strange clunking when shifting. So basically when I shift casually (not fast or hard, just normal) the transmission or something in the center of mass of the car seems to clunk/bang in a forward/back jerking motion, (not extremely hard, but like you hit a bump, that hard) also, if I let off the clutch a little fast and sometimes normal, it does this. This also happens if I let off the gas quickly. Does anyone know the possible cause of this problem? Apparently it is as common as the squeak our cars make when going over speed bumps. Any info would be greatly appreciated, It can sometimes make driving stick frustrating because u have to shift fast& baby the clutch and gas to have a smooth ride and keep from having the clunks.

Check the transmission mount first, if not it then torque arm mount, if both of those check out then you may have a problem on the inside of the transmission... Which is what I had, think I broke a bearing somewhere allowing movement in the main shaft but havnt broken it down to determine. Swapped the transmission and no more clunk on shifting and stopping

Yes, replacing the mount completely solved the problem, and the thing is, it appeared completely fine to the naked eye when I pulled it. With yours visibly completely falling apart, the difference will be night and day.

I checked the bushing and it looked ok but there were some gaps where it wasn't touching the arm and when I touched/rubbed it rubber started chunking off, so I think I have found the problem. I can post a video if anyone wants to see it. Anyone know a good place to find the bushing?

is this the right part? there are other parts that look very similar but they don't specify year.

Alright. I will call up somewhere tomorrow and get a rubber replacement. Heard it is a bitch to install though because of the top bolt or something.
I don't know if you thought of this, but I found it by accident. I pulled the air injection hose at the fitting near the driver shock tower and plugged it as a temporary bypass to theair system, and the car quit clunking. Hooked it back up to pass emissions, clunking returned, which is when I put two and two together. The check valve was leaking, causing cold air to enter the exhaust and make a small backfire, but it sounded just like the y pipe was hitting the transmission case when shifting. What clued me off was your "even happens when I suddenly let off the gas".
Quick and easy to check if you haven't already plated off your air injection ports

torque arm rubber bushing is the clunking when shifting i aint sure if its supposed to but id say sort of is cause as you take off the rear end tends to rotate forward so th armis pushed down, then when you let of gas the bar goes up thats the play and banging you hear
