this was also posted in the “what are you doing today” thread, but it will have more future value I think, over here. Copy:
************
2015 CRV, (CVT), 5 qts of ATF drained/filled. 85k miles. This was interesting.
CVT had drain/fill at 50k with Honda hcf-2. No issue, no change in any characteristic. this winter, we noticed a rattle sound when cruising neighborhood decorations at low speed. It sounded a lot like a cranky AC compressor, but then realized it wasn’t. It happened consistently around 1300-1700 rpm, but only at creeping speeds. Very repeatable, and very easy to hear (obvious) and very much like an ignorable aging compressor.
4.5 quarts of hcf-2 sucked out. It was dark, but reasonably dark; nothing to be alarmed about.
5 quarts of amsoil CVT fluid went in. I drove it around a few miles and then sucked out the extra half quart.
um, even my wife noticed the change. Now, this vehicle hasn’t missed a beat and drives great, so we weren’t chasing a problem. But it is slightly quieter, feels more direct, feels surprisingly sporty-ready to go. And, the transmission is *almost* silent in that low rpm neighborhood creep mode. It has a notable change in feel, more than I would have expected. Will keep an eye on this. Good stuff.
