Question:

Id like your recommendation for a tranny cooler to replace the stock cooler in my 2005 Chevy 2500HD, 6.0 liter engine with the 4L80E transmission. The stock cooler lets the trans run at 210 normal towing and has gone as high as 280 pulling my 9,000 lb trailer over the Blue Ridge mountians. Id like to see it run much cooler...

Good call trying to reduce your transmission fluid temperatures. The cooler the fluid is the longer the transmission will last.

The best way to pick out the best cooler for a vehicle is to measure the area in front of the radiator/ac condenser and select the largest cooler to fit there. It also helps to get a stacked plate style cooler as they are the most efficient and pretty small in size. I attached a link to a page that has all of the stacked plate coolers we offer.

I also attached an FAQ article on transmission coolers for you to check out also.

If you have room for it, the Derale Series 8000 Plate-Fin Transmission Cooler Kit # D13504 that you referenced would also be a decent choice as well.

If you do not want to mess with cutting or flaring metal lines you may also be interested in purchasing Derale Radiator Adapter Fittings for GM # D13018.
