Sport mode question
 
If I am in the sport mode will the car still shift if I don't ? If I take it to redline and I don't shift will i hit the rev limiter or will the z shift on its own at this point ? I have a auto trans

You will get more responses if you put more info about your car, what is it MT or AT?

Obviously an MT car will not shift on its own so I assume you are AT...........

I don't have a AT so I can't help you :tiphat: :wtf2:

While we're on the subject...

7AT / Sport / Touring. If I use the paddle shifters, it only holds it for like 8 seconds before going back to Auto. Do I need use the lever & swap modes to get it to hold the gear? I've just never jacked with it... Using the paddle shifters seems pretty worthless since it won't hold the gear.

If you have it in the manual side on the AT7 it WILL NOT shift by itself. It will allow you take the car to the redline and that is it. It will bounce off the redline but it will not shift.

I remember doing this when I had my AT7 and was passing someone and forgot I was in the manual side.....:facepalm: .

The paddle shifters are really for the "manual" side of the AT7. Yeah you can use them in the auto side but I'm sure they are meant for that. It does take some getting use to in the manual side because you would assume that clicking it down would shift it up but it's the opposite. The down is down and the up is up.....gets a little interesting when you have above stock hp with the shifting.
Try it and drive it. I always had it in the manual side....seemed more fun.

Slide the shifter left. You will have uninterrupted control.

The 7AT will not upshift on its own when in Manual/Sport mode. In Manual mode, it will only downshift on its own. You will bump the engine's rev limiter if you don't manually upshift.

Thanks...that's what I need...uninterrupted control. :)

I'd just never played with it except for the paddles. Hold them until it goes to manual, but then you've got to keep shifting to keep it in manual.

Tigger 04-12-2013 08:22 AM

You have that option if you want to quickly go into a manual mode while just cruising along in D. It can be useful. But I already keep my hand on the shifter anyway so it is just as easy to slide it over quick and pull down two or three times and bam!! Gone, b!tches! lol

wstar 04-12-2013 08:56 AM

Just get in the habit: every time you would normally move to D, slip it one to the left into M and leave it there. Keep both hands on the wheel and use the paddles full-time. It's the least-confusing mode, and gives you full control without worrying about the temporary-paddle-shifter timeout. You only have to go back to the shift knob to pop it into N at a stop, then back into M to go again. D is just an annoying spot on the shift controls you have to move through to get between M<->N :)

4r3s 04-12-2013 09:09 AM

Why is pushing the stick forward for shifting up and pushing the stick back for shifting down confusing? I've heard this a few times now that this is confusing and it seems perfectly logical to me.

also why are you shifting an automatic into neutral when at a stop???

Zythaxus 04-12-2013 09:16 AM

I read that too and was going huh, shift to neutral.... Why.... :confused:

NickTurnon 04-12-2013 09:17 AM

The 7AT is the best.

It auto downshifts for you if you pull up to a stop sign, but will not shift into a higher gear.

If you want full access of the manual settings, the shifters gotta be pushed in manual.

If you want to pass someone on the freeway keep in automatic (D), downshift with the left paddle, and they will see your dust as you fly by. A few seconds later itll realize you aren't in manual on the shifter and will go back to auto (D).

Color me curious.

Wonka2581 04-12-2013 09:31 AM

Yes do in lighten me and everyone why so you put it in N?

NickTurnon 04-12-2013 09:32 AM

I believe you save some gas by throwing it into neutral when in auto and stopped.

I do it at long lights and when I am just sitting somewhere waiting for someone!

I was also told that throwing the car in neutral in an automatic going downhill to coast, isn't a good thing to do. I was doing it for awhile because the car would just coast forever and I never needed to use the gas pedal. Engine or something doesn't get properly lubricated.

Zythaxus 04-12-2013 09:42 AM

Also illegal putting in neutral to coast, esp downhill

Zythaxus 04-12-2013 09:48 AM

putting the automatic transmission in neutral with the engine running disengages the geartrain, like depressing the clutch pedal on a manual transmission. - note that with modern automatic transmissions, the engine must be running to keep the transmission fluid circulating; which lubricates the geartrain.*
*
however, my state and probably many others, prohibit the practice of coasting down hills with the transmission in neutral.* the logic behind this is that first, the engine helps with braking on downgrades, and reduces heat and wear in the brakes.* second, if the transmission is disengaged, then the transmission will have to be reengaged before the driver can accelerate to avoid trouble.

If I remember right, I think the 2013 I test drove DID upshift automatically for me. I think this was something Nissan changed with the refresh- maybe someone with a 2013 7AT can confirm.

Also the only time I popped my auto cars into neutral was if I was waiting for a train. Sometimes I just popped it into neutral, other times park. If you're going into N at a normal stop, it's pretty pointless unless you want to look like a manual because you don't have to hold the brake to stay completely stopped...

wstar 04-12-2013 10:23 AM

I shift to neutral at stops so I can get off the brakes. Standing on hot brakes at a light in D -> hot-spotting rotors. Not screwing up my brakes is important to me, given how much I've had with brake hardware. I don't coast in neutral :)

Mine's a 2009, they've never auto-upshifted in manual mode.

wstar 04-12-2013 10:31 AM

Example of banging against the soft rev-limiter in 3rd gear, partway through my last track vid (no auto-upshift). You'll see a downshift to 3rd going into a right-hander, then just banging on the redline in 3rd for a sec before braking for the next right and then passing that vette:

Right...but I drove a 2013 (not a 2009) and I'm pretty sure it did.

Just throwing that out there. Doesn't really matter to me- I drive in manual mode all the time...oh wait :tup:

Edit: come to think of it, I don't remember if I had it in M or if I just hit the paddles in D. Maybe that's why. I don't remember though.

While I wouldn't recommend coasting in neutral for extended periods (eg, down a long grade), coasting in neutral on an exit ramp or coming to a stop sign is not going to damage the transmission. I can't see any reason to do so under normal driving conditions, but it won't harm the tranny.

That may be the law, but it sure sounds like more legislative BS to me. Especially the part about being able to get back into gear - one can go from neutral to drive with a quick bump on the stick. Once again, it's not something I recommend doing, but it's not dangerous if one is paying attention to the road and traffic.

I thought that was really only an issue on new rotors that haven't been broken in yet but, fair enough, thanks for the explanation :tiphat:

wstar 04-12-2013 05:09 PM

It's probably more important when breaking in new rotors, but it's also important anytime the brakes are really hot. And I really don't often drive without getting the brakes really hot :)

Quit student driving and start engine braking :D Save them brakes.

wstar 04-15-2013 06:30 AM

:P I do engine brake, but the engine can't brake like the brakes do :)

Zythaxus 04-15-2013 09:06 AM

Yeah, sometimes they brake too well, I get a little nervous when a beater that prob doesn't have insurance gets behind me in traffic.
