These transmissions have three sets of planatery gears the whining you hear is simply the gears doing thier job. You have to remember the allison trans is basically the scaled down version of the heavy duty isuzu truck trans they are designed more for thier load capacity then for comfort

Chevy prizm 2001 whining


What is whining? Could be several things. Here are a couple of ideas.... Check Power Steering fluid level and transmission fluid level. However, if it is making noise while driving, it could be a wheel bearing. Good Luck.

High Pitched Whine


A high pitched whine like that indicates a bad bearing. Water pump, power steering pump, accessory belt slipping, alternator bearing, or in the worst case scenerio, Transmission pump.

Makes whining noise


This could be a stuck Bendix gear. The Bendix gear is the gear that engages with the flywheel on the engine when you start the car, and if it hasn't retracted it will whine.

Check with a local garage, but do so soon.

Could be your alternator or a bad idler pulley. Is the transmission good? It may be the tranny or your differential whining.

yes the front sensor will collect metal shavings causing this same problem.however you need to have it scanned when the lights are on. auto zone scans for free. the front sensors are in the front hubs. replace as a set as assymblies.

It is inside the transmission. It is called a reaction sun shell, it strips out, which causes the grind noise your talking about.
