Normal CVT Sounds

[kerrton]

I've noticed some somewhat unusual sounds from the CVT, and I was wondering if anyone else notices this as well. First of all, I'm NOT referring to the crazy loud rattle that those with transmission problems are dealing with (well I sure hope not anyway). What I notice is when I'm slowing down, using the brakes right when I'm almost stopped I'll hear a VERY brief, split second subtle rattle sound. Usually if I let off the brake at the last moment before I'm stopped, this causes the noise. It is so subtle that I hesitate to call it a noises, but I'm sure it's there. It is almost overshadowed by the sound of the engine, which is a little raspy sounding sometime too, but I'm sure that is normal.

Anyway, the question is: is a little bit of occaisional, brief noise like this the result of normal CVT operation, or might this be an indicator of a problem that is developing and will get worse? I tried to research this to determine if the CVT should make any sounds or if it should be whisper quiet at all times, and I didn't come up wtih anything. Phil, you mentioned in a previous post that you sometime notice some sounds coming from your transmission, is this similar to what you were referring to? Thanks.

Ours does that too. Seems like it's most noticeable when stopping quickly. It's as if the transmission is trying to "catch up" to the change in speed when stopping.

I recall others reporting similar experiences when researching, so I'm not concerned.

Hi I also have a Versa w/ CVT trans.

I also have the very brief rattle sound when stopping. The transmission does a ticking sound when putting in reverse too.

Doesn't look like a problem to me.

I haven't noticed that. I do, however, notice a small whine when slowing down at low speeds...like slowing before a speed bump. It sounds like a small jet engine winding down. Not loud, not annoying...just noticed it when I had my windows down.
