Honda Odessy Van

We have flat towed our 2003 Honda Odyssey over 50,000 miles without problem (knock on wood). We do change the transmission fluid more frequently than recommended for normal driving just as a precaution depending upon how far we have towed it that year. We also stop and run it through the gears again after towing no more than 220 miles. That fits nicely into our rest break/change driver schedule anyway. We also don't drive over 70 miles per hour - normally between 55 & 65.
