HELP!!! Toyota Corolla 2005 squeaking noise...

Hi, I got a problem with my Toyota Altis Corolla 1.8L (1ZZ-FE engine) (Automatic). Everytime I slow down and stop, and shift to neutral then to drive it makes a squeaking noise. then if you shift it back to neutral it doesn't make the squeaking noise. It only happens everytime you shift from neutral to drive.

What could the problem be??? I brought it to an authorized Toyota dealership a couple of time already to have them check whats causing it. but they can pin point whats causing it...

can you describe the squeaking noise? because usually squeaking is caused by belts, or bearings (different kinds of squeak) how does it sound and can you produce that sound at any other time?

Hmm, its like a faint noise something like "errrk" before i thought my tires were causing the noise, but it wasn't it. Take note when i shift from neutral to drive im stepping on the brakes. It also make the sound when i slow down then accelerate. My ATF fluid is full.

I also tried it out in my garage, while pressing the brakes, i tried shifting from neutral to drive then drive to neutral, it only makes the sound when i shift neutral to drive.

after doing that like 5 times the sound stops.
