Transmission Cooler Recommendation for a 2007 Chevy Suburban Towing a 5,900 Pound Travel Trailer

Question:

My 2007 Suburban is having a hard time towing a travel trailer. The trailer is well under the max tow rating but my transmission keeps getting to hot when I tow the trailer. Will the weight distribution hitch help to ease the strain on my trany. My trailer ways 5,900. My suburban is rated at 7000

Adding weight distribution will help to divide the gross trailer weight more equally to all the axles of the Suburban and trailer, but all the weight will still be there. While weight distribution is a good idea for a trailer this size, the best solution, and most economical, is to add a transmission cooler.

I recommend the Derale Dyno-Cool Tube-Fin Transmission Cooler Kit, # D12903. It is rated for up to 6,000 pounds gross trailer weight and will help to keep the transmission fluid in the optimum range of 160 to 200 degrees F. You will also need fitting # D13035 for installation.

I have included a link to our FAQ article on transmission coolers and a link to a video showing a typical installation.
