2000 Audi A6 2.7T (150k) 6 spd Transmission Problem
I have the above mentioned. Few weeks ago it stopped shifting into any gears. I just bought it, so I'm not sure when, if ever, the clutch work has been done or hydraulics have been ever replaced.
I did notice slave was leaking. The pedal didn't REALLY feel spongy, or went down to the floor when the clutch did work, for about a week after I bought it. One day I started the car and it didn't shift into any gears. Naturally so, I started with replacement of slave/cylinder.
I'm 100% positive I did it right along with bleeding, however the car is still not shifting into any gears. Would my assumption that the next step would be to do the clutch work (disk, pressure plate, bearing) be right? What other possibilities could I be facing? I should mention that it's a one owner car until 150k, it was serviced at an Audi dealership until those miles. Carfax shows some history, but no mention of transmission work. The engine on this car is IMMACULATE, which tells me the owner took care of it. And the fact that someone drove for 150k on one car with 6 speed tells me they probably knew how to drive right. Any suggestions?
Thanks in advance...

So you cannot move the gearshift lever into any gear when the clutch pedal is on the floor with the engine running?
In that case it might be the master cylinder or the slave cylinder. Theoretically it could be a broken fork lever or a seized clutch disk and pressure plate, but that's rare.
A worn clutch not being able to MOVE the car with the engine, i.e., once it is in gear with the clutch pedal is off the floor the engine revs up and the car doesn't move accordingly. This is most often felt in a higher gear.
If you can put the gearshift into first, for example, when the engine is off, that doesn't mean the clutch is bad. Doesn't mean it isn't either, you must understand.

With the car off, I can shift into any gear with clutch pedal pressed to the floor. When the car is on, I can not shift into any gear, including reverse.
It did definitely feel like it was revving up a bit too much for how well the car moved, especially in 3rd and 4th. So, according to your theory this is more than likely a clutch problem.
And you replaced the slave. And bled it.
When you bled it, did you get a lot of fluid with each stroke of the pedal?
That would indicate the master is also working. Else, it could easily be the master too. I'd stop replacing parts until you have a better idea what' broken.
I dont see how a bad clutch disk or pressure plate could cause this. If the clutch was worn, it would smoothly shift into gear, and then slip. More or less ditto the pressure plate.
I'm thinking about the throw-out bearing. Unless you heard a lot of noise or felt a lot of roughness just before it stopped shifting, i'd doubt the TOB is bad. If it WERE bad, i suppose it could prevent the clutch from sliding.....never seen it work quite that way before though.
Are you certain you dont have a linkage problem?
