clunk and binding in the rear
Ok so coming back home from the movies the other night, I was getting onto the onramp and as I was accelerating in 3rd gear, there was a loud clunking noise. I pulled over right away and checked underneath....nothing looked abnormal and there was nothing on the road. I get back in and try it again and I get a clunking along with a binding, as if something is holding it back. Anyway, I tow it home and put it up on jack stands today. I checked my clutch and that was ok, checked the CV's and those seem fine, there is no play in them. I removed the rear tires and checked to see if maybe the brakes screwed up and was causing the bind but those too were ok. I replaced the tires and then spun one while in neutral....no noise and no binding. I put the car in 5th gear and spun the wheel....this time it spun but the clunking was there and only when I spun it slow did it stop clunking allowing the other tire to rotate. Same result when I tried it in 3rd gear. What is your ideas on what it is....probably gearbox?

Check the CV axles. Typically issues with these present under load - jacking up and spinning tires doesn't always show.
From what I understand you can get rebuilt ones from your FLAPS for around $60 USD each.

Drain the transaxle fluid, see if there are chunks of metal in it.

Sorry to tell you; these exact symptoms happened to me a few months ago. It's the transmission. I had to change mine in the snow on gravel.

When you drain the oil, you may not see metal. Get a magnetic probe and stick it inside the transmission and see if it picks up any metal. There's a magnet inside the transmission but it's behind the big round access panel on the passenger side. With this big a noise though, it'll probably be pretty obvious. Good Luck.

Definitely a bad transmission. I blew the transmission in My first 944 I had when I was young 4 times because I didn't know how to not beat on it :-/ I was lucky and never spent over $100 on a used transmission. I can swap a transmission in an hour now haha got pretty good at it. But from what your saying I'm almost 100% positive its the tranny.
