check engine mounts especially the rear box mount because under high torque situations (1-2) gears there may be mis-alignment of the drive shaft occurring and the vibration is from "U" joints behind the gear box getting out of alignment and phase angle.. Check slip joints for lubrication and wear.
It's your exhaust mounts or broken exhaust bolts. It does it in drive st idle n under load because the motor is sitting in rubber mounts made to dampen vibration. Therefore the motor tilts to the left in reverse pulling the exhaust away from your under carraige, and to the right in drive causing the loose exhaust to vibrate against something. Check your heat shields also. They fall apart n do the same noise. Piece of cake.
You're absolutely right, it's not normal and in my opinion your Saturn dealer is lazy, incompetent, or both. At the very least it's indicative of how little they value you as a customer.
Your problem is almost certainly due to cracked or corroded ABS reluctor rings. Just do an online search on those three words and you'll see what I'm on about. Get a competent mechanic to check them for you promptly as it is a critical safety issue. On some brands the rings only come as part of a complete drive shaft or hub assembly, but there are usually third party suppliers who sell the rings separately. Usually they're a tight interference fit and must be heated until red hot before slipping them onto the drive shaft/hub. If not the rings, then it may be one or more of the sensors that operate in conjunction with the reluctors.
Please note that the advice I have given is generic to almost all ABS
equipped cars; I can't be specific to Saturn as I live in Europe (UK)
and Saturns aren't sold on our side of the pond.

Are your pads warn out ??
Is it metal on metal ?
If you can not determine if you pads are warn out - you should not attempt to replace pads and rotors yourself..
chevrolet uses tire pressure sensors for the system, check the tire pressure in all tires including spare and they should be set to about 38psi. If any of the tires are low it will trigger the abs because the abs system goes off wheel speed and a low tire will throw off the reading.
