No power compared to 2004 Gen4 V6

[2014 Warthog]

There used to be an transmission eco/pwr mode switch in older vehicles, I had it on my 04 taco. Switch said "ECT" and when pressed the dash would say "POWER".

I believe when switching between normal and "S" Mode shifting, this performs a similar function. Keeps the tranny locked up more and at higher revs.

Also, if you really hammer the throttle, even in normal shift mode, it also goes into a power mode where you'll notice that even backing off to a lighter throttle the RPMs will be kept above 2500 until you really let off on the gas and then it drops back to eco mode with RPMs kept at about 2k or below.

So I think the eco/power modes are there fully alive and well, just that they automatically switch now in some cases rather than being completely manual like before. And instead of a switch, you use the shifter to go into "S" mode if you want to do it manually.

There is no "power" mode. There is no "eco" mode. It is a light that illuminates if you are within some range of driving parameters, nothing else. The "S" mode allows you to select the shift point. That is all. There is no "hidden" mode(s).

It also hangs onto high gears way too long, so you can be going up a moderate hill, and be using 50% throttle, but in 5th gear, so not only are you getting nowhere, but you are dumping a bunch of extra fuel.

I like the ability to get up to 95% engine load in 5th on the interstate. It's not dumping a bunch of fuel, it's more efficient than downshifting to 4th or opening up the torque converter. If I need more power, I simply push the skinny pedal a bit more to downshift.

A 'sporty' throttle map give you power without the ability to save gas. A conservative throttle map allows for economical driving and power driving, depending on driver input - the best of both worlds.

I'm not talking about the light. The light is merely something that turns on below a certain engine load and nothing more.

But there ARE two distinct ECT modes that can be activated manually (And has been for at least 10 years) or automatically using gas pedal behavior in newer models.

Try this: Keep your gas pedal constant and switch from normal to S mode you will notice that your RPMS will climb as it usually downshifts as it locks the converter. And not just from 5 to 4 either, I've seen it happen from 4 to 3 and 3 to 2.

You can also try the stomp on the gas going up hill, get it to quickly downshift, then notice how it keeps the RPMs at 2500 instead of 2k even if you ease off the gas you let far enough off on the gas and then it'll change back to eco and use 2k as the shift point.

[Edit]
Not that I think about it, it's probably not 2 distinct modes any more (It used to be) The control over the shift points and lockup is probably more linear from eco to power as the ECTs are getting pretty smart these days. Though at times it does jump from a higher "power" mode to a higher eco mode with enough of a jump to be quite noticeable.
