Default Possible tranny/clutch problem

Ok I was wondering if this was normal. I have a 95 T/A m6 with less than 57k miles. I'm not sure if its still on the original clutch,throw out bearing,slave cylinder and all other related parts. When I come to a stop in traffic or at a stop light or stop sign and I try to put into 1st gear it will NOT go. So I have to release the clutch and press it in again then it goes right in. Also when I am on the interstate cruising at 70-80 mpg I get a whining sound in a rhythmic sound...I am not sure how to describe it. And I get a considerable amount of vibration through my gear shifter. Also at idle I get a good amount of vibration enough to vibrate my passenger seat so you can visisbly see the head rest moving back and forth....Any help will be appreciated

Sounds like the 1st Gear Synchro is out. That sound at 80ish could be Drive Shaft vibration.

Is the vibration at idle coming from the Tranny area..?

Yeah that sounds like 1st gear syncro. nothing you can really do, just deal with it - it doesnt really justify a tranny rebuild in itself.

and the whining sound is most likely driveshaft IMO. no big deal either.

I agree. I have just thought about getting an aluminum driveshaft from an LS1 car and using that.
