buddie has a question
 

alright guys,
one of my buddies just got 86 pickup, auto. He noticed that down next to the shifter there are 2 buttons, one says normal, and the other says power. first thing in my mind was overdrive, but then i remembered overdrive is on the side of the shifter. so what are these buttons for, are they even factory??

thanks for the help

THat button either takes it out of overdrive or is on off for lock up torque convertor. My guess is overdrive

its to switch the gearing in the tranny for economy, or power. at least thats my understanding of it.

He is on the right track. It will change the shift points. It will stretch the rpms higher between shifts. It doesnt give you more power....lol That is what the TRD stickers are for...lol

I've never driven an auto yota, but if it's anything like other vehicles, it's an economy button. When switched to power, it moves the shift points 200rpm higher. So instead of shifting at say 2200rpm, it'll shift at 2400rpm, thus giving you a little more get up.

^^Thunder stealer. Lol

thanks guys. nice to know, guess its time to get back to school work...NOT ha

hmm... so, its like the sport mode on my moms buick?? hit that button and her supercharged Buick Regal GS dang near redlines every shift... without it, its a dog... which is fine for my mom, but not for me and dad... :hillbill:

Hahahhahah^

Except you're wrong. The ETC power button engages the supercharger. :banger: :guitar:

Like has been said several times already, the transmission is electronically controlled. The normal and power buttons change the shifting characteristics of the transmission.

With the power button pressed, the transmission shifts at a higher RPM at any given load. It also keeps the torque converter unlocked longer, giving you some additional power due to the characteristics of a torque converter.

It also kills your fuel economy. I did a test, driving a tank on normal, and a tank on power. I think I went from 18mpg down to 14mpg.
