2005 Pontiac Vibe / 80k miles
There is a whine/buzz when starting car that seems to go away after a while. Maybe the audio quality in the video is enough to capture it -- https://www.youtube.com/watch?v=N5EzXgPPRWo
-- at the 4/5 second mark is the car shifting into reverse (noise changes).
Any quick ideas? A shop did recently change the ATF fluid several weeks ago / last month but it was not a flush. I don't know if that means anything.
- Still happens with belt off.
- Short recording of reverse noise (at very end, sorry!): https://vocaroo.com/d9wAzXnjldP
Could a bad motor mount push the engine against some metal / etc when shifting into reverse maybe? You can tell I'm a bit clueless.
- Talked to a person at a transmission shop. He said it is possibly / likely the transmission torque converter. Also,
he optimistically said that since the noise vanishes after the transmission fluid is warmed up then maybe the new fluid they used takes longer to heat up or is thinner than what was there. I may hit up the shop that did the fluid change to see exactly which kind they used out of curiosity. It was NOT a flush by the way.
