Modern automatic transmissions have so many gears the efficiency is usually better than a manual for the average driver, plus they can be manually controlled gear-to-gear without a clutch involved. I was a manual devotee until I moved out west where there are a LOT of hills/mountains. Love having cruise control for the flats too!

Plus add big time to brake wear!

It adds nothing to brake wear.

Everyone seems to power to stop lights only to have to activate their brakes even when they can plainly see the light is red or about to go red.. I plan ahead and roll up when possible barely needing to tap my brakes.

On down hill runs I avoid using my brakes and use engine braking where necessary and possible.

Interestingly the Odyssey behaves in a similar fashion though not going into neutral. On practically any down grade it shuts off cylinders and approaching stop lights it immediately drops to 3 cylinders when I take my foot off the gas approaching stop lights. In the latter case popping almost immediately into the 50 mpg mode.

I haven't had a stick shift since the '80s, because DW can't (or won't?) drive a stick.

I have always towed a lot, especially while working (self employment). My 2000 Mercury Mountaineer has about 190k miles on it, and well over half of those miles were put on while towing. My 2008 Highlander has over 140,000 towing miles out of 170k total. Neither one has had any transmission or drive line problem. Some fluid leaks to reseal, that's all.

My theory is, if a person locks out OD as necessary for towing, does fluid/filter changes on time, and doesn't mistreat the machine, the automatic transmission will tow just fine. No doubt some trannies here and there will give out prematurely, but that may or may not be caused by proper tow use... it might have given out anyway, bad parts or poor tolerances or bad karma or whatever.

Norm,

How do you use engine braking if you shift to neutral going down hills and approaching stop signs / lights ( as you said earlier )?

Glen,

For reference, I'm writing about the CRV, the Odyssey is a totally different situation. With the Odyssey I never shift into neutral while moving.

Most of the time I dis not use engine braking at stop lights because frequently I saw they're going red. Heck I see people power up to stopped traffic and then apply their brakes. I rolled in neutral in that situation.

Down hill I stayed in neutral as much as possible and never exceeded the speed limit or my tire's top rated speed, 65 mph. If I saw speed building beyond appropriate limits I put the car in gear. I virtually rolled home from Crater Lake averaging over 30 mpg towing the Scamp.

Of course what I do is always dependent on road conditions, the road, weather and traffic level. A very high percentage of our travels are on low traffic density roads.

Charlie,

Our new vehicle has a 6 speed, many vehicles have even more. To me it's the magic of the transmission and the variable cylinder management. Here in FL I'm almost always in ECO mode and frequently that means the Odyssey becomes a 3 cylinder vehicle. True efficiency.

Tomahto/TomAto... band/clutch
Ford had select shift on their automatics forty eight years ago.
I have had cruise control on every vehicle I have owned since the late 1970s.... All manual transmissions.
Why only on the flats?

We wound up with a 16' Scamp due to weight issues with the CVT in a 2006 Ford Freestyle. A regular auto-trans or manual would have not had the 2K lb tow limit.

After always having a manual I am still not used to the "Ahem" fuel savings... of the @$%*%^ thing accelerating down hill as it freewheels rather than using engine compression to maintain speed.

I was able to drive an International Scout with a broken clutch cable into the jungle for our research and more importantly back out again 3 months later by synchronizing RPM and "crash boxing" it. Guess my racing experience in my younger days in Formula Fords paid off [IMG]file:///C:\Users\Bruce\AppData\Local\Temp\msohtmlclip1\01\ clip_image001.gif[/IMG]


Actually the auto in the current Ford is great as my wife is comfortable driving it, although she was excellent in the jungles with our manual gear boxed 4-wheel drive like the last Mitsubishi Montero we kept alive for 16 years.

Our thinking with our new Scamp is that we will use the Ford Freestyle until it drops and if necessary and if we still like Scamping we can always get a new tow rig.

Interesting discussion for sure.

Way to go Batdude...... You know what your doing. I had the same thing happen on a semi... the clutch pedal rod broke and i had to drive it from edison nj to west point ny and back.... roll up to the toll booths in neutral then shut it off, put it in 1st gear and crank the starter and off you go, or just grab the shifter with two hands and give it a good jerk into the "Low Hole", which i really don't like to abuse my equipment like that and as you know synchronizing the rpm's for changing gears up or down. I still do it often today in a little suzuki samurai i have.
Automatic are still nice for comfort and ease of use with todays auto really advanced

My 2013 Tacoma downshifts when I tap the brakes and slows down gently. On a steep long downhill I downshift to get more engine braking. (Like that 18% at Manic5, remember Norm?) When I coast to a stop light, the engine RPM is down to 800 - 900 immediately. The new transmission controls seem to have some good stuff programmed in them.

I just spent three weeks driving stick in the old country. Have no problem doing it, but find the automatics with torque convertors much more comfortable, especially towing and on long trips. I would say the automatic keeps the engine running more efficiently than all but a few exceptionally skilled drivers.

Sorry to hear that Norm as you are missing the reason "they" don't want people doing that. If your engine should die/stall you loose your power steering and brakes and possibly control. Certainly not worth trying for a bit more MPGs in any road conditions. I think we have all had an engine die while idling at one time or another. I've only had one running at speed quit and fortunatly I was on the flat and the car was manual steering and brakes. No harm, just a tow. With all the electronic gizzmos on cars today I wouldn't be suprised if a blown dome light kills the whole system .
Of all the safety issues the folks here talk of, IMHO this rates in the top three.
