This is a stupid Question but.....
Since this is my first Automatic car ever..... What does Overdrive do? What does Normal ECT and Power ECT do? As far as performance wise what would I use for the 1/4 mi.? I am assuming one is for fuel economy. Oh yeah, the car is a 1992 SC400. Again this is kind of a stupid question but, I just have always had vehicles with manual transmissions.
Thank you in advance for any answers.

In simple terms, OD is an additional gear in the transmission used primarily for cruising at higher rates of speed. Turning the OD off "locks out" that gear, or doesn't allow the tranny to enter that highest gear.
The ECT/PWR button alters the shift points of the tranny, allowing for slightly higher revs during acceleration and quicker downshifts to help the car stay within its powerband.
All of this info is readily available here on CL. The search function in the upper left of every screen allows the CL database to be searched on ANY topic. And believe me when I say there are very few topics that haven't been discussed.
This is what a search on ECT/PWR looks like.

Makes sense. I never in my life thought I would have to ask about an automatic. Kinda funny because I figured you just mash the pedal and that was it. I guess in these cars there is a little more than just pushing the pedal.

Yeah, on the 400 we need to brake torque, or power brake as we called it in Jersey, in order to get up into our powerband. The 400's are dogs off the line and any little bit of help we can give to get into the meat of our powerband is
