Transmission noise (growl)

Sounds like a loose wheel, check them ,

Sounds like a gear grinding. Check fluid and see the color and look for any metal shavings also have vehicle scanned for transmission codes

and the mystery vehicle is?

i have been fooled by this one way to many times. when a wheel bearing or hub assesembly is making noise, it will sound like it is comming from the other side. i do not know why this is. but one test will prove if and which one. when growling noise occurs, notice, when turning left or right, does noise get louder and quieter as you turn? if so then it is wheel bearing. when turning left the right side will make more noise. when turning right the left side will make more noise. if always the same then, tires or transmission need addressing. the cv axle does not make a growling noise, unless front wheel drive car does not move, it makes a clicking or poping noise. sorry but at least you dont have to replace other axle

Tons of possibilities here (transmission, differential, motor mounts, transmission mounts....), so I'll ask some debug questions to help narrow it down. Does it make the noise when shifting into reverse? Also, does it make the noise only when shifting from park, or also when shifting from neutral (into drive or into reverse)? Did the noise start as an occasional, softer noise and get worse over time, or did it start suddenly? Does the vehicle lurch at the same time as the noise? What happens when you go from Reverse to Drive, or vice versa? Has any work been done recently (brakes, tires, alignment, suspension, transmission)?

This could be one of two things. We will first start with a wheel bearing. When you are driving, does the growling noise get louder as you go faster. Some times is will sound like you have a helicopter flying beside you depending on how bad the bearing is. The second thing that could be causing the growling noise is your transmission. There are also bearings inside your transmission that could be causing the noise. If you have a cvt transmission, you have a 120,000 mile warranty and can have it repaired at no cost to you. You will just have to go to a nissan dealership.

If it is filled up to the "full hot" mark then you are okay, fluid wise. It almost sounds like once it gets warmed up, it starts running better. The "growling" noise (especially when turning) could be from it not getting enough fluid. Other than that, your power steering pump maybe on its last legs, and it is taking time to warm up before it starts pumping fluid correctly. Just make sure that you power steering resevoir is completely filled to the proper mark.

I have had similar complaints that turned out to be the Idle Air Control (IAC) solenoid. The solenoid can get a little weak and air coming in through the intake at certain speeds can cause it to start vibrating. It sets off a moaning sound that resonates through the intake ducts and can get VERY loud. Sometimes it almost sounds like a fog horn.

If this is the type of noise you are hearing, replacing the IAC will fix it.

Other than that, the only suggestion I have is to see if you can get it to make the noise while the vehicle is sitting still. Slowly accelerate the engine speed with the vehicle stopped and the transmission PARK to see if it will make the noise. If the vehicle has to be moving to make the noise, then that eliminates several possibilities like the IAC, fan clutch, pullies, etc.....things that operate the same whether the vehicle is moving or sitting still.

Is it a auto or manuel ****** , but either way it sounds like either the rear bushing is worn or the bearing or even possibly the u-joint .......

Are you sure this isn't the clutch release bearing making noise, I bet it is.
