Universal 12'' Dual Pass Aluminum Finned Transmission Oil Cooler

Purchased this cooler for my 4l80e transmission. (5.3 ls 4l80e foxbody mustang swap). Package arrived bubble wrapped and packed tightly. After opening and inspecting cooler I was impressed with the aluminum welds and how well the unit was put together. I was also impressed with how clean it was . Installing the NPT fittings was no issues and sealed as they should. I did use AN fittings instead of the nipple fittings that came with the unit. Holes were machined perfectly. Mounting brackets were welded nicely on cooler as well. My transmission stays cool with no leaks. I give this product 2 thumbs up and 6 star rating. I recommend this product to anyone. Product has no burs on it and has very smooth surfaces. Very nice piece

I installed a single pass unit as a secondary transmission cooler on my 1990 Ford Bronco - as it is 24 inches long in manufacture simple brackets and used stainless steel 1/2"-13 lag bolts in the front bumper to mount the cooler inside the front bumper. I monitored the temperature for quite a while, a year or so, and it really helps reduce transmission temperature by 5 to 7 degrees depending upon outside temperature. This amount may not sound like much but it actually is significant in extending the life of the transmission. In mounting it I not only used the aluminum brackets holes but also placed two stainless steel wire bands as secondary mounting loosely mounted around the fins - I did this as I did not fully trust the small aluminum brackets - now having said that the aluminum brackets came in bent on he first unit so I exchanged it - but I have to tell you that this product is well worth it and works very well. I would recommend it to anyone who uses it to get the single pass with 1/2-inch AN fittings and I also bought on Amazon the hoses and fittings. Great product
