When I am going downhill, I sometimes drop the tranny to neutral and coast much of the way. Is it bad for the automatic transmission to be popped in/out of neutral and/or left in neutral for extended periods?
Why in the world would you want to shift to neutral and coast?

I'm not sure I'd be willing to risk damaging an automatic tranny by coasting in neutral like that, but I do it all the time with the 5MT in my '02 Elantra. It's one of the fuel saving techniques I've used to average 33.2mpg over the last 99,000 miles versus the car's 21/30 revised EPA numbers. If you've got a long downhill stretch where you don't need to use engine braking to retard your speed, you can save a lot of gas. Before they put in a couple of traffic lights, I used to coast over six miles on my daily commute from the top of the Palmer Divide clear down past the infamous Ted Haggard's New Life Church (Ted being infamous - not necessarily the church) on highway 83 here in Colorado. Traffic was always very light at 5am and I never went more than 10mph over or under the limit.
You might want to check your local laws, though. I don't know about California, but it's technically illegal to coast in neutral here.
Thanks to all for the great info on TSX mileage. I've about settled on one as my next ride. I get the feeling that it'll be a lot harder restraining my right foot in an Acura than a Hyundai, though!

i wish that were true but my husband tends to speed more in our 05 hyundai elantra GT 5 speed than he does in our 06 acura tsx 6 speed. we also get good gas mileage in our elantra-average 33.5 mpg. it has just over 60,000 miles-

I picked my new 08 6spd TSX up about a month it ago. It was my third car (till my Civic was stolen last weekend) so I only filled it up twice. The first tank was about 27mpg, and most of the miles were highway (bought the car in VA, drove it back to NJ). My second tank was 22mpg, and according to the MID this one's not going to be much better...
I don't get it. I don't floor it, and always shift at around 3k rpm's..75% of my driving is highway, 25% city.

Give it a few more tankfuls to even out fill variations. However, don't expect stellar MPG in NJ or anywhere else in the Northeast - ethanol blended gas used in these areas will drop your MPG by 5-15%.

Had mine for 1 month. Best mileage (highway) was 34. Mixed driving has been around 30. Using mid-grade without any issues...

My new 2009 TSX automatic trans, mixed drive highway and local is about 27, it should be better because my wife do not have a light foot. we live in Dallas, it is flat, so there is no up hill or down hill. But there is some traffic jam, so I think this number is pretty good.
