When in hills towing or not I do the same as I was taught when learning to drIve; downshift to keep from overheating your brakes and running away. Still do it, works fine for me. Going uphill I'm not concerned with maintaining a certain speed and dont mind slowing down and staying between 3 and 4000rpm. Seems much easier to me. Maybe I'm misusing my equipment but it has never caused a problem. Tried the tow/haul a few times, didn't like it.

EDIT: I just read the Technical Training Tip of the Month posted by HighMobious. Ok, maybe I'm an old fart stuck in my ways but, with doubts, I am going to try this out as we tow our car more often than not.

As for me personally if I'm towing/hauling I use tow/haul, if not I don't. For many downgrades I set my cruise and let the engine do it's work.

I totally agree.

So is he saying that you will get lower MPGs but should hit OD/Off or Tow/Haul after every start anyway?

No, he's saying buy their DuraTrans and BrakeMax systems

It reads to me that it is an issue of economy vs performance and you have to decide what is best under the conditions.

I posted the article because of the explanation on how tow/haul works.

It sounds to me like he's saying that's an option to having to do it manually each time you start out, but doesn't contradict the previously-made lower fuel economy statement.

I believe some of the points made regarding torque converter lockup also don't apply to newer 6R140 6-speed transmission.

Quote:
Keep in mind that the intention of having overdrive gears is to improve fuel mileage. To get that improved fuel mileage you need to get into that overdrive gear as soon as possible, and stay there as long as possible. As a general rule, automatic transmission electronic strategy is to get you into the highest gear possible, and lock up the torque converter as soon as possible for a given engine load. EPA test methods for fuel mileage testing and ranking of OEM vehicles does not currently allow for the pushing of a button during the test to “allow” overdrive. The test must be done by dropping the shifter into drive and off they go. If the vehicle started with OD off / OD cancel / Tow/Haul engaged, EPA fuel mileage ratings would suffer.

You can take advantage of the benefits of the transmission control strategies associated with the transmission control switch by remembering to hit the button or switch every time you start your vehicle...or...you can contact InterMotive about our DuraTrans and BrakeMax systems that perform that function, and more, for you.

There are two solid advantages for tow mode: one, it holds each gear longer on acceleration and if you are in the mountains or "heavy" as most RVs are this can be quite convenient at times to minimize the number of times the transmission has to shift and; two it puts the transmission in a mode to downshift each time you tap the brake. It does not, in itself, cause a downshift or overdrive lockout, it just makes it super easy to select a lower gear for engine braking when in mountainous country. Just try it a few times and see if you like the results. I'm quite sure lots of folks never use the feature and may even not know it's there- and they get along fine without it!

Actually, on my 2015 F53 chassis when I get off the Interstate and start braking down the ramp the transmission downshifts early to assist the braking with no action on my part.

Also, while on cruise control, if I go down a long hill and the coach goes 5 mph over the set speed it will downshift to slow it down.

Let's face it automatic transmission is just a lazy mans method to shifting. However in many cases its much better and consistent in terms of using the right pattern for all of the mentioned reasons. So the question really is are you better than a computer assisted machine. If you are get a stick shift if not ...
