I would say it's a really smart idea to install a transmission cooler in your 2015 Toyota Sienna towing a 2,500 lb camper. Would your transmission blow up if you didn't install one? Probably not but you would definitely shorten it's life by not installing one since heat is the number one killer of transmissions over time.

If you installed the Flex-a-Lite part # FLX400117 in your van you'd prolong the life of the transmission by a lot.
