Nissan Murano CVT
Jerry G.
I am curious to know... When at a light waiting for a few minutes, is
it harmful to put the CVT in to neutral?
Also, if approaching a stop, and if the vehicle is rolling at less
than maybe 5 mph, will it do damage to the CVT to put it in to
neutral?

I own a 2008 Maxima with a CVT and I suspect that I have put it in
neutral under many different situations (although I don't know why I
would have) without doing any harm.
OTOH, why would you want to put it in neutral at a stoplight even if you
were there for several minutes? I have put it in "park" while waiting a
long time at a car wash, but neutral?????

wash since the car wash mechanism moves your car through it automatically.
Now I'm not so sure why you would want to do it at a stop light!

I know nothing about CVTs, but does the CVT have hill-hold like the
automatics have?
I drive a standard shift (5 speed) and I just depress the clutch while
holding the brake pedal down until I get a chance to move..

it doesn't hurt them to put it into neutral when you're stopping
somewhere,so why should it hurt at a light,as long as the car is not
moving?

What purpose is that for?
actually,you can put an automatic into neutral at any time.
I guess it's necessary if "unintended acceleration" occurs(runaway/stuck
throttle).
I once put an auto tranny car into -reverse- when I began sliding on ice
and couldn't brake to a stop before hitting the car in front of me,it was a
pushbutton shift 63 Dodge Polara.It worked,I stopped immediately and even
began going backwards,didn't hit the car in front of me.
I don't think you can do that with modern automatics.

does the CVT have a torque converter or an electric clutch?
Torque converters have "creep",clutches don't.

For hillholding,I use the handbrake that is between the front seats;that is
what it's designed for.
Generally,auto trannies don't need hillholding,they already have enough
creep built in,except for really steep hills.

I also did that when braking on snow or ice downhill. With the foot on
the brake, shift into reverse and apply gas.
I last had to do that in about 1996 in a 1995 Ford Crown Vic.
That's when I had to drive in snow or icy conditions.
Now, I just wait for the highway dept. to clean the roads.

When I am just coming to a light that I know will be a long one, I
like to put the vehicle in to neutral so I don't have to keep my foot
firmly on the break to stop it from rolling forward. Sometimes a light
can be a few minutes.
Sometimes the vehicle has been still rolling about 3 to 5 mph while I
am slipping it in to neutral and still gently applying the breaks to
reach the full stop.
I was curious to know if this would cause damage with a CVT.
I was told by one mechanic when driving along at let's say 30 mph or
so, with any automatic or CVT transmission, coasting it in neutral is
not good practice, and especially if the driver puts it back in to
Drive while still moving along. I would also like to verify if this is
true...

That one mechanic who advised against neutral in CVTs and ordinary
automatics? Questionable. I've put regular automatic trannies in
neutral at 50 to 60 mph and re-engage often. The tranny smoothly
engeges the gears with no issues whatsoever. No massive thunk or
disconcertaing feeling at all. Putting a car in neutral is good for
the auto tranny because heat is the biggest enemy to the tranny fluid,
and the tranny fluid is the life blood of an automatic transmission.
When you leave the car in D while at stoplight the engine is sitting
there pushing against the tranny, warming up the fluid. Of course the
tranny fluid is not overheating, but it is getting warmer than if it
were in neutral. By putting the car in neutral you give the tranny a
chance to cool down because you;
1. remove the load from the engine, and
2. let the car idle a a slightly higher rpm which circulates more
coolant which cools everything down, including the tranny.
I suspect that CVTs are also vitally dependant on their tranny fluid
so they would want to reamin cool as well. At a stoplight I would put
a CVT in neurtal. At speed though, I can't really say.
To Bill (wilshak),
I used to hold the clutch as well while braked at a stoplight. Once I
changed my clutch and got a clearer understanding of whats' going on
inside, I changed my habit. When you have the clutch depressed, you
are engaging the throwout bearing, wearing it out. By putting your
manual tranny in neutral and letting go of the clutch and holding only
the brake, you are in the best position of least wear to your tranny.
It would suck to wear out your throw out bearing before the clutch has
worn out because replacing the clutch or the throwout bearing involves
open heart surgery to your tranny. I had a 5 speed maxima and my
thowout bearing got incredibly noisy. You could hear me engaging gears
from 100 feet away:) When the throw out bearing is worn, that gear
whining noise as you engage gear goes up significantly. The car kept
working but I knew I was on borrowed time and I eventually bit the
bullet and changed the clutch, replacing the throwout bearing as well.
