I don't!

Is that the same as the "heavy-duty friction-modifier" another poster mentioned?

Do you just add it where you would add the transmission fluid?

Yes!

LUBEGARD® Highly Friction Modified (HFM) Automatic Transmission Fluid can be added to any Automatic transmission fluid ATF (except CVT, DCT, and Ford Type F [1986 and earlier models] fluid). For normal applications, add 1 oz. (29.6 mL) of LUBEGARD® HFM Automatic Transmission Fluid to 1 qt. (1 L) of ATF for the total capacity of the transmission with motor idling. DO NOT OVERFILL.

Took my Sentra to a transmission shop last week....one that works on CVTs....and the guy there said that he didn't think my chirp was from the CVT. I guess that takes me back to square one as to trying to figure out what it is.

OP~ Does it quit "chirping" when driven in heavy rain?

It does not. Seems to make the noise in any kind of weather....though the problem didn't start until spring, so I don't know how freezing cold with effect it.

I also tried something to remove the brakes as the culprit. When the noise starts, I keep accelerating but tap on the brakes. The noise remains.
