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.
