do i need a transmission cooler to pull a trailer on a 2009 town and country?
Always a good idea.
It really depends a lot on how heavy is the trailer, how far will it be towed, how often, what kind of driving will you be doing with the trailer on? Hills, mountains, flat land, etc.... To agree with sonnybear47: it's a good idea considering the above mentioned. If it's a light 4x4 utility trailer, putting a cooler on is a waste. But if you're pulling a large camper/boat, it's a must.
see above answer. and if you aren't on level ground, it's also a good idea to turn off overdrive when towing the cooler can only do so much.
