Engine whines while accelerator pressed
Hi, I have a 1999 Blazer 4x4 LT. At idle, the truck sounds like any V6, from the inside. When I give it gas while in gear, there is a mechanical whining that sounds close to the firewall. The whining gets a higher pitch the more you accelerate, until the tranny changes gears, when the whine starts all over with a lower pitch. I was wondering if this is normal for a 4x4? transfer case noise, perhaps? I rode in a friends newer trailblazer, and hers made no noise at all. It is a very smooth sound, not grating in any way. Maybe it's normal, just tranny transfer noise? These older blazers arn't as soundproofed as the newer ones. My wife calls it the squirrel cage sound.

Hmmm....could be something. Kind of hard to tell from your description. Can you elaborate anymore? Is there anything else going on besides a whining sound? Do you have any other noises or vibrations or anything like that? Any indicator lights on? Is your performance at all sluggish or does your blazer hesitate or shift oddly?

I would suggest checking the transmission and transfer case oil ASAP.

Also, how's your 4x4 working?

RE: Engine whines while accelerator pressed
now, you don't hear the whine while turning the steering wheel, do you? Have you checked the power steering fluid, because it would whine when turning the steering wheel if it was low.
