curious about ECT button

I have a question related to the ECT button. If I understand correctly, it helps the transmission shift more efficiently than it might normally. Is this close? I read that it will shift at lower RPM's and that it will lock out of overdrive until the engine is warm. With that being said (assuming it is accurate), is there any problem with leaving it on all the time? Also, does leaving it on affect gas mileage in any way? Any help/advice will be greatly appreicated. Thanks in advance.

 

I think (but I'm not sure) you have it backwards...when on, the tranny shifts at higher RPMs. At least that's the way it feels when I have it on in my 02 with a 3.4L.

 

When I had my 99' with the ECT Power I always had it on. Or I would turn it on when I would go to pass. With that smaller engine it makes a good amount of power at higher RPMs so having the engine shift higher helps with acceleration.

 

Yep, you guys got it right. It increases the shift point, for a more useable powerband.

 

yeah i kept mine on most of the time since i drove mountains a lot and had a heavy foot, oops, but it didnt really affect my gas mileage, my foot affected that haha, i miss that button.

 

Yup, it shifts the tranny at higher RPMs, good for passing, towing or mountain driving I guess.

 

What do you mean it shifts at higer rpms? it you drop it to first or second you can shirft just at redline..Does it help to get increase the speed. and you cant have the ect on when in overdrive?

 

I would reccomend dropping into first at 65mph. Just hit the ECT button and the shit point raises about 500-800 rpm from usual. Yes, it works in OverDrive

 

ECT stands for Electronically Controlled Transmission. When you push the button in, a light on the dash will indicate "ECT POWER". This changes the normal shift times (based on engine vacuum, rpm, and throttle position) to a later point, and engine RPMs go higher before shifting to the next gear while accelerating. It helps build speed more quickly, but uses more gas to do so.
