I replaced the clutch 2000 miles ago. Now all of a sudden, you can not shift the car while the engine is on. Will not go w/o forcing. Once you shut off the car and depress the clutch, no problems going between the gears. If you start the car with the clutched depressed, you will get a slight drag of the clutch and the car will want to pull forward. Master cyl and slave units are both new and working. Using the clutch seems fine when you push on it weather the car is on or off. Just will not go into gear when the car is on (in any gear). I'm puzzled and need some advice. Thank-you. Steve

Eother your clutch disc or pressure plate or both are warped. If you installed a "rebuilt" unit before, this is real common. Also, when installing a new clutch assm, it is very important that the flywheel is resurfaced to eliminate any warps or hard spots.

Actually, The Clutch was brand new, the pressure plate brand new and the flywheel was surfaced.

Do you feel resistance right away on the pedal or do you have a lot of "free pedal" before you feel resistance?

Very littl free play, approx 1/2". I've looked at the slave unit travel from the outside of the transmission, and see movement consistant to what I would expct to see. I've never had a new clutch become faulty under normal use, bu I'm afraid I may need to pull it out again and look it over. Perhaps the throw-out bearing or fork is defective?

Usually, if the throwout bearing is acting up, it'll make noise. Forks have been known to bend, but it's very rare. The problem you're going to have is when you disassemble the clutch, it's almost impossible to visually see a defect in the clutch assembly. If your lucky, you may see a "hot" spot on the pressure plate but maybe not. Let me know what you find.

Latest update. IT appears that the throw-out bearing has an inner sleeve that was starting to bind with the pressure plate forks. It is damaged and now I can not find a replacement. I've purchased several bearings, but none seem to come with this extra bearing sleeve. Any suggestions? I can send a photo if that helps.

I know the part you're looking for. It's the sleeve that the TO bearing presses onto. The chances of your finding a used one anywhere are "poor to none". Looks like it's going to be a dealer only item.
