Question about 1997 Chevrolet Blazer
It feels like it is shifting but I can only get it up to about between 20 and 30 mph. It makes kinda like a loud noise like it is maybe sucking air. I'm bad at explaining it.

Common cause is the drums and brake shoes need to be replaced. When there no longer within the the specification for the brakes to work properly, the self adjusters will over adjust the brake shoes and you'll have the feeling of the rear drum brakes lock up as the shoes will bind up along the drums. Replace both Shoes and Drums and this can be done on your own will common tools and a simple brake spring tool that you can pick up at Auto Zone or Parts Source and both can give you the step by step instructions to replacing the rear brake system. Good luck and be safe.

You are right to be concerned about this behavior since it can definitely increase your stopping distance.
Either your cable has eaten its way into the inner tubing and is hanging up, or the mechanics at the throttlebody needs some lubrication.
With no engine running, have someone inside to press on the accelerator while you watch for movement of the linkage under the hood. Once you have located it, operate it by hand to see how it feels. If the linkage does not return to the stops provided, then use a heavy-duty penetrating oil to soak the moving parts. If it still hangs, then the cable needs replacement.
With the engine running, tranny in Park and the parking brake on, after you have lubed the visible linkage, have some one inside press on the gas and watch the linkage to see if it now returns to the mechanical stop. Carefully move it by hand to see if it is truly at the limits of its travel where it should be at an idle.

One of the front wheel bearings are bad. Jack it up and see if one is loose, the noise will usually change if you swerve back and forth while driving. Could also be a rear pinion bearing in the rear axle.

SOURCE: whining noise
Can you make the noise happen with your foot on the brake, trans in gear, and a little throttle? And does it go away in park & neutral? If yes to both questions you probably have a faulty thrust bearing in the torque convertor. If no to both questions you like have a faulty "input drum to pump cover thrust bearing." Either way the problem must be repaired ASAP or when the bearing fails it will be at the worst possible time, like in the middle of an intersection with a firetruck bearing down on you.
