I don't think it matters whether you have paddles, steering wheel buttons, or "+" and "-" on the shift lever - they can all do the same thing. In some vehicles, they control manual shifting, but on others they just move one step at a time between the classic automatic transmission selector positions (leaving automatic operation active).

Even the classic PRNDL-style shifter can do the same thing, if it is convenient enough to move; although this will usually still be automatic with an upper gear limit, rather than completely manual, that's usually what you want anyway when towing. That generally works fine in my Sienna.

Barry, do you mean it locks up only in 5th with the button in overdrive mode?

This is a good point - you can get some programming changes - like with tow/haul - as well as blocking overdrive. Unfortunately, you are also blocking that top gear, even if it might be desirable at times to use it.

My Sienna will lock up the torque converter in at least 4 and 5, and I think 3, even with the shifter in "D" (which means use any of the 5 gears); it does not have a tow/haul mode or "overdrive" button.

Since every transmission and transmission control program can be different, this is a situation which calls for reading the owner's manual to understand what selections are appropriate and what transmission behaviour will result.

Yes. Locks up only in 5th with overdrive on and only in 4th with overdrive off.

When towing I always turn overdrive off and have found that I get better mileage by doing so. When I get to a hill I release the gas pedal momentarily, this unlocks the torque converter, then take the revs up to 3000 which is the max torque for my engine and rarely ever have to downshift to third by driving this way.

Our Tundra has, like Donna's, a button at the end of the gear selector that you push to "turn overdrive off". I'm going to defer to Brian as to how it does what it does ....
