I have a 2008 Civic with Auto trans and have towed it 4 down for over 12,000 miles in the past 6 months without any issues. I read a post that gave Honda's suggested procedure for preparing the transmission for 4 down towing. Basically, it's slowly moving from Park, through Reverse, Neutral, Drive, D2, D3, back to D2, D, and finally to Neutral again. Turn key to I and turn off all accessories (lights, radio, etc.) and lock the door behind you with an extra key. You are ready to tow. I run my engine for 10-15 minutes before hooking it up and may restart and repeat procedure along the trip if I'm exceeding 300 miles in a day's travels. My Civic was paid off, so I decided to use it rather than trade it in on another vehicle. Hope this info helps.
