What the hell does that button do?

What the hell does the "poer" button to the left of the steering wheel actually do? How about the overdrive button on the shifter? How about a good aftermarket exhaust for my "dent machine"?

 

the overdrive button puts you into fourth gear at highway speeds, saves gas. with the overdrive off, you are riding around in a 3-speed automatic. Just leave the overdrive on unless you're towing something.

 

ahh yes but wht about the "extra power button"?

 

I have an "ECT" button where you describe that gives a little more acceleration by changing the shift points of the auto tranny. Stands for "Electronically Controlled Transmission" or sumthin like that. Just keeps the tranny in the lower gears longer before shifting during acceleration. Prob only useful when trying to pull out into congested traffic. I haven't used mine yet other than to see if it worked.

 

yeah my ex's truck has the power button and it actually helped with like mountains or hauling too... raises the shift points just like mentionede before which also means it stays in the gear longer for hills...instead of kinda hunting for right gear like they can do sometimes.. noticed lower temps on hills in tranny with power button on
