Hi guys,
My VY V6 has an odd knocking / ticking sound coming from around the transmission. It's as though something at the front of the trans spins up when the engine starts, and once the engine is revved and the car moves a bit and when the engine drops back in revs, this thing starts to spin down a few seconds after and does this knocking / ticking sound while it slows. It has continued when the car has come to a standstill too so it's unrelated to road speed.
Video:
It only seems to do it after the car is started (even from warm); after it's been running for a minute or so it doesn't do it anymore until the car is stopped and restarted again. For example the car was warm from daytime use, I started it about two hours later and backed out of the driveway and heard the noise. I stopped the car moving and the sound continued. Engine noise makes it hard to hear from under the bonnet but it's quite noticeable in the cabin. The A/C unit was turned off so it's not A/C fan noise.
Any ideas?
Thanks!
Greg
