I think what you guys are describing is normal behavior for the cvt. Its actually trying to put the car in the most fuel efficent gear ratio as possible. As you said, I think it gets confussed at times. but, just put it in manual mode. that will lock it into a particular gear ratio and your problem should go away.

The technician at my dealer said that he did feel the problem I described, but that all the CVTs do the same thing, and there's nothing they can do. But he also said Nissan might eventually decide to do something about it, because it *is* annoying.
Maybe it's simply a software issue and they might release a fix for it.

Thats exactly what it is. the manual says the CVT is pre-programed with about 300 algorithms that control how it shifts.

I drove a rental 07 Altima 2.5 with the CVT and did not notice this problem. I later had a Dodge Caliber with a "CVT" and it DID have this problem.

07 Altima CVT 1500 rpm rumble

I have a 2007 Altima CVT and when the revs get to around 1500 rpm there is a rumble that can be heard and a vibration is set up that my passengers also note.
I have taken it to the dealer and we took out another new car, and it had a similar vibration, even though it was a bit less.
Does anyone else have this problem. Has anyone heard of a fix?

Is this the 2.5 or 3.5 engine?

My Altima is doing relatively the same thing. While driving between 30 - 40 mph in the city there is a vibration - like the tires are very out of balance. The dealership told me it was the transmission searching for a gear. They said to put it in manual and it won't do it. If I wanted a manual transmission I would have bought one. This is unacceptable to me. But the really bad thing is... I bought two 2007 Altimas. How dumb am I? The engine rattles on both, the transmission bogs down at 20-30 mph, it's very loud, and I could just scream! I've been so frustrated that I just traded one of them in, after only 6 months, on a real car - a Honda! Yep, I lost a few thousand dollars but at least when I drive the Honda I can concentrate on driving and not all the rattles and squeaks and the other annoying things. I've never been so unsatisfied with a brand new vehicle. If I had not refinanced it with the credit union, I would take it back to the dealership and tell them to stuff it!

CVT transmission question

How does this transmission work if someone can it expain without being TO Technical. How is this better than gears? I know it uses a metal band. Won't this band stretch out or wear down eventually? I drive 100 miles a day and i need to know the reliablility of this type of transmission. I have an 04 Pathfinder and i hate to sell it but the price of gas is taking its toll on my wallet now :o(
