I started towing my 2008 Element (auto, 2wd) 5 months ago I only have 1,000 miles towing I have followed the standard procedure and kept an eye on the color of the transmission fluid all seems fine. I plan to put a lot more miles on my Element. Others at the Honda dealership unofficially said I shouldn't have any trouble. The Element makes a great toy box I can fit 4 bikes in side I just need to take the front wheel off the bikes and fold up the back seats.
