Default Drivetrain Vibration While In Gear

For a few months now if had an issue with my car. Let's say I'm in 2nd gear getting ready to shift into 3rd at about 3000-3500rpms. Theres always a vibration coming from under the car. Even if i hold the clutch in, there's a vibration until I pull the shifter out of gear. This only happens when the RPMs would be high if I were to let the clutch out. So if I'm in 4th cruising at 35mph and downshift to 2nd, there's a bad vibration, even before letting the clutch out. Almost like my clutch doesnt fully disengage. This happens in every gear and gets worse as my RPMs climb. But it still does it if I push in the clutch.. I'm lost as to what it could be. Also note, there's no vibration while revving all the way up to redline if I'm in neutral. Only when the car is in gear. If I have the car in, let's say, 2nd with the clutch in while cruising at 30-50 and rev the motor, the vibration doesn't change with rpm fluctuation. It only gets worse with the clutch out when the RPMs fluctuate. When I push in the clutch, the vibration gets slightly better but still remains there. Any ideas? Bad clutch, flywheel, throwing bearing? Hydraulics? Any ideas???

Or a main bearing. I know the trans in my 69 is going bad, makes a lot of noise while driving and going through gears. Maybe I should stay off the throttle :P

Did you replace your two-piece driveshaft with a one-piece shaft?

if it only does it in gear i would say its in the trans or clutch. have you checked to make sure the bolts to the clutch are tight?

Remove and inspect your Trans Mount... Might also want to look into new motor mounts -- how many miles on the car? It is a '94, which is a lot of years.

The tranny mount is good. I haven't checked the clutch. I don't think it's anything that has to do with the motor because it only does it when the car is in gear. Never while in neutral.
