Transmission question

I have a 2008 NA auto and was wondering if it is normal for it to shift quickly through gears at fast acceleration? Shouldn't it rev to redline before it shifts?

Good question and I believe it should get close if you're at WOT. Someone with an auto who can chime in?

It should be shifting near to redline on full throttle runups, but I would suggest that there is some lag in our instruments so that it looks like it's shifting earlier.

YMMV

I had expected it would be programmed to change gears in such a way that max tq is available.

After 40 mph, it tends to "drop" to the next 3 gears fast, wonder if i get a scan tool , can i program the shift points? Just annoying that's all.

A scan tool won't do it. I would suspect that there is something wrong with the car, not that the shift points need to be reprogrammed honestly. How long have you had the car and has it always done that?

What a scan tool will be able to tell you is if you are actually at full throttle.

Maybe the previous owner did some programming to change the shift points?
