Please help! Problem with Nissan Maxima SE 2007

[LukaBratzi]

I started to experience squeaky noise coming from the front end of the vehicle. Whenever i stop or accelerate, go from "P" to "D" or shift to any position it gives me a squeaky or metal clicking sound. I think this has to do with transmission. May be it needs some lubrication? Also, either when accelerating or decelerating the 1000 rpm mark it also clicks and squeaks. The sound is continues for a short time and then goes away. Another issue is the "whistling/high pitch" noise. It tends to do so when i accelerate. When it starts i release my foot from the gas pedal for a moment and then accelerate again. This way it goes away. Again, may be something is rubbing against something.
