like new and I used it for half a year. But have full confidence in the longevity of the Hayden 679.
