It tapping noise on drive only red light stops on neutral doesn't make no noise at all like I said soon I left brake go few seconds the noise goes away but when I hold the brake for few seconds when car goes to idle then goes to tapping noise again sounds like under dash middle
Does it make the tapping sound when you shift the transmission in reverse and simulate a stop at a "red light"?? As stated in my previous post, I know nothing about automatic transmissions or the sounds they make. I don't know if a "tapping noise" from the transmission is benign or something serious.
Personally, I've never owned an automatic transmission vehicle.
Again, you'll need to try to narrow down the location of this tapping sound. Do you have a friend that will hold the brake down (with transmission in drive -- simulating this red light situation) so you can attempt to locate this tapping noise. If the tapping sound is coming from under the dash, I imagine you can confirm this by looking up under the dash from the passenger side foot well.
And yes, I understand that strange noises are bothersome. My old work truck squeaks and creeks with all kinds of sounds. The plastic parts inside the cab have warped over the years and rub against each other. There is nothing wrong (mechanically) with this truck, so I live with the odd sounds it makes.
