Well, I am pretty sure the clunking was caused by the motor mount

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I get a clunk when shifting from 1 to 2 or 2 to 3 over 3000 RPM when cold
The clunk happens when I depress the clutch and is from the back of the car. It does seem to be more on the right than the left and definitely in the rear
Once the car warms up , the clunk goes away or at very least a very quite clunk
I have ~ 80k on the car with the original motor mount. I looked at the CVs and all have perfect boots and no leaks. I thought it might be the motor mount, but with the problem not happening when the car is warmed up, I'm not so sure. Also there is no vibration in the car or shifter nor any movement in the shifter.
Any ideas to what the problem is?
Hello GTSilber,
that is pretty easy. First i use Photoshop to correct the photo – so that i can see the damage.
And there you see that the upper part of the black gum is completely tored off and broken out - means you will have contact under torque.
There is another thread where you can see other worn mounts and a new one:

On the second side i did some photos.

I considered pressing in a new bushing as well but the problem is that if you don't have quick access to a press the car would be out of commission for as long as it takes for you to find a place that is able to swap the bushing for you. So for me the extra $100 or so is worth is it because I won't have to worry about the car being in a state of disassembly while I figure out swapping the bushing.
****** UPDATE *******
Got the insert pressed in at a machine shop. Cost $25
Installed it back in the car and took it for a test drive.........
Smooth as silk!!! :dance:
All in all probably around 3-4 hours including jacking up the car and getting the insert pressed in. Its a reasonable easy DIY
This thread is very helpful

Total cost
$35 for the insert
$55 for the shims
$25 for pressing the insert in
--------
$115
Had I bought a new mount, I would still need the new shims. I effectively paid $60 for a new mount
