I can't shift into gear any longer and you can smell the clutch. I believe I need a new clutch.

Being shut out of gear like that is an indication that your clutch is not disengaging even when the clutch pedal is down. Revving to 3000 rpm matches speeds inside the gearbox, in effect shifting without clutch action.

I believe your clutch cable is broken, unattached at one end or the other, or is too slack to release the clutch.

If the car won't shift into gear, the smell of rubber is probably the clutch pressure plate slipping on the flywheel instead of engaging it. This indicates the need for a clutch repair. Could be a worn clutch pressure plate and/or a worn throwout bearing/fork. This is a job which can be done by a home mechanic, but if you don't have tools, floor jacks/stands, take the car to a mechanic.

The sounds like the cluch went bad. the smell and the reason you cant shift gears is due to the clutch. the clutch is burning and thats the smell, when the clutch gets low and slips it smells and sometimes it just blows apart due to wear. have the clutch checked and you will find it needs replacing. hope this is helpful have a good day.

Sounds like the clutch friction plate was on the way out when you bought the car. The smell you mentioned was probably from the clutch plate slipping.
You need someone knowledgeable to check the linkage is correctly set up and advise if a new clutch plate is required.

I believe your pressure plate is broken and at a minimum will have to be replaced along with the clutch disk.

once you have bled out all the air ,if the pedal still engages right down then suspect the fingers on the release plate are worn.Never replace a part of the clutch, allways change all 3 components,it save all the hastle of taking it to bits again and again.

I would definately suspect that, and also the master cylinder associated with it.

The smell of a burned clutch is one that permeates the car for quite sometime after the incident. It may take as long as two weeks for the smell to alleviate.

Meanwhile if the car is shifting normally and not slipping I would say the clutch is ok.

if its manual sounds like your clutch could be slipping does car smell of burt clutch?
check cluth adjustment
may need new clutch
do stall test with hand brake on, foot (heel-toe) on brake and accel pedal to about 2000rpm then let out clutch and car should stall if engine revs go down and engine still runs but you can rev causing slip and you will now smell what slipping burnt clutch is replace it.

if its auto check trans oil level and what does it look like red-good
darker red to black-bad often smells burnt also possibly new trans required.

it has a hydralic clutch check the fluid in it. it looks just like the brake master cylinder
