Possible tranny problem?

I have a 1987 Dodge Shadow manual transmission turbo that is making a rattling noise as I'm driving down the road... sounds like it's coming from the undercarriage. And it clunks when I shift gears except when the car is idle. I was thinking maybe it's the CV joints. Not sure. Any help is much appreciated. Thanks.

Don't think I've ever heard a failing cv joint noise described as rattling. Normally you get a clicking when turning or a pronounced vibration in the front end. Could be something like a loose exhaust system heat shield or even loose baffles inside the muffler/converter. The clunking when shifting could very well be the cv's. They're original maybe? Boots still intact? Any sign of loss of grease from the joint(s)?

How many miles on the beast?

Actually now that I listen to it a little better it's more like a grinding noise than a clunking. I'm probably gonna need a new tranny with my luck. I think the car has a couple hundred thousand on it but I'm not sure. The odometer has rolled over. I don't see any grease loss but it's really hard to see under that car. I'm gonna have to jack it up again and take a better look.

Grinding may be a tranny issue. Ever changed the gear oil in it? Clutch maybe also; possibly you're not getting a complete disengage when you mash the clutch and you're getting a little gear grinding?

I've only had the car for 4 months so I don't know what's been done to it. It was given to me... sort of. Long story... irrelevant. But I'm gonna check out those things you mentioned Mr. Tow and I'll get back to ya. Thanks a bunch.

If it makes the noise at idle while you have your foot on the clutch its the throw out/release bearing.
Or it could be the springs in the clutch plate hold on no you changed it to grinding, that means moving parts are touching.
It does sound like a clutch or tranny prob.
change the oil in the trans taking note of whats stuck to the magnetic drian plug if its like silky gray between your fingers this is norm, anything bigger than a grain of rice and soilid you may have a trans prob.
kinda hard to tell without hearing it.
