Noise shortly after moving away (cvt)
« on: June 30, 2020, 10:03:32 PM »
This was happening ever since I had the car and I donít know whether itís serious or not. When I start the car, change gear to Drive or Reverse, and start moving away (usually slowly on the brake rather than with gas), after a short distance (like 2 carís length) the car makes a buzzing sound that lasts about a second. The faster I am moving the shorter it is. There is no vibration, just the sound. It sounds similar to the judder I had before that was fixed by changing CVT fluid recently, only much much more gentle than the judder. Also judder was related to moving away from a stop. The gentle buzzing noise I am talking about now only happens first time when I change to the gear. As long as my car is in Drive the sound never repeats no matter how many times I stop and move away. However if I stop and change to Reverse it will happen again, and then when I change back to Drive - again. Every time I first engage a direction. What puzzles me the most it is not immediate when pulling away. It only occurs after I start moving the car. That is, when doing a tight 3-point turn (when itís actually a 5 point turn) it wonít come on after each change because the distance driven between changing direction is too short to cause it. Only when I finally move away for good it sounds. When I move away with accelerator I think it comes on but lasts shorter, however I canít be 100% sure as the sound is not loud enough to hear it with revs. My mechanical knowledge is next to nothing I am sorry if this problem is obvious or has been answere here before, I browsed this forum before but couldnít find exactly the same description. I am interested to know whether itís serious as I intend to keep the car for a few years. Thanks

When the CVT fluid was changed, was it a full 6 litre change ? Or just a drain of the 2liters that comes out when drained and refill.

If teh latter, it is likely the previously dirty fluid has contaminated the new fluid.
Do another change

This has been done at honda a few thousands miles ago and they said they may need to change it once or twice, I left them the car and they said it only needed one change. I donít know how many litres. From the old service book (before i had the car) it had FDSH but it seems the CVT fluid has never been changed before so it is possible I had it changed the first time after 15 years. The car had only 60k miles on when I bought it 18 months ago. Like I said it is similar but different to the judder I always had until the fluid was changed, the judder could happen when moving away at traffic lights or roundabout with Ątoo much revsĒ, now itís only after changing direction forward / reverse. It was in place since I got the car I just havenít paid attention, now that I am confident I want to keep the car for some years Iíd rather not neglect anything. Car still being serviced at honda but they are not good at picking up everything that might be wrong in such old cars
