We just bought our T@B S Max a month ago. We have been towing it with our 2004 Honda Odyssey van, 298k miles, original transmission (crazy, huh!). We put a class 3 hitch on with trans cooler. I read that it's best to only tow in D3 and never use overdrive. We made it from Virginia Beach to Columbus, OH that way but wow did it take a long time and really cut into our gas mileage (rpm's ran at about 3500). But then last week my trans gave out and now I'm in the market for a new van. I'm looking at more Odysseys but now in the 2007-2009 range with under 100k miles. Do I still need to tow in D3 with these newer models? Is it possible to tow in D4 if the newer model vans come with it? Does anybody know much about towing with the Honda minivan? I love the reliability of the Honda and want to stay with this make and model but I'm just not sure what to do from a towing standpoint. Can anybody shed some light on this issue? Thanks in advance!

If the manual states to lock it out, by all means do so. Otherwise, be your own judge.

Locking out the torque converter translates to a 1:1 ratio between engine and tranny rpm. Optimal towing to reduce tranny wear is a 1:1 ratio (overdrive off). If you have a 5-speed, 4th gear may give you a 1:1. 4spd, 3rd gear may give you a 1:1. Look in the owner's manual for specs.
My rule of thumb is if I am going up even a slight incline I keep the tranny at a 1:1. Flats I will try overdrive. If car begins to shift a lot I drop back down to a 1:1. I also run a Scangauge II so I can monitor tranny temp and water temp. (Factory gauges are not that reliable).
I live at 6800 ft msl and commonly tow up and over 10,000 ft msl. My towing habits will differ as with every 1,000ft of elevation gain an engine will lose about 3% horsepower, unless you have a turbo forcing air into the engine (in simple terms).

It's been a year since we bought our T@b max S. Started with an '04 Honda Odyssey van as stated in my first post. It stranded us about 3.5 hours into a 7 hour drive home last Labor day weekend. After it cooled off we were able to drive again-I was the problem-messing with OD when I should have just stayed in D3. We sold the '04 to a local farmer we do regular business with...it's still running great at 300k+ miles. We bought an '09 Honda Odyssey last September and put all the towing junk on it and we have had no problems as long as we stay in D3 and don't exceed 60 mph. We've gone camping about 7 times this season so far...short and long distances. I'd really like to drive faster than 60, but I'm not in the mood for a bigger, gas guzzler/diesel to do it...or a bigger car payment!
We drove both and we knew we wanted a tow capable vehicle for "someday" as we keep our vehicles 10-12 years and at the time we were thinking pop-up camper. We picked the Highlander for day to day comfort but in retrospect I think the 4Runner would be a better choice for towing and hauling camping stuff on road trips. One downside of the Highlander is wasted space for a third row seat that would only fit munchkins.
