#24 of 84 The CVT is better than a regular automatic. by madpistol Jun 10, 2008 (10:59 am)
That "booming" that you hear is normal. You can't honestly expect a car to be perfect for under $30k. I've felt this in my car, and it doesn't bother you if you don't think about it. An easy way to cure this is to either shift to manual mode, or give the engine a little more throttle.   This car is a great car. The CVT is very responsive, the interior is nice on the S and wonderful on the SL, the ride is very sporty, responsive, and comfortable, and the car gets great gas mileage for the power it puts out. People need to stop complaining. Either enjoy the car or trade it for something else. I love my 2.5 SL, and I have no intention of trading it just because of the CVT has a couple drawbacks. The advantages more than make up for its shortcomings.

Replying to: altimaowner2 (Feb 16, 2008 10:28 pm) I have had an Altima for 1 year. 13,000 mi to date. I didn't experience weird behavior of the CVT. I expected lack of shift points to feel obvious by their absence. Not so............... However, I experience an annoying slow pulsation in "cruise" when going downhill. It is certainly tolerable, but noticeable. I assume it's the combination o CVT and throttle being confused.............. No biggie.   ..........

Replying to: sal1948 (Jun 23, 2008 1:31 pm) As a 4cyl/ 6speed owner I'll attest to the torque of the 2.5... very impressive.   The engine spins about 2000rpm at 60mph in 6th, yet when you need to accelerate more, it simply & instantly gathers speed, drama-free, like there's a giant, torque-monster Cummins diesel under the hood.   By the same token, the motor & soundproofing are good enough that I've accidentally left it in 4th gear for a few 60mph freeway miles, and only a glance at the tach revealed my error.   In 9000 miles, I've yet to feel the need for revving past 4000rpm (except to pass a long tractor-trailer on a 2-lane road).   BTW -our last tank got us 31.5 mpg (calculated by hand) in mixed city/fwy driving.   Very happy.

Replying to: sal1948 (Jun 23, 2008 1:31 pm) I have a new 2008, 2.5L Altima Coupe. Both my wife and I have experienced a pulsing between 20-30 mph. It almost feels like the transmission (CVT) doesn't know what gear to be in, somewhat like letting the clutch out a little too fast on a stick transmission. Is this normal and is this similar to what many others are experiencing? Replies to this message: madpistol (Jun 26, 2008 10:19 am) ripper82 (Jun 26, 2008 1:04 pm) madpistol (Jun 26, 2008 9:31 pm)

Replying to: dbarrett2 (Jun 26, 2008 9:42 am) I have experienced this. It's like a slight "jerking" at lower speeds. This is simply the CVT moving while the revs on the engine stays the same. There's nothing that can be done. The CVT still has set intervals that it runs at, but there are a lot more than a standard transmission, so when you're accelerating, it's so smooth that it's imperceptible to a conscious mind. This is normal operation for the car.

Replying to: dbarrett2 (Jun 26, 2008 9:42 am) Yes, that is exactly what we're talking about.   But apparently we're all crazy and should just be quiet and enjoy the jerkiness. Replies to this message: madpistol (Jun 26, 2008 9:31 pm)

Replying to: ripper82 (Jun 26, 2008 1:04 pm) I wish there was something else we could do to fix it. Unfortunately, this is normal for a CVT. It was sort of annoying to me at first, but now I don't even notice it because it's just part of how the car operates.   You have a choice:   1. Go get a car with a regular automatic that has several larger shifts that are dictated by gear placement.   -or-   2. Enjoy the Altima and ignore its slight quirkiness at lower speeds. Even with these micro-jerks, it's still the smoothest transmission on the market.
#31 of 84 2008 Altima CVT issue by greengoddess Feb 20, 2009 (6:19 am)
I have only 5900 miles on my '08 Altima but have been extremely disappointed since day 1 of my ownership experience with the CVT performance. First, there is jerkiness when driving low speeds (e.g. 35 mph) and it feels like a standard that is not in the right gear; then when driving at highway speeds (65 - 75 mph) there is vibration. Additionally, at highway speeds there is an intermittent loose steering feeling. This is my second Altima. The first - an '02 - was a superior vehicle, in fact, I still have it and couldn't be happier with performance, gas mileage, and reliability. However my '08 pales in comparison with regard to the transmission feel and performance. I've returned to the dealership several times - with limited assistance in remedying these issues. I'm told that this is the way the CVT performs. I just can't believe that vibration and jerkiness are considered adequate performance for a transmission. I'm considering filing under the Lemon Law. Any suggestions?
#32 of 84 Drove 2009 Altima in manual by accident. =[ by jjan Feb 26, 2009 (12:08 am)
I accidently drove my brand new 2009 Altima (automatic) for ~4 miles in manual mode without realizing it. I don't even know how to drive manual.   It was making it's normal noises, but when I sped up to about 40 mph, I kept hearing a LOUD grinding type mechanical noise from engine. I thought it was something else. Then when I stopped the sound stopped too. That's when I realized that my gear shift was accidentally on the manual side.   It's been driving fine since the incident, but have I damaged anything?? When I go for my first service checkup, what should I tell them to check out?   THANKS Replies to this message: madpistol (Feb 26, 2009 11:10 am)

Replying to: jjan (Feb 26, 2009 12:08 am) It's been driving fine since the incident, but have I damaged anything?? When I go for my first service checkup, what should I tell them to check out?   It depends. If the car is still in its break-in period (first 1000-1200 miles), then it couldn't hurt to ask. However, if you're out of that break-in period, you shouldn't worry about it.   My '08 Altima 2.5 SL has 14k miles on it now, and I take it onto some curvy mountain roads quite a bit. While I drive it, I try and keep the revs above 3k so that power is always on tap. I've done this many times, and the engine is just as happy as the day I bought it. The car is built for this. If it wasn't, it wouldn't have a 6-speed manual mode.
