    Whenever I back out of a parking space, I hear a "pewwww" sound, almost like a valve being release? I have the 3400 V6 AUTO

    When I initially read this, I was thinking gear noise that I have with the manual. Then I saw the valve releasing part and I am :confused:

    Sounds like a U-joint.

    I assume you pull into your driveway.
    When you reverse, the u-joint basically gets thrown the opposite direction when backing. So it takes that little bit of "slack" and hits making a ping noise. When mine started to go bad they made a similar noise.

    I don't think it's a ping noise generated from two surfaces making contact...

    it's a very soft noise, like the above link I sent except it sound slower and very muffled..

    I wonder if a valve or similar mechanism inside the automatic transmission is causing it ... ??? ...

    I know the sound. Mine did it too. It is like a small motor spooling up or down. Lasts less than a second. I chose to ignore it, not sure if the truck still does it.

    I thought the same thing, like it was his first manual. It sure surprised me the first time I heard it in a stick shift car. Mine has scared a few people who thought the old Taco was about to explode.
