4.5
Installed on a 2007 Suburban with 5.3L engine, and 4L60e transmission. Quick installation, and it made a huge difference! I should have installed this years ago. My tranny used to run at about 180-200 degrees, depending on outside temps, and speeds. If I was towing a trailer, and/or traveling at 80mph on highways with hill it would usually creep up to 215 or so, which always made me nervous. Since installing this cooler I have yet to see it go above 140! I’ll be towing a heavy camper late next week, and that’ll be the big test, but I’m pretty confident it’ll stay well below 200 for ever now. Great product!!!As a tip- the threaded connector it comes with does not fit the Chevy radiator. I used a Harf line cutter and a beveler to splice into the metal hard line, and create a beveled end to prevent leakage. Also- the kit comes with 4 feet of hose, which would not have been enough for my install unless I had curved the hose in a smaller arc than recommended. Go to the auto parts store and get amother 3 or 4 feet of 3/4 inch hose. Mine required about 3 feet for both in and out feeds.
