I have a weird sounds that sounds similar to running over the drunk strips on the sides of the highway. It only happens for about 1 second but I can hear it everytime I move the car about 10-25 feet after I first start it up; after it does it once I'll never hear it again until I start it up the next time. It almost sounds like it coming from the ABS block, but with all the stuff under the hood it's really hard to tell where the noise is coming from. Thanks for any help.

 

Forgot to note that it has an auto trans.
