Well built installed solid with brackets worked well. Would have gave it five stars except they gave me three feet short of the 3/8” rubber hose. Had to make a trip to the auto store to buy 4’ more

Had to get a fitting to adapt it to my radiator, but overall I'm averaging about 70° cooler when towing with my 2011 suburban.

This cooler is actually too big for my car. But then again, I have read that the transmission in my car does not like too much heat.The added capacity and after adding two extra quarts of trans fluid is keeping my Trans a happy Trans.I also installed a shift kit. It shifts faster now and therefor less friction and less heat.It is winter time, so I am going to reserve the right to modify this report. Ambient temperature will have a bearing on how this Trans performs.I may have to go ahead and perform more surgery on the patient. In that I mean new shift solenoids, etc. But it's a major job and one I do not wish to do. My car is a 2006 chevrolet impala ltz

Un boxed it and it seems to be high quality. Haven’t put it in yet but I see no problems. Came with everything I need to put it on.I would recommend this product. It looks better than the high priced ones and it’s large unlike the small ones selling for more money. It’s like twice the size of most which means more cooking.
