I can't downshift into 1st when in manual mode because I don't want my ears to bleed and I wouldn't want to break anyones windshield behind me with the sonic boom!

kenchan

but you already got faux GTR paddles... you dont touch that?

you see, AT guys make no sense to me.

Jordo!

You can downshift it if you want. You just have to learn at what speed and RPM the ECU will automatically drop it down (varies for each gear) and downshift before that -- otherwise you'll end up kicking it down a gear lower than intended.

Note that the ECU learns your shift patterns, so after driving in M mode, it may feel a bit herky-jerky in regular auto afterwards. Not something to worry about, just an FYI.

You can shift over to M while driving without hurting anything, and can even use the paddles to up or downshift while in auto mode -- it will temporarily go to M if you do that, then will revert to regular auto after a few seconds.

I never drive my '12 sport AT in manual mode but is still very herky-jerky especially when I brake and it downshifts from 2 to 1. Do others with the 7AT feel this "jerk" or is my transmission defective? At the dealership I almost bought the manual but decided for the auto only because I have driven manual my whole life and had read that the auto was faster. However, I'm kind of regretting it now after a year because it makes me "cringe" everytime I feel this hard downshift. I recall one time as I was driving home from work when the downshift from 2nd to 1st was so violent I thought the car behind me had lightly tapped my bumper lol. Although I don't drive my Z too much (7000 miles in one year) I doubt my tranny is going to last more than 5 years.

i pretty much only drive mine in manual mode but in either mode the downshift from 2 to 1 is usually a pretty decent jerk. i think it's just because the rpms are usually pretty low when it does shift down and 1st gear is 4.924 and the manuals is 3.794. the auto 2nd gear is closer to that lol 2nd in the auto is 3.194

it really doesnt bother me though. im just used to it i guess.

Ok thanks. I've kind of gotten used to it as well but it just seems that some days its worst than others. I guess it depends how I drive that day lol.

FPenvy

i dont mind it really since the first and second gear are so mean off the line i dont care about the bit of harshness when stopping lol

sounds weird to me. i shift it into drive when stopping because it does it so smoothly. shouldn't jerk at all.

danelonson

See this is what worries me and leads me to believe that something's not right with my car. This is not the first time others have told me the same thing, that in drive it shouldn't jerk at all.

critical

Just to make sure.. You aren't using the paddles or the stick right? And you're in D and not M? Only time it jerks is if I manually shift from 2 to 1. Maybe reset the ECU? Idk maybe that'll do something. Mine is as smooth as butter.

FPenvy

Those came with it. Also they are literally the exact same ones that are in the gtr.

Sorry we don't make sense but its fun to see you MT guys in my rear view mirror
