Larger transmission cooler- E450 October 18, 2014, 06:09:42 pm Yahoo Message Number: 149054Early last summer summer, Andy told me about a larger transmission cooler he had installed in his LD. I didn't pay much attemtion until I had a chance to see the specs and measure the stock cooler...wow, the thing looked huge in comparison, at twice the size of the stock cooler, now I was interested! http://www.amazon.com/gp/product/B00803CTDA/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1This is an involved project that took a good six hours to do to our 2003 FL. It required modifications to existing brackets and some new brackets plus a lot of plumbing.In the end, it was worth it. https://www.flickr.com/photos/lwade/sets/72157648794273051/The cooler was installed in late June, just days before a 4th of July trip to the Eastern Sierras and Mammoth Lakes. Within a couple hours of leaving home, it was apparent that something was wrong, as the trans temp were higher than usual. A quick road side stop showed the thermo valve was in full bypass and the cooler wasn't receiving any hot fluid. A infrared thermometer made the diagnosis quick and painless. A stop at the autoparts store in Bishop provide the needed parts to ditch the bypass-valve. Once done, the temps dropped to where I had hope they would be. We now have 5000 miles on the new cooler, recently returning from a month long trip up to the PWN. There were plenty of very long, steep upgrades in blistering 105+ temps. Pulling a 4000-lbs Jeep, the peak temps ran a good 10 degree cooler than before, under the worse of conditions. I'm pleased.Larry As an Amazon Associate Lazy Daze Owners' Group earns from qualifying purchases.
