Default Clunking Sound

Alright, I have ran into my first 'issue.'

When I shift at roughly 2500 RPM, and let the clutch out quick, there is a clunking sound almost. It comes from under the car, so immediately it had me thinking bad u-joints. I was also told, if the torque arm mount is bad, it will also make a clunking noise.

Well when I had the car in the air to bleed the slave cylinder, I looked at the torque arm mount, and visibly, the mount looks to be in good shape. I never touched the driveshaft, to see if there is any play in it, but I was just seeing if this was a fairly common problem. So I was looking for some ideas, so that I can fix it.

FYI- The car has an aluminum driveshaft, and the car has 50k miles on it.

Could be a number of things, motor mount going out, y-pipe hitting the floor, bad u-joints, tranny mount going out. You have to remember that when you shift hard, everything torques toward the passenger side of the car. Eliminate the good and fix the bad.

I am thinking it is the tranny mount. How can you tell if the mount is bad, other than pulling it off the car and inspecting it?

I have the same problem but i changed the trans mount and motor mounts to poly and it is still there i think the floor board might be flexing from the tunnel mount torque arm but i am not sure
