2000 Chevy Venture 6 cyl Automatic 65000 miles

For the last two months, there has been an intermittent whining sound coming from the engine while the car is in motion. Actuially sounds like it is laboring like a truck up a hill (that sound you might hear just before you change to a higher gear). Well in this case the sound is there, but the gears change as usual, and the vehicle performs as usual. It is only a difference in sound. As I said, this happens intermittently, so when I have taken it in to the shop, they can't duplicate conditions. One day, I had the scenario, so I stopped by the shop. After listening to it in neutral and driving it a bit, they turnd it off and said that it was a hard one to diagnose, but. It could be my water pump needs to be changed, and something is sticking at times, and tht is why the sound is intermittent. They also pronounced my transmission to be okay. I am not sure I follow the logic, so can you explain it, if that is indeed what is causing this sound. Any advice is greatly appreciated. Thanks a bunch.

So it makes the noise in neutral as well. Could be the trans even if it is working properly, the pump may be having a problem. Can you tell if the noise is coming from the front or rear of the engine?

I will check the next time the noise occurs. Ironically it is intermittent, and I will just have to wait until it happens again, then I will follow up with you.
Thanks for your response.
