Bad motor / transmission mounts?
I have been having an issue where if you let off the throttle for a few seconds and reapply the throttle, it feels like there is drivetrain lash, and the car will buckle a little and you can hear it. It is more prevalent in the lower gears.
Background
02 S2k
70k miles
I daily drive it/never been tracked and rarely beat on it.
Not modded at all
never seen a winter
I just replaced the 4 diff mounts with OEM even though they looked fine and that did not fix it. I was going to try the transmission then motor mounts but wanted to get more input before spending the money. I visually inspected the motor/trans mounts and they are not cracked or leaking. I tried the test where you use the e-brake and lurch it a bit to watch for excess movement of the engine but it didn't seem like it moved all that much.

I'd be very interested in this aswell... i have the exact same issue and started to notice it after my clutch and diff have been replaced (with oem parts).

can you move your motor by hand? do you get any shifter movement when turning your motor on/off? Have you been under the car and rotated the driveshaft, there will probably be a certain amount of play inherently.

i just got my motor mount changed,
i had lots of vibrations and i knew something was wrong but just didnt know what it was.
a local shop looked at it for 2 secs and knew it was busted motor mounts.
it feels and drives like a new car.
no vibrations! look in to it!
btw i went stock, the cheapest

Is it possible they messed up the mounts when they changed my clutch (since they have to lower the engine a little)? I definately didn't have this issue before the clutch change.
I think i'll just take the car back to the dealer and talk to them about it...

So I finally got around to swapping them out and the pic below is what I found for the driver side mount. There was no leaky red stuff and looked find until I actually lifted it and took it out. I had no shakes or anything on accel but the engine did wobble a little at idle. The drive train slack is about 90% gone now. The transmission ones were mediocre at best and pretty squishy. The new ones are more stable and there is no shifter movement at idle now, there was only a little movement before but they were cheap and worth the change while I was down there. My friend helped me with the front mounts so between the two of us it only took about an hour.
