i notice upon hard acceleration when shifting an almost grinding noise comes from the center tunnel. but it deosnt make the noise when driving normally, could this be my clutch, the clutch and all the plates are new so i dont know what it is.

The problem is a bad acculmulator. I had this exact situation when I bought my car. I finally had the acculmulator changed and everything works the way it is supposed to now.

Difficult to DIY or not?

Had it done while doing the clutch

is cahnging the accumulator a difficult job or pricey?

sfbanchs

what is the consequence of not doing trhe repair right away, keep in mind i just spent a ton of $ replacing all the lifters and doing the front rotors and brakes. I am considering holding out on the accumulator unless your almighty rennlister knowledge advises me otherwise, please advise as soon as possible

It is best to change the slave and accumulator at the same time. The parts are about $700 and it's a fairly tough DIY, but doable. Do a search, as Marc in AK did this not too long ago. No real damage will be done if you wait and it won't strand you, but could start leaking hydraulic fluid from the reservior in the trunk right in front of the driver.

Marc in Alaska just did his. He posted pictures of the process..

the noise comes from the rear of the tunnel close to the engine would this stil lcause leaking in the front?

How about a squeak when you depress the clutch pedal? My 97 tt has this fault but it goes away after being driven?? Any ideas?

Why does this cause leaking fluid in the front of the car?

You need to do a search and read what has been covered previously. There is a backup reservior in front that is connected to the rear pump by a seal in the slave that fails.

would the grinding possibly be a worn-out synchro?

I see this thread popping up lately so I figured I'd update...I replaced the slave and accumulator a year ago and the clutch feels/works perfectly before/after startup even after extended sits (3+ weeks). Costs slave cylinder $688, pressure accumulator $106, Labor $320 (4 hours)
