Question:

I just purchased a 2017 toyota sienna van. I would like to tow , does the transmission cooler D13503 Meet the OEM trans cooler specs. I dont want to void my powertrain warranty if I dont have the right cooler or equipment. Toyota dealer didnt seem to concerned, but if theres a problem its not their pocketbook.

While we do offer transmission coolers with a superior design in comparison to the factory transmission coolers neither of our aftermarket transmission cooler manufacturers Derale/Flex-a-lite were able to provide information as to what transmission cooler meets OEM specs. The supplemental coolers we offer are just that, supplemental meaning they are designed to be used in addition to the factory transmission cooler. However, I can honestly say I have never heard of people running into warranty problems after properly installing a supplemental transmission cooler. According to the Magnuson-Moss Warranty Act, "It is illegal for companies to void your warranty or deny coverage under the warranty simply because you used an aftermarket part unless that product caused the problem."

With that being said, I recommend using the Derale Series 8000 Plate-Fin Transmission Cooler Kit part # D13503 for your 2017 Toyota Sienna. The standard transmission coolers equipped in most passenger vehicles are of a tube and fin design. This cooler has a plate and fin designed which will exceed the performance of your factory transmission cooler. The kit comes with everything needed for installation and I have also attached a review and installation video on a similar vehicle for you.
