transaxle noise

i've a 98 z24. whenever i put it in gear and accelerate there an intermitten noise coming from under the car that i've pinpointed to where the drive shafts go into the trans. but i'm not sure which side or if its in the trans. has anyone had a similar problem that can tell me if its the trans or possibly the drive shafts?

I have the smae problem what was it?

Please describe the sound. A clunk or thump would have a different diagnosis than a ticking, growling, or ringing sound.
