Hi, Guys
Actually, I found this weird sound since I got it. But did not put here to be discussed. Maybe you guys noticed also, or just mine.
this sounds like "puchi", it is hard to describe. But it only happens when I fire up the car, then wait for it being warm up. it idles for 1 min, when the temperature gauge starts moving. then this sound comes. it is like something like valve open up?

Do you guys hear the same thing?

Have you changed your trans filter yet?

Yes, I did replace the tranny filter last year.
But the gurgle sound from tranny filter is on the moment of firing up the engine at cold start. (actually, it came back around 2 months after replacing the tranny filter)
this sound is after 1 min or 2 mins after startup, pretty much before gauge starts moving

So what was the noise OP?
